Hi,

I have an application which makes extensive use of the CRUD capabilities of the ASP.NET Ajax:Grid. It is generally wrapped inside a RADAJAX Panel (Code included below). Everything worked fine until we made two changes to the application.

1. We upgraded the Telerik Controls from 2008.3.1125 to 2008.3.13142. We removed the RadMenu from the Masterpage and replaced it with a RadPanelBar.

Since making these changes everything works fine except that once the Grid enters Edit mode either for an Insert or Edit to be performed it becomes unresponsive. Clicking on the Update, Cancel, Refresh and Insert Links has no effect. We then removed the Grid From the RADAJAX Panel and it worked fine. I tested the Grid when targeted by the Telerik AJAX Manager and the same problem occurred.

I replicated the problem on a machine running Windows 7 Beta in both Firefox and IE. I then replicated the problem on Windows Vista and Windows 2003 machines running IE7 and Firefox.

Any suggestions?

Thanks.

Hello Johan Pienaar,

I tried to reproduce this problem but to no success.

Please, review the attached sample for comparison with your implementation. In addition, could you try to reproduce the issue with a MS UpdatePanel control and let us know of the result.

Thank you.
