EndGetSelectedItems yields no items

Tim — Sat, 25 May 2013 17:08:47 GMT

Hi, slight panic here. I'm trying to get selected items from an ultimate ListBox and I'm getting 0 items. Selection changed is triggered when I hook to it, but I seem never to be able to get any items (despite Single/Multiple/Extended selection modes).

        private void GetSelectedItems()
        {
            IAsyncResult result = TaoListBox.BeginGetSelectedItems(
                (r) =>
                {
                    if (r.CompletedSynchronously)
                        return;
                    IEnumerable items = TaoListBox.EndGetSelectedItems(r);
                    CopySelectedToClipboard(items);
                }, null);
            if (result.IsCompleted)
            {
                IEnumerable items = TaoListBox.EndGetSelectedItems(result);
                CopySelectedToClipboard(items);
            }
        }


I am based on AsyncSqlDataSourceProvider, but it seems this should not make a difference since the data is already in the ListBox. Is there something else I have to turn on?  At items the Count is always 0.

Xceed in FoxPro 9.0 with Compression in Memory

Abh — Fri, 24 May 2013 11:47:08 GMT

Hi Everyone,

I am trying out compression of Strings using Xceed ZIP library. Though, I can create ZIP files, I am unable to use Memory Compression. The code I am using is as follows :

aaaaa
o=CREATEOBJECT("XceedSoftware.XceedCompression")

?o.License("ZIP65-xxxxx-xxxxx-xxxx")

ac=space(100)

=COMARRAY(o,10)

?o.Compress("abhay is a fool",@ac,.t.)

The call to compress returns 0 and the value of ac remains Blank.

Any help will be appreciated

Thanks in advance.

Chart number formatting

David — Thu, 23 May 2013 14:42:41 GMT

I can't for the life of me figure out how to format the values of the X axis in the chart control. We are dealing with fairly large values (from 0 to 387,292.37 for example) and I want to display the numbers with commas. 387,292.37 instead of 387292.37 for instance.

Xceed WPF controls sample

Phan — Fri, 24 May 2013 02:31:52 GMT

and do Xceed WPF control support for Coded UI test?

Cancel auto-select first row

Vyacheslav — Tue, 02 Apr 2013 02:56:32 GMT

Good day,

I am using DataGridControl. When I refreshing ItemsSource it default auto-select first row, but I dont't want this behavior. So how can I remove it?

Also I try selected row after refreshing. I used event ItemsSourceChangeCompleted but it doesn't work.

private void LoadData()

{

this.PeopleList = new List<People>();

this.PeopleList.Add(new People { Name="David", Age="22"});

this.PeopleList.Add(new People { Name="Anna", Age="20"});

this.NotifyPropertyChanged("PeopleList");

}

private void dataGrid_ItemsSourceChangeCompleted(object sender, EventArgs e)

{

var item = this.PeopleList.FirstOrDefault(q => q.Name == "Anna");

if (item != null)

this.dataGrid.SelectedItem = item;

else

this.dataGrid.SelectedItem = null;

}

In first loading event ItemsSourceChangeCompleted doesn't work. After refreshing it work.

Is it possible to create StatCells at runtime

David — Wed, 22 May 2013 18:50:23 GMT

I am currently working with a grid that has dynamically generated columns. I want a specific grouping to have a StatRow that contains a StatCell for each of the dynamically generated columns. After digging through this problem for a day I am still unsure of how to accomplish this. Would anyone happen to have any insight on how to do this?

Thanks in advance

AsyncSqlDataSourceProvider example

Tim — Tue, 14 May 2013 22:31:20 GMT

Hi, I think what I want to use is an AsyncSqlDataSourceProvider - but implementation is still fuzzy to me. It seems to me that the primary key is not the primary key of my database but the primary key of my results (presumably the filter results).

I have a database with several hundred thousand rows. I would like to use the ListBox search to search for a term, say 'apple', which will then return a result set via my database let's say 100 rows. Should these rows return a "primary key" that is 1 to 100 reflecting the results from the database? Or should I be using the original primary key? What if I pre-sort the rows in the db?

Update. In experimenting with this, I found, like all the other ones, that the grid seems to load data based on the primary key - so if I bring the data from the database not sorted by primary key but some other value, it will end up not being able to load the right items. As I scroll, it asks not for a "skip" value, which is what one would expect, but it inserts the equivalent of skip inside the filter, but with something like id < 5423.

Update2. Ok, I see the problem, I had to do some finagling on the index < ###. When CanSkip is off it looks like the expression has <= ### instead of < ### which appears to be the cause of my grief.

Bug in SearchTextBox

Tim — Wed, 15 May 2013 01:04:32 GMT

When I do a search (search box icon turns into X), then click on an item (search box turns blue), then click in the search box again, the search box shows both the magnifying glass and the X. I think it should be X as long as there is content in the SearchTextBox.

Update. I was working towards creating a separate Template for the SearchTextBox to clear this issue, but it ended up taking away the MetroLight style. Not sure why though.

Grouping doesn't update when a value in grouped-by column updates in a DataGrid bound to an binding list if property is one level down

mukesh — Wed, 15 May 2013 18:20:48 GMT

updated item is not getting grouped properly if updated property(ies) is one level down.

i.e. ConcreteTrade.IsLiveStatus

Please suggest if i m missing something.

SearchTextBox to search database instead of result set?

Tim — Tue, 14 May 2013 18:00:27 GMT

Hi, I would like to use the SearchTextBox to search my database instead of just filtering my result set. Is this possible? Or do I need to create a separate lookup box for this? How is it done in the NetFlix example?

