if (oDataSet.Tables.Count > 0)
{
   oDataSet.Tables.Add(oDataTable);
   ReportDataSource rd = new ReportDataSource("Letter", oDataSet.Tables[0]);
   ReportDataSource rd1 = new ReportDataSource("DataSet1", oDataSet.Tables[1]);
   this.TemprptViewer.LocalReport.DataSources.Clear();
   this.TemprptViewer.LocalReport.DataSources.Add(rd);
   this.TemprptViewer.LocalReport.DataSources.Add(rd1);
   ReportParameter p2 = new ReportParameter("CurrentDate", DateTime.Today.ToString("MMMM dd, yyyy"));
   this.TemprptViewer.LocalReport.SetParameters(new ReportParameter[] { p2 });

   page.Session["GridBind"] = "a";
   this.TemprptViewer.LocalReport.Refresh();
}
