How to keep shadow of the header follow the mouse?

Jia — Thu, 21 Jun 2012 07:56:45 GMT

Hi,

I am just update my xceed version to 4.3 now. However, I met the issue after that.

I integrated the data grid to one windowsForm project.

Then I drag the column header and want to group the values.

The shadow of the column header does not follow my mouse.

How to change it to let the shadow follows my mouse all the time?

Updating just the part of datagrid bound with xml

Kunal — Mon, 10 Oct 2011 17:43:15 GMT

Hi,

I am quite new to the xceed wpf datagrid and this problem is quite crucial for me. So please help!!!!

My grid is bound to a xml. Whenever i update the grid, i send a message to the server and i get a new xml from the server, to which i need to bind my grid to.

In my project about 100 rows are created on the screen, of which only 10 are visible on the screen at a time, Let's say the user is now on rows 40 -50 and makes a change on 45th row. Now, how is it possible that only 45th row gets updated and the whole screen is not refreshed.

How can i bind the grid's itemsource to just the xml node having changed value.

Thanks

Not able to update after binding with xml

Kunal — Thu, 06 Oct 2011 18:14:26 GMT

I have a datagridcontrol which i bind to xml. But don't know why, i am not able to edit it once i bind it to xml. I was able to edit it and it worked fine if i used datagridcollectionview. Does any one of you have any idea as to whats wrong.

I want to bind the grid with the xml which i get from the server. Once the user updates something on the grid..i send a string back to the server...which fetched me another xml to be ind with the same grid.

Also, i am doing everything code behind. I just have datagridcontrol in my xaml (page).

Can any body pls guide me as to what to do....if i am on the 15th row, i don;t want the whole grid to refresh and take me back to the first row.

Thanks

CellFiltering disabled

Moon — Fri, 12 Aug 2011 11:11:00 GMT

hello,

I have the following issue with grid filtering :

I can not make filtering on some columns, these colum are binded to complex field of my dataObject.

e.g :

MyDataobject :

string name
MyDataObjectType type

in the xaml :

<xcdg:Column FieldName="Name">

<xcdg:Column FieldName="type.typeName">

...

the filtering works good on column "Name" but is disabled on the other !!

how can i resolve this ?

Adding an Activation Gesture when using AutoGenerateColumns

Anderson — Mon, 01 Aug 2011 19:09:16 GMT

I have a table whose columns are dynamic. Essentially, we allow a user to create a table through a user interface. Once that table is created, we are using the Xceed datagrid to allow them to input values into the table they created. We are binding a DataTable representation of what the user creates to the datagrid.

We use AutoGenerateColumns for two main reasons. The first is we cannot predict the type of columns or even how many the user will create. The second is using AutoGenerateColumns allows the datagrid to figure out what editor to use depending on the value type in the ItemsSource.

The issue I'm having is when the page loads, I attempt to add KeyActivationGestures to each column in the datagrid in code behind. Unfortunately, this approach is not working. I receive the following error when trying to add the gesture to the current CellEditor for the column:

System.InvalidOperationException: Specified value of type 'Xceed.Wpf.DataGrid.ActivationGestureCollection' must have IsFrozen set to false to modify at System.Windows.Freezable.WritePreamble() at System.Windows.FreezableCollection`1.AddHelper(T value) ...

I have found posts on here about a similar topic but I am using the methods outlined in the posts. So I'm not sure what's going on with my approach.

Below is the code I am using in the Load event:

foreach (var col in valuesDataGrid.Columns)

{

var activationGesture = new KeyActivationGesture();

activationGesture.Key = System.Windows.Input.Key.F4;

col.CellEditor.ActivationGestures.Add(activationGesture);

activationGesture = new KeyActivationGesture();

activationGesture.Key = System.Windows.Input.Key.Space;

col.CellEditor.ActivationGestures.Add(activationGesture);

}

I looked at the ActivationGestures collection and IsFrozen is a getter only, the same goes for the IsFrozen property of the KeyActivationGesture object. Anyone have any suggestions?

How do I programmatically create totals at runtime when columns or field names vary dynamically depending on user request ?

Richard — Fri, 17 Dec 2010 19:16:59 GMT

Am new to XCeed Wpf DataGrid and I like everything I've tried so far....

I read most of the posts which shows it done in XAML and also saw the post about constructing XAML on fly (which seems messy).

My dataset isn't known until runtime so I don't have a way to set it properly on the DataGridCollectionViewSource in XAML. Tried exposing a DataGridCollectionView from code behind but it difficult since XAML wants to use the no-arg constructor and in code there doesn't seem to be a way to reset the Source property at runtime ? Plus the DataGridCollectionView class is sealed so I can't inherit from it.

Is there a way to fetch the DataGridCollectionViewSource from the grid at runtime, then in code behind reset the source and apply stat functions/rows ?

I need to apply totals on all numeric fields brought in as a result of a query.

We used Syncfusion grid in WinForms and this was easy to do since the Grid control itself exposed methods to do this at runtime.

Thanks very much,

Rich

Re make fixed Column Splitter "fixed" when reordering columns

Harish — Thu, 16 Dec 2010 19:42:20 GMT

Hi,

I am trying to find a way to make the fixed column splitter stay fixed at the declared column count. Currently, if the FixedColumnCount is four, it works fine as long the user doesn't drag one of the columns out of into the first four columns. But once that happens the splitter sticks and moves with the last column and no longer stays at the fixed column count.

Is there a way maybe by capturing the column reorder event if any to change the fixed column splitter to stay at the first four columns even when columns are being re-ordered and moved in and out? I tried various ways but didnt work (like adding a visible column index changed event through a dependency property and then setting the fixedcolumncount = 4 there but even though the code hit that statement nothing happened.

FYI, I have the full professional WPF grid version 4.1.

Thanks,

Harish

Excel like auto filtering in xceed data grid

Girish — Wed, 24 Nov 2010 11:41:27 GMT

We require Excel like auto filtering. (Including distinct value check boxes and filtering using logical operators like OR, AND, NOT, CONTAINS, IN, STARTSWITH, ISEQUALTO, ISNOTEQUALTO). Currently xceed datagrid doesn't support filtering based on logical operations. Is anybody have solution for this limitation?
