Export error: The source of the report definition has not been specified RRS feed

  • User-2122596307 posted


    I created a reportviewer that will show the reports according to user's choice. With this, since my vs 2005 doesn't have ReportViewer1.Reset() method I reinstantiate the reportviewer control instead. Doing this would required me to bind the control everytime it postback. Now the problem is I dont know where to code/bind during Export. I use every method that the control has but doesn't work.

    Any help?

    im not clerly understand your problem.

    what i understand is after uploaded the report the data not presented in the report if im right then avoid the Page.ispostback on page load event.

    Actually, the problem arises when I click the Export button control of the ReportViewer after selecting what format I want it to be exported. The error comes out.
