Setting filter operator list from inside custom column/descriptor

[Mark]

I would like to be able to modify the list of operators in my field filter. I know I can do it in the way shown here:

 

http://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/how-to/howto-change-the-default-selected-filter-operator

 

But if I am creating my own custom GridViewDataColumn or FilterDescriptor class, is it possible to do it from inside one of those two classes, so I don't have to repeat the same event handlers for every RadGridView that I'm using them in?

Hello Mark,

In order to achieve your requirement you can use couple of approaches.

• You can create a UserControl with a single RadGridView with it and define the event handlers there. This way you can re-use the UserControl when necessary.
• Or you can create a custom control that derives from GridView and override its OnFilterOperatorsLoading() method.
