            ReportDataSource rds = new ReportDataSource("ProductsDataSet", ds.Tables[0]);
            this.reportViewer1.LocalReport.DataSources.Clear();
            this.reportViewer1.LocalReport.DataSources.Add(rds);

            System.Data.SqlClient.SqlDataAdapter ad = new System.Data.SqlClient.SqlDataAdapter(sql, sqlConn);
            System.Data.DataSet ds = new System.Data.DataSet();
            ad.Fill(ds);
            sqlConn.Close();
            return ds;
        }
    }
}

In my data set i have 3 tables. I select the bind source on the top of the reportviewer where a little arrow shows.

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.
