Hi,
in few words the problem is:
when i am trying to use $.event.trigger after an ajax request made with RadAjaxManager I am not able to catch the fired event in user controls.
If i put the event handler in default.aspx there is no problem and the event is "catch" but in user control the hndler is never fired...

Here my code, any suggestions? Thank you in advance...
