Custom Filtering Control

[Rayne]

I've created my own Filtering Control (class derived from FilteringControl) so that I can set a default FilterOperator to something other than Equal To. It works great, but it's using the default theme. My application uses the Office Blue theme, not the default Black theme. How do I get it to use the application's theme instead of the default?

I'm defining my class as a resource for the grid, then using it as a static resource for the column I want to change. Here is the related code for my grid:

<telerik:RadGridView.Resources>
     <common:ChangedFilteringControl x:Key="StartsWithFilterControl" DefaultFilter="StartsWith" />
</telerik:RadGridView.Resources>
.....
<telerik:GridViewDataColumn DataMemberBinding="{Binding Number}" FilteringControl="{StaticResource StartsWithFilterControl}" />

I'm guessing I need to apply a style but it's just not working.

Hi Rayne,

 I have prepared an example project for you that illustrates how to achieve this. It is attached for your reference.

All the best,

Thank you. The sample you attached does not contain the filtering control class.

I guess I didn't look close enough...I didn't realize the custom filtering control was defined in MainWindow.xaml.cs.
It worked. Thanks again!