Is there any way to reduce deployment size of Xceed DataGrid for WPF?

Mikhail — Tue, 14 May 2013 21:13:35 GMT

Hi,

I installed xceed datargid and liked its features. But our product requre as little deployment size as it is possible.

Do we have any ways to reduce deployment size of Xceed datagrid for WPF?

Currently it is about 3.3Mb grid + 0.16 Mb Controls = 3.56 that is too much, unfurtunately.

Thank you in advance!

ScrollBar scroll too fast -> An unexpected internal failure occurred in the Xceed Data Services module.

Tim — Wed, 15 May 2013 00:10:22 GMT

Hi, I have a listbox with about 5000 items from an AsyncSqlDataSourceProvider. If I just use the scroll wheel on my mouse, everything works great from the top to the bottom and back. However, if I use the scroll bar to quickly scroll down to the bottom, the Xceed Listbox crashes and I get the error. Any idea how I can catch this so it doesn't crash out of the program?

Failed to create a 'Path' from the text '(sllb:SearchTextBox.FilteredFieldNames)'

Tim — Tue, 14 May 2013 18:44:47 GMT

In case anyone else runs into this...

After creating a copy of the Xceed ListBox template in Blend 2012, I had the "Failed to create a 'Path'" error. Although the error shows up in the main control, it actually comes from the template. Look for

sllb:SearchTextBox.FilteredFieldNames="{Binding (sllb:SearchTextBox.FilteredFieldNames)....

and remove the parentheses around the binding. TooComplexText will also show up.

It does compile and run with these errors, but they are annoying to look at.

Cheers,

Tim

What is that saying? Life goes on?

Scrollbar choppiness

Tim — Tue, 14 May 2013 18:31:27 GMT

Hi when set to animate or even the default animation, the mouse scrollwheel works well. However if you use the mouse to move the scrollbar handle, it will animate but the scrollbar location will get stuck as it is animating, almost as if there is a process conflict. The location will get stuck until the animation completes, then it will jump to the final location. This is not the case when there is noanimation.

This same jumpiness happens when the ScrollViewer PanningMode is set and one tries to do a touch scroll.

Very small files downloaded "successfully", but empty

Leonard — Tue, 13 May 2008 22:10:52 GMT

Hello,

While evaluating the latest version of the FTP libary for .NET I came accross the following behaviour that can be simulated by following the steps down below. Please let me know if there's a fix available for this issue -

Problem: Very small files (1 - 2 charactes, or 4 bytes - for instance) are randomly downloaded empty, w/o errors being generated. The higher the connection speed to the FTP server, the higher the occurence rate. For an FTP server part of the LAN - we get about 15% of the files empty

How to reproduce the behaviour: (1) use a source FTP server with a high connection speed [I used FileZilla on a LAN server because I wanted to test implicit SSL]; (2) Have available on the FTP server several very small files, say 4 bytes each - we'll attempt to download them in a single session [I used 100 text files, each having just 2 characters as the body of the file] (3) download all these files locally, one at a time, by name - as part of the same session. You'll end up with about 15% of the files which are empty (size=0), and no errors raised on either end (server, or client).

Here's the code that I used to simulate the behaviour. Thanks for your help --

class TestConsole

{

static void Main(string[] args)

{

FtpClient ftpSession = new FtpClient();

ftpSession.TraceWriter = Console.Out;

ftpSession.CertificateReceived += new CertificateReceivedEventHandler(ftpSession_CertificateReceived);

int hostport = 990;

ftpSession.Connect("your FTPS Server IP address", hostport, AuthenticationMethod.Tls, VerificationFlags.None, null);

ftpSession.SendCustomCommand("PROT P");

ftpSession.Login("your user name", "your password");

ftpSession.ChangeCurrentFolder("upload");

ftpSession.ListingParsers.Clear();

ftpSession.ListingParsers.Add(new FtpUnixListingParser());

FtpItemInfoList items = ftpSession.GetFolderContents();

foreach (FtpItemInfo item in items)

{

if (item.Type == FtpItemType.File)

{

string dnloadRemoteName = item.Name + ".dload";

string dnloadLocalName = "c:\\temp\\" + dnloadRemoteName;

ftpSession.RenameFile(item.Name, dnloadRemoteName);

ftpSession.ReceiveFile(dnloadRemoteName, dnloadLocalName);

AbstractFile localFile = new DiskFile(dnloadLocalName);

if (localFile.Size > 0)

{

localFile.Name = localFile.Name + ".txt";

ftpSession.DeleteFile(dnloadRemoteName);

}

ftpSession.Disconnect();

ftpSession.CertificateReceived -= new CertificateReceivedEventHandler(ftpSession_CertificateReceived);

}

static void ftpSession_CertificateReceived(object sender, CertificateReceivedEventArgs e)

{

e.Action = VerificationAction.Accept;

}

Multi-touch support

ListBox for Touch

Linus — Thu, 29 Nov 2012 06:02:23 GMT

Hi I would like to know if the Xceed Ultimate ListBox for WPF is able to achieve touch panning on the listboxitems (not via the scrollbar) with elastic animation when it reaches the end of the list and have UI virtualization enabled?

thanks!

FillEffect's hatch style does look very different on OpenGL mode then on GDI mode

bogdip — Tue, 14 May 2013 13:17:41 GMT

Hi,

I'm using a Bar series and want to hash a bar with the LightDownwardDiagonal hatch. So I want my bars to look as hashed with thin gray lines.

