RussianMove your RadWindows where their ContentTemplates are used out of a RadWindowManager. Then, you will not need the reflection workaround for the update panel anymore.
FormView eats events after ChangeMode
Question
I want to have a RadWindow dialog with FormView inside it where I could perform update or insert operations depending on FormView's mode. I created a RadWindow dialog, added controls (FormView) as a content and populated FormView's content via databinding. Everything seems fine until I try to perform Save, Insert or Cancel operations. Corresponding events are not fired.
It would seem like FormView does not call ItemCommand or any other event after I change its mode. Does anybody have some insights?
I managed to extract this functionality into trivial example where I have only Default page and RadWindow.
Here is my markup:
