Dynamically changing properties of a cell editor

Matthew — Wed, 14 Oct 2009 22:21:45 GMT

I have a requirement to be able to change the value of the MaxLength property of a cell editor at run time. When a column's cell editor is the AutoSelectTextBox, our spec says the MaxLength may be changed under certain business rules.

It makes sense to me that one might bind the MaxLength property to an object that holds the current maximum length, but whenever I try this the cell's do not update their maximum length when the bound object changes. How should I go about this?

Is Custom Control allowed as the Xceed DataGrid Column as CellEditor in Xceed DataGrid?

paras — Thu, 03 Sep 2009 12:57:56 GMT

Hello,

I am using the Custom Control in the Exceed Data Grid as CellEditor in one of the Column. Now i am getting the custom control when the cell/column is in the Edit Mode. Now when i am selecting a value from the Custom Control. Its value is being selected but the column/Cell is not reflected with the Selected value.

<Window.Resources>
        <xcdg:CellEditor x:Key="categoryEditor">
            <xcdg:CellEditor.EditTemplate>
                <DataTemplate>
                      <ComboBox BorderThickness="0"
                            MinHeight="22"
                            VerticalContentAlignment="Top"
                            SelectedValue="{xcdg:CellEditorBinding}"
                            FocusVisualStyle="{x:Null}">
                        <ComboBox.Resources>
                            <Style TargetType="Popup">
                                <Setter Property="TextElement.Foreground"
                                   Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}" />
                            </Style>
                        </ComboBox.Resources>
                        <s:String>A</s:String>
                        <s:String>R</s:String>
                    </ComboBox>
                </DataTemplate>
            </xcdg:CellEditor.EditTemplate>
        </xcdg:CellEditor>
        <xcdg:CellEditor x:Key="ucCategoyrEditor">
            <xcdg:CellEditor.EditTemplate>
                <DataTemplate>
                    <common:ucEnhanceControl x:Name="ucCategory"
                                             MyText="{xcdg:CellEditorBinding}"
                                             Loaded="ucEnhanceControl_Loaded"
                                             FocusVisualStyle="{x:Null}">

                    </common:ucEnhanceControl>
                </DataTemplate>
            </xcdg:CellEditor.EditTemplate>
        </xcdg:CellEditor>
    </Window.Resources>

<xcdg:DataGridControl Name="dgcListView" AutoCreateColumns="False" ItemScrollingBehavior="Immediate" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="3" >
            <xcdg:DataGridControl.Columns>
                <xcdg:Column FieldName="Status" Title="Status" CellEditor="{StaticResource categoryEditor}"/>
                
                <xcdg:Column FieldName="Entity Category" Title="Entity Category" CellEditor="{StaticResource ucCategoyrEditor}"/>
            </xcdg:DataGridControl.Columns>
        </xcdg:DataGridControl>

Now, here for the Column Name="Entity Category", i m using custom control for the editing and cell editor is defined in the resource file which is fine but MyText="{xcdg:CellEditorBinding}" is not working although my MyText property which is also dependency property in the Custom Control which i am binding with the xcdg:CellEditorBinding.

So, Kindly reply me for the same. Kindly answer me for the same. As how to use the Custom Control in the Xceed Grid as the Cell Editor on how to bind the values with the Cell ?

Using value of one column in celleditor of another column.

priyanka — Thu, 25 Jun 2009 12:00:32 GMT

Hi,

I have two columns in my DataGridControl, lets say User Name and Role which are part of my Observable collection. The User Name column has a CellEditor which consist of a textBox and an Image. The requirement is to show the image as per role (the second column), that is an Admin Image or General User Image while editing the name. I am using an image converter however could not provide exact binding to it. Please guide me how to solve this purpose. I mean, I want some thing like following in cellEditor:

<xcdg:CellEditor x:Key="UserNameEditor">
                            <xcdg:CellEditor.EditTemplate>
                                <DataTemplate >
                                    <Grid>
                                        <Grid.ColumnDefinitions>
                                            <ColumnDefinition/>
                                            <ColumnDefinition Width="Auto"/>
                                        </Grid.ColumnDefinitions>
                                        <TextBox Grid.Column="0" Text=="{xcdg:CellEditorBinding}" />
                                        <Image Grid.Column="1"
                                               Source="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type xcdg:DataGridControl}}, Path=Parent.Children[1].Content, Converter={StaticResource imageconverter}}" />

</Grid></DataTemplate></xcdg:CellEditor.EditTemplate></xcdg:CellEditor>

I am using this cell editor in the following way in my DataGridControl.Columns:

<xcdg:Column FieldName="UserName" Title="UserName" Visible="True"
CellEditorDisplayConditions="CellIsCurrent"
CellEditor="{StaticResource UserNameEditor}">
</xcdg:Column>

Please let me know if more details are required.