It looks ok on GDI mode but we need the chart to be displayed in 3D also. And in 3D mode (OpenGL set) the LightDownwardDiagonal hatch looks differently, the lines are more tick and rare.In your demo application I see the same effect.

What can I do to hash the bars in the same way, in both GDI and OpenGL modes?

What is the best way of defining the header in an xml file and creating columns at runtime, instead of declaring it in the xaml?

---------------------------------------------------------------------------------------------------------------------------------------------------------------------

COL1 COL2 COL3 | GRP_COL1 GRP_COL2 GRP_COL3 | GRP_COL1 GRP_COL2 GRP_COL3 |

----------------------------------------------------------------------------------------------------------------------------------------------------------------------

void CreateGroupColumns()

{

for (int i = 0; i < 4; i++)

{

Xceed.Wpf.DataGrid.MergedColumn col = new Xceed.Wpf.DataGrid.MergedColumn();

col.Title = "Group"+(i+1);

Xceed.Wpf.DataGrid.ColumnBase col1 = new MyColumn("QTY");

col.ChildColumns.Add(col1);

Xceed.Wpf.DataGrid.ColumnBase col2 = new MyColumn("PERC");

col.ChildColumns.Add(col2);

Xceed.Wpf.DataGrid.ColumnBase col3 = new MyColumn("VAL");

col.ChildColumns.Add(col3);

GroupGrid.Columns.Add(col);

}

All items in ListBox expand to same size

Travis — Wed, 20 Jun 2012 18:28:02 GMT

I am using the Ultimate ListBox for WPF. I want to expand out an ItemsControl to show more information for the selected item, so I am using a selected and non-selected DataTemplate with a Style trigger setting the ContentTemplate when the row is selected. My problem is that once I select a row that has data to expand, the height of all of the ListBoxItems increases so they are all the same size. I need to be able to have non-selected items retain their original heights. It works perfectly with a regular ListBox, but has this issue with the Ultimate ListBox. Is there a way to accomplish this with the Ultimate ListBox?

Thanks,

Travis

Using AxisLabels

Contagion — Sat, 22 Apr 2006 01:53:55 GMT

I have a simple multiseries line chart and I've had no problem setting custom labels on my XAxis, however they're overlapping so I'd like to adjust the orientation of the text.
AxisLabel.Angle seems like what I should use, but I can't seem to get ahold of that object.

Can anybody point me to sample code (including in the ChartExplorer samples if I just somehow missed it in there) that can show me how to get ahold of an actual AxisLabel or AxisLabelCollection for either a custom Axis or the default X axis?

Hi,

I have gone through the basic examples, but I cannot find exactly what I'm looking for.

I have a Xceed grid, version 3.9.13165.12030, with columns for quantity and price.

When grouping the grid, I would like to show the average per group, for the (quantity * price) in the price column.

Is it possible to do this?

I've used ILMerge to merge the three assemblies Xceed.Wpf.DataGrid.v4.5.dll, Xceed.Wpf.Controls.v4.5.dll and Xceed.Wpf.DataGrid.ThemePack.1.v4.5.dll into a single assembly.

Does anyone know how to resolve this?

Permission Denied 70?

JAMES — Mon, 06 May 2013 09:27:19 GMT

Been using Xceed encryption on an Classic ASP system for a while now.

We have recently moved from a 2003 box to 2008 64bit. It is running in IIS 32bit mode. I think it is all setup correctly!

Since moving to the new server, things have been going fine apart from alot of "Permission Denied" error 70 when encrypting.

The encryption seems to be working fine - everything seems to be getting encrypted (eventually), so I am not sure why this error keeps popping up? Where is it having the permission denied?

I am getting concerned I have begun looking at other encryption components - but ideally would want to keep with what we have been using for years

Any ideas would be great..

James.

Master with different detail grids

Steve0212 — Fri, 01 Mar 2013 19:50:34 GMT

Is is possible to have one grid with multiple sections f different information. Consider this example where I am writing a search function. I search for "Bob". I would want the resultant grid to combine not just all the Bobs in the company, but also all the files Bob created.

I would want the grid to look something like this:

Users <-- Master Row

User Name Display Name Email Address <-- Detail Row

Files <-- Master Row

File Name Folder Location File Size <-- Detail Row

Is this possible?

Making 'non-enum' FilterCells have striped background like 'enum' FilterCells in a FilterRow

Neo — Mon, 19 Oct 2009 14:52:04 GMT

I've attached an example project demonstrating this. In my FilterRow, the columns based on enum properties of my datasource are disabled and appear with a striped background. I have set the IsEnabled flag to false on my other non-enum column FilterCell, but it doesn't show as disabled with a striped background like the enum column FilterCell does.

Is there any way of forcing this?

FilterCell doesn't work in this scenario

YiChen — Tue, 16 Apr 2013 07:38:01 GMT

Hi,

I have a dataGrid which is bond to a collection instances of Class A. Inside class A, there is a property called CompanyProp with type of Company Class. Company class is quite simple which only have a property called Name of string type.

I use FieldName="CompanyProp.Name" in Column settings and everything works fine, except the filtering. There is no responds no matter what I keyin in FilterCell of this column. I try to change to DisplayMemberBindingInfo to set Path, it also only work with display.

So how can I make FilterCell work with this kind of column without changing my Class A. ( I know if I create another string property to wrap around the CompanyProp and it will work. But I want to avoid to change my Model).

Thanks. Looking forward your reply.

