Hello,

The exporting feature of grid work with regular postbacks only because the grid prepares additional information when performing export operation (available on postback).

You can find more information on exporting from ajaxified grid by going through the following link.

The above fix is for ASP.NET web application. If you are using SharePoint visual webpart then look into the following URL
http://www.telerik.com/community/forums/aspnet-ajax/grid/export-to-excel-in-sharepoint-application-page.aspx
It should fix the issue.

Thanks,
