Ajax controls in SharePoint application page causing postbacks

[Nick]

I built an ASPX page from scratch using a combination of the RadGrid, RadAjaxManager, RadComboBox controls ultimately to be used as an application page in SharePoint.  Everything works well and the controls are using AJAX postbacks.  I deploy the page to the LAYOUTS directory in SharePoint and it still works.  However, as soon as I convert the page into a content page and point it at SharePoint's application.master file, all the controls start doing full postbacks.  The functionality (paging, sorting, filtering, etc.) still works but all the AJAX goodness is gone.  The only thing that had changed in the page itself is the pertinent content was wrapped up in <asp:Content> controls.  The ScriptManager, RadAjaxManager, etc. controls were still there.  I attempted to put the javascript "fix" on the page as well as referenced here but to no avail.  Can somebody help me out?

Thanks!

Hi, I don't know if this will help for your problem, but at least you can try. It work for me and ajax: Ajax second postback.