Regards,

David

Deleting a row from the xceedgrid after sorting.

rupak — Mon, 15 Apr 2013 10:32:14 GMT

Hi ,

i want to delete a selected row after the user sorts the grid (say sort on the first column) . I am taking the selected index property to delete the item from the item source which is a data table. But the problem is since the items are sorted now ( only on the grid not in the underlying datatable) i am deleted the wrong item ( example : if the 5 th row is selected on the UI, it is not really the 5 th row of the data table; because the UI is sorted ).

How can i get the item source with the sorting expression applied on it; so that i can directly delete the selected item.

Dynamic row and column to xceed grid.

Hi ,

i have a requirement with below 3 features :

2. The user can add row /columns to the grid at any position ( like the excel insert row/column feature).

3. User should be able edit the data and the changes should be saved to database.

Really appreciate if someone share some sample code to arrive at point 1 and 2 .

Exception when pasting new items

From our perspective, we are binding to the ApplicationCommands.Paste command on the DataGridControl class. When items are pasted on the grid, our handler for this command is fired and we update our record collection, then switch to the dispatcher thread and do the following to update the grid with the new items

var binding = dataGridControl.GetBindingExpression(ItemsControl.ItemsSourceProperty);
if (binding != null)
{
binding.UpdateTarget();
}

Normally this all works fine, though it does get called a few times per paste. However randomly, when pasting a large number of items we get the exception seen above. It is not obvious from this exception whether it is coming from within the paste handler of the DataGridControl or handling the update of the ItemsSourceProperty.

Please could you shed some light on this exception and whether we are doing something wrong, which causes it.

Thanks.

Problem in binding Combox as CellEditor / setting SelectedValueProperty through C# code

Supriya — Tue, 01 Dec 2009 15:41:28 GMT

Hi..I am using Xceed DataGrid For WPF 3.5 professional edition.

I am binding a combobox as cell editor through C# code and not throgh XAML. The selected value of the combobox is not retained in the cell after the edit. I want to set the SelectedValueProperty so that it will retain the selected value, but dont know what should i set it to?

System.Windows.FrameworkElementFactory comboBox = new System.Windows.FrameworkElementFactory(typeof(Xceed.Wpf.Controls.NavigableComboBox));

comboBox.SetValue(Xceed.Wpf.Controls.NavigableComboBox.ItemsSourceProperty, columnInfo.DomainValues.DefaultView);

comboBox.SetValue(Xceed.Wpf.Controls.NavigableComboBox.DisplayMemberPathProperty, "DomainValue");

comboBox.SetValue(Xceed.Wpf.Controls.NavigableComboBox.SelectedValuePathProperty, "DomainID");

//comboBox.SetValue(Xceed.Wpf.Controls.NavigableComboBox.SelectedValueProperty, "Xceed.Wpf.DataGrid.CellEditorBinding"); ???

dataGrid.Columns[columnInfo.Code].CellEditor = new CellEditor();

dataGrid.Columns[columnInfo.Code].CellEditor.EditTemplate = new System.Windows.DataTemplate();

dataGrid.Columns[columnInfo.Code].CellEditor.EditTemplate.VisualTree = comboBox;

I have gone throgh lot of documentation and posts, but did not find 'what to set' in SelectedValueProperty, through C#. Please help.

Binding by ID

Filippo — Tue, 23 Apr 2013 08:12:55 GMT

Hi all,

I have the following situation. I am using a DataGrid to display a list of Boxes. Each Box has a ProductID property. I also have a list of Products, each of which has an ID and a Name.

I want to 1) display a product Name instead of the ProductID, and 2) allow the user to select a Product from a ComboBox in the CellEditor, and change Box.ProductID accordingly.

So far, I've been able to do #1 by using DisplayMemberBindingInfo with a Converter that turns ProductIDs into product names.

However, I'm stumped on #2. I've tried putting this in the cell editor template:

but it won't work, I think because at this point the source of the Binding of SelectedValue is not a Box, but rather a product name. So I've changed it to:

                                <ComboBox IsEditable="True" IsTextSearchEnabled="True" DisplayMemberPath="Name"
                                          ItemsSource="{Binding Client.Products, Source={x:Static local:App.Instance}}"
                                          SelectedValue="{xcdg:CellEditorBinding}"
                                          SelectedValuePath="Name"/>

This results in the ConvertBack method of my Converter getting called with the selected product name, which won't work either (as I can't map back from product names to product IDs).

I realised that using DisplayMemberBindingInfo with a Converter is probably not the right way to do this, as it means that in the CellEditor I'm stuck with a product name. But I can't figure out how to do it otherwise. Help?

Get subdirectory anywhere on drive

Cory — Wed, 24 Apr 2013 17:23:20 GMT

Is there a way to indicate a directory in FilesToProcess to get a directory of a specific name, but located anywhere on the hard drive?

For example, I can specify a file, like testfile.txt, and it will get copies of that filename in any subdirectory on the entire hard drive.

I have a directory with a particular name, but could be anywhere on the whole drive. I want to get the contents of that whole directory, no matter where it is on the drive.

Just plain "directoryname\*" only gets that directory at the root.

"*\directoryname\*" only gets the directory if it's one, and only one, subdirectory deep from the root.

I need something that would be equivalent of specifying all of this:

directoryname\*

*\directoryname\*

*\*\directoryname\*

*\*\*\directoryname\*

*\*\*\*\*\directoryname\*

ad infinitem...

GridControl.Rectangle.Width is fetching wrong value in Outlook.

