I am getting this error in the debugger when I click on one of the paging items on the grid.

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.

I have tried a lot of things and looked the demos for clues but I have no idea where the problem is. A RadScriptManager is in the main master page which NestedMasterPage2 inherits from.

Does anyone have any idea why this happening? I am using VS2010 and the project is set to .NET 3.5.

Hello David,

What you are getting is a server-side exception returned from the XMLHttpRequest. Disable all AJAX controls from your master and content page to get the stack trace of the exception. It will give you more info on what caused it.

All the best,