Thanks in Advance :)

Binding values from one column to another

Viktor — Wed, 24 Jun 2009 13:56:07 GMT

How to I Binding values from one column to another with using DataTemplate? In C#, not in XAML.

Code:

private void GenerateDataTemplates(int ColumnNumber)
{
    var dt = new DataTemplate();

    var spOuterFactory = new FrameworkElementFactory(typeof(StackPanel));
    spOuterFactory.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal);
    spOuterFactory.SetValue(MarginProperty, new Thickness(10));

    var textBlock1 = new FrameworkElementFactory(typeof(TextBlock));
    var binding1 = new Binding();
    binding1.RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor, typeof (Row), 1);
    binding1.Path = new PropertyPath(string.Format("Cells[\"{0}\"].Content", dgTemplate.Columns[ColumnNumber].FieldName));//, new object[] {});
    textBlock1.SetBinding(TextBlock.TextProperty, binding1);

    textBlock1.SetValue(TextBlock.ForegroundProperty, Brushes.Black);
    spOuterFactory.AppendChild(textBlock1);

    dt.VisualTree = spOuterFactory;

    dgTemplate.Columns[ColumnNumber].CellContentTemplate = dt;

File browser in the cells?

Andreas — Sun, 31 May 2009 04:30:17 GMT

Hi,

I want to store file paths in one of my columns. I would like to include a Browse button so the user can browse the harddrive for the file rather than manually typing the path.

Is this possible?

Thanks,

Andreas

DataGrid not entering edit mode

Amir — Thu, 28 May 2009 10:43:07 GMT

I have a DataGrid with a few columns. I do not set the ReadOnly property for the grid or for any columns and while in runtime I can see that the column with the CellEditor ReadOnly property value is False.

However I cannot see the ComboBox im supposed to with the CellEditor. I was worried that maybe some style from controls up in the logical tree might be affecting this so i set "empty" styles for all types just in case but this did not work.

Im including the xaml and I hope you can point out anything that might be wrong or weird. I also wanted to ask if you can point out generally what might be the things that might affect the display of a CellEditor or prevent the DataGrid from entering edit mode.

One more thing. In the grid when I go over a Cell and hit F2 I do see the Row Selector Pane switch to the editting glyph however the CellEditor does not appear.

Here is the xaml, the code behind contains nothing special:

<UserControl.Resources>
<ResourceDictionary>

<xcdg:DataGridCollectionViewSource x:Key="ContractTables" Source="{Binding Path=TableReferences}"/>
<Style TargetType="{x:Type xcdg:DataRow}">

</Style>
<Style TargetType="{x:Type xcdg:DataGrid}">

            </Style>

            <Style TargetType="{x:Type xcdg:Column}">

            </Style>

            <Style TargetType="{x:Type xcdg:DataCell}">

            </Style>

        </ResourceDictionary>
    </UserControl.Resources>
    <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Margin="5">
        <StackPanel>

Capturing Click event of Button in a DataCell using MVVM

Shailesh — Mon, 23 Mar 2009 19:42:43 GMT

Hello,

I am using Model View ViewModel pattern. I have a button inside a DataCell of Xceed DataGrid. I want to use DelegateCommand to handle the click event of the button.

Also, I dont want to write anything for the same in my Code Behind. I want everything to reside in my ViewModel.

How can this be achieved. I thought of RoutedEvents / RoutedCommands but they need some entry in the Code Behind file.

This I want to eliminate.

Requesting you to please help on the same.

Thanks and Regards

WPF Grid CheckBox behavior

Igor — Thu, 05 Mar 2009 13:09:12 GMT

Hi !

I have strange behavior of CheckBox columns of WPF Grid 3.1 (the latest version fron 17 February 2009).

There is small application, with TabControl of two tabs. The first tab control contains Xceed WPF grid control. The first column bind to some boolean variable. The problem occures then I check the CheckBox, than do not move to any other place in grid, just click on other tab item. When I return to the previous tab I see CheckBox still checked, but my variable restored to it's previous state. But if I'll move to another row of the grid after checking the checkbox everithing works fine.

My grid defined with UpdateSourceTrigger="CellContentChanged".

Please, help me to solve this problem.

Thanks!

Igor.