Arnoj — Tue, 23 Apr 2013 11:01:06 GMT

We have an application that is a plug in to Microsoft Outlook. When we login to our home page inside the application, we have some columns that are displayed ( like "from", "to", "subject" etc.). Our problem is everytime we login to this page after opening Outlook the columns are shoved to extreme left. Expected behaviour should be the columns retain their previous sizes and are not shoved to left. Our app is fetching the window size of the Outlook using "GridControl.Rectangle.Width" of Xceed.Grid.dll. Is this a known problem in some scenario? If we replace the current Xceed.Grid.dll with newer version will it get solved? Where can I get a trial version of this dll for testing?

Ultra-Simple Grid breaks VS2010 designview

Sascha — Tue, 04 May 2010 19:49:19 GMT

Hi,

make a new WPF C# Project (no matter if .NET 3.5 or .NET4), put in xceed.wpf.datagrid (3.7.10175.16000) as reference and merge the following code into the mainwindow.xaml:

    <xcdg:DataGridControl>
        <xcdg:DataGridControl.Columns>
            <xcdg:Column FieldName="MessageNumber" IsMainColumn="True" MinWidth="0" Title="Nr" Width="50" />
        </xcdg:DataGridControl.Columns>
        <xcdg:DataGridControl.View>
            <Views:TableView>
                <Views:TableView.FixedHeaders>
                    <DataTemplate>
                        <xcdg:HierarchicalGroupByControl Views:TableView.CanScrollHorizontally="False" />
                    </DataTemplate>
                </Views:TableView.FixedHeaders>
            </Views:TableView>
        </xcdg:DataGridControl.View>
    </xcdg:DataGridControl>

You'll see that VS2010 designer will cease work with an System.Reflection.TargetInvocationException
The party-pooper is the HierarchicalGroupByControl.
I don't know why, but this code worked definately with older versions of xceed.datagrid.
You don't use your own grid in projects, I suppose?

Please post an solution - thanks.

Error while unloading form/exiting application (smartui2.ocx_unloaded)

Sebastian — Fri, 19 Apr 2013 07:40:00 GMT

Hi,

we get a random error when we try to terminate our application und unload the main mdi-form. On all forms (including the mdi-form) we use a menu and a toolbar (both with the smartui-component, latest version 2.0.0.8811).

The error occurs not always but mostly, both in the IDE and in the compiled program and also on different operating systems (Windows XP, Windows 2003 Server, Windows 7/8, 32 and 64-bit). When we exit our application on Windows XP we get randomly an exeption with "smartuishared" in the titlebar of the error-dialog.

The following errors are displayed:

memory leak with DataGridControl

Michael — Wed, 03 Apr 2013 15:19:10 GMT

Dear sirs,

using your DataGridControl for WPF (V. 4.2.11322.13590) I end up with a memory leak.

My profiler shows the root path down to the static GroupConfiguration.DefaultGroupConfiguration. That seems to prevent DataGridControl from being CGed. I dont know how to get rid of it.

Thanks for any help.

FilterRow filter event

YiChen — Wed, 03 Apr 2013 08:30:49 GMT

Hi,

We are using FilterRow in DataGridControl to do the customized filtering. But we cannot find any event that fired after user type in within filter cell and view is filtered.

How can we get equivalent event or is there any workaround to be informed after filtered by typing in FilterCell of FilterRow?

How to put a customized checkbox into the filterCell

YiChen — Wed, 03 Apr 2013 03:15:00 GMT

Hi,

I have a FilterRow for datagrid. And I want to put a customized checkbox into filterCell within the fitlerRow. I found this http://xceed.com/CS/forums/thread/26837.aspx . But it is not generic way. If I have multiple bool columns , then I need to define multiple filterCell. Is there any generic ways to do that?

Second question is if I use the way provided by that thread, I found the checkbox will only have two status (even I use WPF default checkBox), checked and unchecked. But the filter row's default checkbox have three status, checked , unchecked and no selection. How to make it have the same behavior as the default checkbox?

Regards,

David

DateTimePicker highlight style when lost focus

Toot — Sat, 30 Mar 2013 14:21:01 GMT

Hi, great library.

Example: User clicks into the month section of the DateTimePicker control (which highlights the month part), then clicks the updown spinner to move that selection up/down. When the user clicks the spinner, the textbox part loses focus and the highlighted chunk is no longer highlighted ... how can I make it retain the highlight?

Thanks very much for your time.

Bind DataGridCollectionViewSource to a Datatable in any page

Kieran — Wed, 06 Mar 2013 13:26:59 GMT

Hi,

In the getting started documentation you bind the DatagridCollectionViewSource to the Orders Datatable using the xaml:

Source="{Binding Source={x:Static Application.Current},

Path=Orders}"/>

I have the gird in a separate page and i was wondering what i replace Application.Current with to get the current page that the c# file is for?

To clarify i have the DataTable defined in the page and i just want to bind that that, instead of having to define it in the App.xaml.cs.

Thanks,

Kieran

Preventing change of SelectedItem in WinComboBox on Up/Down cursor presses

Peter — Fri, 29 Mar 2013 06:34:04 GMT

Hi,

I'm trying to prevent item changes in a combo box with the up and down arrow keys.

I have bound data to the combo box through a dataset.

I've set

.TextBoxArea.ReadOnly = true
.AllowFreeText = false
.AllowDropDown = false

And yet I can select the combo box and either use the arrow keys or press a letter on the keyboard (corresponding with the first letter of the item) to select another item.

I could just use .Enabled = false, but I prefer the alternative way as I can read the contents of the text box better.

Thanks,

Peter.

Any columnchooser fix for DataGridControl v3.8?

