Custom Editor RadGridView and CellEditEnded or how to handle changes

[Pavel]

I created a different Edit control by "public override FrameworkElement CreateCellElement( GridViewCell cell, object dataItem )" method. The edit control is a button that display ChildWindow by the click, but after the window display the CellEditEnded event triggered  (Silverlight) but I didn't change the value and after the window closed i need to trigger the event again. How can I do it?

Or ... How Can I trigger  CellEditEnded event?
