I've tried to integrate RadGrid into an application page of SP2010. After following the article http://www.telerik.com/help/aspnet-ajax/moss-deploying-radcontrols.html
, I got error when loading the default site page (without RadGrid). If I remove the two <safecontrol> entries from web.config, the home page (without RadControl) can be displayed. But the page with RadGrid cannot be shown. It shows "An unexpected error has occurred"
. So far I don't find out what the unexpected error is.
In the application page, the RadGrid is a very simple one by binding to a static datatable using needdatasource method without any button. The version is 2011 Q1.