Jeff — Thu, 21 Mar 2013 19:52:38 GMT

We are using v3.8 of the WPF DataGridControl. Whenever we have custom theme in a TableView, the ColumnChooser will fail to display. From browsing the DataGrid forum, it seems this is a known issue that's fixed in v4.3:

http://xceed.com/pages/TopMenu/Downloads/Updates.aspx?ProductId=9aa44cb9-cf78-db11-9ed7-0015c5e239e6

We are wondering if there's a patch of this issue for v3.8? If not, is there any workaround you can suggest to us?

Thanks.

Issue Binding DynamicObject properties to StatCells

Nathan — Fri, 27 Jul 2012 16:10:19 GMT

I have a data source that I convert into a list of view objects that have dynamic properties. My view objects inherit DynamicObject, allowing me to create the needed columns at runtime. I allow the DataGridCollectionViewSource to generate it's own ItemProperties. I then manually generate the column definitions on the actual data grid. All the bindings work great until I started adding stats rows.

I added a SumFunction to the DataGridCollectionViewSource, and a StatCell to the datagrid footer. When I run it, I get the following error:

System.Windows.Data Error: 17 : Cannot get 'SumOfCustomerTotal' value (type 'Object') from '(0)' (type 'DataGridCollectionViewGroupRoot'). BindingExpression:Path=(0).SumOfCustomerTotal; DataItem='StatCell' (Name=''); target element is 'StatCell' (Name=''); target property is 'Content' (type 'Object') InvalidSourcePropertyNameException:'Xceed.Wpf.DataGrid.Stats.InvalidSourcePropertyNameException: 'Total' is not a valid field name.

"Total" is a valid dynamic field, that is correctly populated on the grid, but the StatCell appears to have issues binding to it. I tried defining that column in my view object in code, and it worked. Problem is, I can't do that because most of my columns are determined at runtime by the data coming in. Any ideas how to solve this?

SmartUI Windows 7 compatibility.

Adam — Tue, 26 Mar 2013 21:03:48 GMT

One of the applications I am maintaining was written using Visual Studio 2005 and as such is a .Nst 2.0 application. It is using Xceed SmartUI 3.3.3031 to place a SmartCheckedListBox on a form.

One of our users who has been upgraded to Windows 7 is no longer able to select the checkboxes on this form. They actually do not even appear. They can select an individual item, but more than one is no longer available.

Is there a configuration issue, application or system setting, or bug involved in this? Is it simply a matter of that version not being compatible with windows 7 and we need to purchase an upgrade?

Thanks,
Adam

How to set DefaultCellEditors in Style

YiChen — Wed, 27 Mar 2013 02:20:07 GMT

Hi,

I want to have a default bool editor template in xceedgrid for edit mode. I know it can be done by set in view by using DefaultCellEditors. But I want to set DefaultCellEditors in style of DataGridControl but unfortunately I found that DefaultCellEditors is a readonly dependency property, which cannot set in setter of style.

So how can I achieve that in style?

Looking forward your reply.

Is SFtp for .NET equal to FTP for .NET plus SSH (SFTP) capabilities?

Bruce — Thu, 07 Mar 2013 16:53:24 GMT

I have a present need for FTP with SSL, which the standard FTP for .NET will handle. I may have a future need for FTP with SSH.

The product features tab for SFtp for .NET looks like it supports both SSH (SFTP) and SSL (FTPS). Is this correct? If the SFTP library handles both, it will most likely be worth spending the extra $100 for the extra capabilities, even if I don't need them right now.

Thanks

Robin — Tue, 26 Mar 2013 10:16:34 GMT

I am creating a .NET version of a VB6 component we have and as part of that I need to extract individual PDF files from an encrypted archive. I have written a function to do so (see below). The password supplied to the function is correct and valid as it can be used to extract the PDF file from the archive using WinZip. however I am getting an error 'The decryption password is invalid', is there something wrong with the code below?

Hide Group Level Indicator Panel

Ricardo — Thu, 16 Aug 2007 14:25:33 GMT

Hi all,
I´m kinda new to XAML, maybe i´m doing something wrong.
I don´t want to use the Header in which is written Drag a Column header here...

So i´m doing the folowing:

<xcdg:DataGridControl x:Name="dtgDados">
<xcdg:DataGridControl.Resources>
<Style TargetType="{x:Type xcdg:GroupLevelIndicatorPane}">
<Setter Property="Visibility" Value="Collapsed" />
<Setter Property="ShowIndicators" Value="False" />
</Style>
<Style TargetType="{x:Type xcdg:TableView}">
<Setter Property="Theme" Value="Aero.NormalColor" />
<Setter Property="ShowRowSelectorPane" Value="False" />
</Style>
</xcdg:DataGridControl.Resources>

</xcdg:DataGridControl>

The styles for the TableView are working ok, but the GroupLevelIndicatorPanel is still appearing. How do I make it disappear?

I´m doing the databind in C# codebehind.
For that i´m using the ItemsSource property of the DataGrid.

Thanks for now.

Unzipping to memory only gives blocks of 1024 bytes

Viggo — Mon, 18 Mar 2013 23:14:24 GMT

Greetings,

I am new to the Xceed compression library and not able to figure out why unZipping to memory only gives 1024 bytes per callback event.

In the XM_UNZIPPREPROCESSINGFILE event I set xDestination to xudMemory and according to the docs the complete data should be passed on the first XM_UNZIPPINGMEMORYFILE event.

The docs at http://doc.xceedsoft.com/products/XceedZip/UnzipPreprocessingFile_event.html states:

"Setting this parameter to xudMemory (1) will cause the file to be unzipped to memory via the UnzippingMemoryFile event. The entire file's uncompressed data will be provided through a single occurrence of the UnzipPreprocessingFile event in this case."

