Answer 1

if you add another table to the xsd form after adding the report to the report viewer you might get this error.

1. delete to report viewer and add it again
2. set the report to the report viewer

3. now go to the Load event of the form (that includes the report viewer and add the Fill for new dataset.

   private void rptForm_Load(object sender, EventArgs e) {
     this.vwrpt_TableAdapter1.Fill(this.DataSet1.vwDataset);
   }
