Answer 1

I bumped into this problem while using version 10 of the ReportViewer while using Visual Studio.Net 2012 to edit code.

I found a solution by taking the name of the Data Source in the error message (in the case above, it's "Product_Detail"). I then went into source code view, found the ReportViewer, its DataSources, and then inside its ReportDataSource.

I set the Name property of the ReportDataSource to the same as the Data Source mentioned in the error message (ie "Product_Detail").

I hope this works for you as it did for me.

Also, if you have the latitude to use a later version of the ReportViewer control, you may find that this problem either doesn't appear or is easier to solve.