I must have overlooked or misunderstood something but not able to circle in what. Any suggestions where to look?

Thanks in advance!

Kind regards
Viggo

Increase the "timeout" for FtpClient.GetFolderContents()

ganders — Thu, 28 Feb 2013 20:48:46 GMT

The directory that I'm executing this method on contains over 100K (100,000) files. It times-out while iterating over all of these files. I've updated my FtpClient.Timeout setting to 2 hours, but my job is still failing after ~900 seconds. Is there a different timeout property that I need to set, or do I need to set a KeepAliveInterval or something like that in order for this to continue iterating over the files in my directory?

Here's my stack trace information:

How can I retrieve filtered data after filtering

YiChen — Sun, 17 Mar 2013 14:02:27 GMT

Hi,

I am using Xceed DataGridControl. I cannot find a correct event to get filtered data. I know there are AutoFilterValuesChanged and Filter events in DataGridCollectionViewSource. But it seems it is fired before actually filtering.

So how can I get data after it is filtered?

Looking forwards your reply.

[Bug] If the DataGridControl is under another Tab, unable to select the newly added row by clicking the CurrentItem

Sam — Tue, 19 Mar 2013 15:14:40 GMT

Problem Description:

1. Under a <TabControl>, the DataGridControl is in one of the hidden <TabItem>.

2. It is bind to a DataGridCollectionViewSource then a ObservableCollection. Initially there is no item. Item is added while the Grid is still hidden.

3. Select the Tab where the Grid is in.

4. The DataGridControl.CurrentItem is set to the oldest item. However, the SelectedItem is null. Clicking or press space on that row does NOT select the item. Clicking other row will do. And after clicking any other row, that 1st item is also selectable.

Expected Result:
On step 4 - the CurrentItem (the 1st item) should be selectable by clicking, without clicking any other row first.

Here are the Repro XAML and CS:

Steps - 1. Click the Add button for a few time. 2. Switch to the 2nd Tab. 3. Found that the first item is not selectable by clicking

Aborting a transfer sometimes hangs the ActiveX

Alex — Sat, 09 Mar 2013 21:27:53 GMT

Hello,

We're using the library for a little upload utility in our software as well as the basis for a full FTP client. In both cases we have big issues aborting transfers. This does not happen every time, but it's pretty frequent that when setting the "Abort" property of the ActiveX, the "SendFile" function will just hang and never return.

Once this happens, we pretty much can't do anything other than close the app and restart... Sometimes, setting "Abort" to true several times will make it unlock, but most of the time it has no effect. If we call anything on the ActiveX at this point we get an exception that says the ActiveX is already performing a call.

Any idea? I just downloaded the latest update for the ActiveX version and the issue is the same.

Format string cell as number

Leo — Tue, 19 Mar 2013 19:10:53 GMT

I've been trying to figure out a way to certain cells in a string column as a number. I have my grid setup as all string columns since I have different types of data throughout the grid. Currently, I'm running into issues of rounding problems as the formatted numbers need to have no decimals but the decimals need to be calculated in certain totals. I have the underlying data and can do it in the background but other grids reference this grid as well so while I can use the underlying data, which may be the better way to do this, I'm also on a time crunch so if there's a simpler solution with less impact to the total project, I'll take that for now.

Can anyone point me in the right direction? Basically, I have a string cell and I'd like to show the underlying value as one format but keep the true value available in the cell.

Thanks!

ecaterina — Wed, 11 Feb 2009 18:53:03 GMT

Hello,

Several days ago we migrated our solution to 3.1 version of xceed datagridcontrol.

Everithing goes fine, except one case : My DataGridControl on page has this property setted:

Visibility="{Binding Path=IsSelectedSplit, Converter={StaticResource BB}}" and on build everything goes fine, but when I acces that window I get the following exception :

Inner Exception : Object reference not set to an instance of an object.

Adding rows with DataGridVirtualizingCollectionView

Loic — Fri, 15 Mar 2013 10:42:54 GMT

Hi,

I use a WPF datagrid with collection virtualization enabled (DataGridVirtualizingCollectionView).

When I want to displaying my chunk of rows with QueryItemsEventArgs.AsyncQueryInfo.EndQuery, the grid will show for 1 or 2 seconds empty rows (with default value, image,etc.). Did I miss something or it's the normal behavior of the grid ?

Second point. I want to add a new item in my grid. Right now, I invoke the Refresh method of my DataGridVirtualizingCollectionView which cause a new blink. Is there another method to add a single row (and by extension, to remove one row) ?

Thanks.

Loic

HasValidationError is True after removing invalid row

Mario — Thu, 14 Mar 2013 15:52:31 GMT

I modified the Validation sample so the grid property IsDeleteCommandEnabled is true. I also added a ListChanged event handler on the MainPage so I can inspect the HasValidationError property. When I delete the invalid row while running the sample app the HasValidationError property remains True.

Is this the expected behavior?

I am using version 4.3.12355.10260

Filtering Bars

Maree — Thu, 14 Mar 2013 01:27:20 GMT

I have been having an issue where I want to graph approximately 7000 bars, however Xceed seems to automatically filter the bars and won't display them all. Is there a way to turn this off and have bars overlapping or is there another option for displaying all the bars? Thanks

Getting Cell value of selected Row.

Rocky — Sat, 09 Mar 2013 19:21:09 GMT

Hi there,

I have displayed data in Xceed Data Grid via DataTable.

