Hello,
I have telerik version 2014.1.331.40. I want to make a ComboBox filter in FilterRow mode in the RadGridView control. I need it to work exactly like the Textbox does, only with the ComboBox instead. I tried editing the control template of StringFilterEditor, but then I lose all functionality and when I try to bind the DisplayMemberPath, it doesn't work or when it does through code behind, it is very slow while I type what I want to Filter (I need to do Filter as you type which I did with the Textbox) (I use a large amount of Data).
Please help,
Bar.

Hello Bar,
I've tested the described approach - with extracting the StringFilterEditor template - and it worked properly on my side. I only replaced the TextBox control with a RadComboBox. I've attached my project, I hope it helps.
Also, note that there is a feature request to allow easier customization of the field filter editor, logged in the feedback portal.

Hi,
Thank you! It helped me a lot. It seems that what I needed is this:
Text="{Binding Text, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}"
This is what makes the Combobox work as the textBox.
When I began working on this I used this article: https://docs.telerik.com/devtools/wpf/controls/radgridview/styles-and-templates/styling-filterrow#modifying-the-fieldfiltercontrols-style
But unfortunately it doesn't mention what needs to be done with the text in order to retain the filtering functionality. Perhaps it should be added.
Thank you very much,
Bar.
Hello Bar,
I am glad that the project helped.
As for the article, indeed, it doesn't show how to bind the Text property. This is because, template customization is different based on the different scenarios and can contain any UI element. The article only points how to apply a style that sets properties of the control and also how to replace the template.
