It seems that there is a conflict between RadAjaxPanel
in this scenario. We have been contacted with similar problems before, and are still working on designing a proper solution. It is usually possible to workaround the problem by using regular <asp:UpdatePanel>
to wrap up the RadGrid in this scenario, instead of using RadAjax
Our suggestion is to try your scenario with UpdatePanel, and if you are not able to get things working as needed, please open a support ticket and send us your project. Once we have it available, we will examine it and make the necessary changes so that all 3 controls work with one-another properly.
