I have a user control hosted inside the SitefinityWebApp (university) sample site that comes with the 4.0 Beta.
when sending an ajax request (for example for filter) an exception occurs:
Microsoft JScript runtime error: Object doesn't support this property or method
the line is:
When the RadAjaxManager is not included it is working fine. The code also works fine (with RadAjaxManager) in a stand alone application.
Thanks in advance for your advice.
