  • Hi.....Binay TIwari

    Your problem is because of the dll reference.

    I think you have not added 'Microsoft.ReportViewer.ProcessingObjectModel.dll in your application. If you have add this in your application then just.

    rigth click on it and select properties. Now Change Copy to Output Directory property to Always Copy and rebuild your project again.

    One more thing is that just check your rdlc file and make sure that it has no any error.

    Best of luck

  • Check as Hiren said, and also as an initial check - see if Microsoft.ReportViewer.ProcessingObjectModel.dll  is in your global assembly cache - if not you need to download and install the Microsoft Report Viewer.