DataTable dt = getProfile();

gridView2.ItemsSource = new DataGridCollectionView(dt.DefaultView);

I dont want user to make edit the data in the xceed datagrid itself but rather make edit in another window or popup. There is a Column named ID that is unique to each row in the datagrid and the database also so I need the cell value of selected row in another button click event or double click event of grid will also do.

I want to do something like this.

int id = gridView2.SelectedRow.Cells["ID"].Value;

Thanks

want some examples for using Xceed Binary Encoding Library

Bala — Fri, 20 Jun 2008 13:41:07 GMT

Hey,

I’m using Xceed Binary Encoding Library 1.1, to encode a Macintosh file to HQX format before sharing it through Email. I have a MAC file which has got the DataFork and resource fork as different streams in the same file(AppleShare File). I am able to encode the file, retaining the datafork and resouce fork. But still the type and creator is lost. I found few properties to be set before calling the Processfile method for encoding. The properties are

encodingFormat.HeaderCreator

encodingFormat.HeaderType

encodingFormat.HeaderFlags

I found no documentation to set these properties. When i try to set these properties there is a error as below

Property, indexer, or event 'HeaderCreator' is not supported by the language; try directly calling accessor methods 'XceedBinaryEncodingLib.XceedBinHexEncodingFormatClass.get_HeaderCreator()' or 'XceedBinaryEncodingLib.XceedBinHexEncodingFormatClass.set_HeaderCreator(ref object)'

and it fails to compile. I want some help on how to identify the Creator and Type from the <fileName>:AFP_Afpinfo stream and set it in these properties. If you provide some code to set these properties in C# it would be very helpful.

Thanks,

Bala Rajesh.

Xceed DataGrid_SelectionChanged event firing twice

Steven — Mon, 11 Mar 2013 16:24:54 GMT

I have a datagrid that fires the event twice. The goal is to get it to update the ItemsSource of two other grids inside a tab control. However, that event fires twice and the visible tab's grid doesn't update. Has anyone seen this before?

Thanks in advance,

Is there a way to allow grid sort only when clicking on the headers (and not when the data is changed) ?

Elad — Thu, 07 Mar 2013 10:49:19 GMT

I have a DataGrid with AllowSort=True in which one of the columns is a checkbox.

When the user click on the checkbox column header - the grid is being sorted properly, but when I click on the checkbox of one the data rows and change its value - the row is being moved to a different place because the sort is being applied.

Is there a way to apply the sort only when user is clicking on the column header?

Thanks,

Elad.

How to Set MinValue and MaxValue in XAML for a ValueRangeTextBox

Pierre — Tue, 05 Mar 2013 02:08:25 GMT

How do you specify in XAML the MinValue and MaxValue of a ValueRangeTextBox ? The following code does not work:

<Window

HorizontalAlignment="Left"

Margin="87,42,0,0"

Name="valueRangeTextBox1"

VerticalAlignment="Top"

Width="120"

ValueDataType="my:Int32"

Text=""

MaxValue="100"/>

</Grid>

</Window>

For MinValue and MaxValue I get the error: The value is not of type Int32

WinDatePicker Windows 7 Out of memory exception

Comodo — Mon, 04 Mar 2013 07:30:37 GMT

Good day.

I'm using Xceed.Editors version 2.5.12556.9330 on Windows 7 Professional Service Pack 1.

Using a short date of ddMMMyy (note no spaces) on the Windows OS "Customize Format" window, "Date" tab causes an Out of memory exception when using a WinDatePicker control. Re-create the problem by simply placing the control on a form, change the windows format and run the application.

Is this a known issue?

Hello,

We are getting the following error when closing ZIP file opened with Xceed. We are on an old 3.5.7573.12150 version and we are wondering if this problem has been fixed since then? If so, is there a bug/fix report we can take a look at and verify that this is the same problem?

Visual Studio 2012 XCeed Controls Integration

Enrico — Tue, 05 Feb 2013 10:21:53 GMT

Goodmorning,

yesterday i've bought the full version of xceed ultimate suite and now i've started using it for my job.

I have a simple question for you, why xceed controls don't show up in the toolbox in VS2012 like they did in VS2010?

I'd really need to have them separate by library like the old visual studio had :/

Any idea, suggestion or solution?

I've attached how I see the toolbox in VS2010 (and how I would like to see it in VS2012).

Thanks in advance,

Enrico.

P.s: Another simple question, now that i've updated all the packages, may I uninstall the old ones (like Xceed Extended WPF Toolkit plus 1.8) ?

Does Xceed use industry standard compression algorithms ?

Sysadmin — Tue, 20 May 2008 22:44:31 GMT

Objective:
Uncompress the data on the linux server. The data was compressed on a windows server using the default compression algorithm of "xceed zip verion 4.2"

Things noticed:
The compressed data always begins with the hex code: 00 33 30 30 32 37

Things tried:
1. Running the xcced DLL using wine on linux.
2. Posting in the newsgroup at: http://groups.google.com/group/comp.compression/browse_thread/thread/c840937f624ae8dd

Sample compressed data:
1. Binary representation

http://www.debt...care.com/rnd/zip/compressedpacket.5.txt
2. Hex Representation

Custom Group Header

Rick — Thu, 08 May 2008 19:01:09 GMT

Ok, so I have a list of Person objects in my datagridcontrol.

I want to group by PersonTypeID(because sorting by an integer is MUCH faster than sorting by a string) but I want to display the associated PersonTypeName inside the group header.

Is there any way to accomplish this?

Thanks so much for the help
