RadWindow not working on IE9

Hi John,

Adding that AJAX setting should only wrap the repeater in a div element, as this is how RadAjax renders its UpdatePanels by default. Thus, it should not result in such a behavior change.

I tried the code again with AJAX settings in the picture and I am attaching the test case I build here as a reference, so you can compare it with yours.

In the meantime, I can suggest trying an asp:UpdatePanel instead to see if it makes a difference. You can use its AsyncTriggers collection to add the external control, or its Update() server method in case its UpdateMode==Conditional.

Regards,
