I'm having issues running RadScriptManager on a page that's uisng the RadGridView.  If I use the regular ScriptManager I get javascript errors and the GridView does not let you select rows.  If I switch to the RadGridView I get this:

Object reference not set to an instance of an object.


[NullReferenceException: Object reference not set to an instance of an object.]
   Telerik.RadMenuUtils.RadControl.GetUpdatingUpdatePanel(Control target) +101
   Telerik.RadMenuUtils.RadControl.IsInAjaxUpdatePanel(Control target) +50
   Telerik.RadMenuUtils.RadControl.Page_PreRenderComplete(Object sender, EventArgs e) +21
   System.EventHandler.Invoke(Object sender, EventArgs e) +0
   System.Web.UI.Page.OnPreRenderComplete(EventArgs e) +8698542
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1029

Hello Albert ,

Could you please elaborate a little bit more on your application? How the RadGrdi is declared? Please provide some more code so we soul further investigate on the problem.

All the best,
