[Solved] Styling Filtering Controls

[Sherwin]

 Is there any way I can edit the style of the default filtering controls?

I'm using Silverlight 4 and telerik V.2011.1.419.1040.

Hello Sherwin,

 Yes, you may edit the style of the Filtering control. In order to do this you should edit the template of the FilteringControl.

<Style x:Key="ss" TargetType="{x:Type telerik:FilteringControl}" >
...
<ListBox x:Name="PART_DistinctValuesList" ItemsSource="{Binding DistinctValues}" ScrollViewer.HorizontalScrollBarVisibility="Auto" MaxHeight="100" SelectionMode="Multiple">
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox Content="{Binding ConvertedValue}" IsChecked="{Binding IsActive, Mode=TwoWay}" VerticalContentAlignment="Center">                <telerik:StyleManager.Theme>                                  <telerik:Office_BlackTheme/>                             </telerik:StyleManager.Theme>          </CheckBox>
</DataTemplate>
</ListBox.ItemTemplate>
<telerik:StyleManager.Theme>
<telerik:Office_BlackTheme/>
</telerik:StyleManager.Theme>
</ListBox>
...

Then you may apply this style to a specific column like so:

<telerik:GridViewDataColumn FilteringControlStyle="{StaticResource changedFilteringStyle}" DataMemberBinding="{Binding LastName}"/>

However there is something special. There is a control 'StringFilterEditor', which is responsible for displaying editors based on the type of the underlying property. You may access this control through subscribing the RadGridView's FieldFilterEditorCreated event and set the theme for the editor from there.:

Copy Code

private void grid_FieldFilterEditorCreated(object sender, Telerik.Windows.Controls.GridView.EditorCreatedEventArgs e)

       {

           if (e.Editor is RadDateTimePicker)

           {

               StyleManager.SetTheme((e.Editor as RadDateTimePicker), new Office_BlackTheme());

           }

       }




I hope that this is helpful. Please let me know in case you have any further questions.
