  • When using local mode, the host application is responsible for executing the query and supplying the data set to the report viewer.  It sounds like you have hooked things up correctly, particularly if this was working with a SQL 2005 database.  When you code executes the query, do you receieve an error message or exception?  And if not, what is the exact error message you are seeing in the report viewer?

  • Hi Ricardo,

    In Visual Studio, in the form designer, click on the ReportViewer. Then on the right side click the small triangle and bring up the smart tags. Choose "Choose Data sources", that will bring up a dialog that shows how your project datasources are mapped to your Report datasources. Make sure everything in there looks as you expect.

    Then in that same smart tag fly out, pick "Rebind data sources". It's likely one of these two will fix your problem.

    The underlying problem is that the report isn't receiving its data. It looks like when you installed the .NET driver for SQL 2008, your project got a bit out of whack.
