Hello Freinds,
 i have been getting this Complier Error Message: BC30560 'ReportDataSource' is ambiguous in the namespace 'Microsoft.Reporting.Webforms'
I googled to find the solution and found it is because of the version difference. The project was created in visual studio 2005 and currently i am working on visual studio 2008. So i went to web.config file and changed the reportviewer version from to Then sometimes it works and sometimes it shows this error!  When i uploaded my project on the testserver and try to open this file it says the "page cannot be displayed" I don't know what else to do.
please help!
