I am attempting to dynamically load a usercontrol that contains a grid on a pageview. The loading of the control is no problem. I have the RadTabstrip "autopostback" property set to true and I load the usercontrol in the pageload event. The grid contains a straightforward hyperlink column that launches an edit form via javascript. This is straight from your examples. The problem arises when I try and ajaxify the Tabstrip/Multipage. If I select the tabstrip to update the mulipage from the ajaxmanagerproxy the usercontrol loads fine but it breaks the edit column. I get and "Object expected" javascript error. When I remove the ajaxification of the Tabstrip/Multipage and allow a full postback the usercontrol with grid and the edit column work as expected. It launches the editform radwindow.
