Hi,
I followed instructions from here http://docs.telerik.com/devtools/aspnet-ajax/controls/window/how-to/how-to-use-radwindow-with-ajax to build updatepanel into a RadWindow ContentTemplate.
When I use <embed> or <object> tags in the ContentTemplate the AJAX breaks and switches to full postbacks.
Seems obvious as object and embed tags create their own DOMs...anyone aware of a solution to workaround this? Sorry for the offtopic.
