When I Export Crystal Report To Any Other Format , It Exports It Dummy Data Instead Of Original Data That Report Is Displaying

ReportDocument rptDoc = new ReportDocument();
DataSet6 ds = new DataSet6();
DataTable slip = new DataTable();

slip.TableName = "DataTable1";


slip = BOL.product.OnlineAccountantSlip(cid); 

ds.Tables[0].Merge(slip);

rptDoc.Load(Server.MapPath("CrystalReport7.rpt"));

rptDoc.SetDataSource(ds);
CrystalReportViewer1.ReportSource = rptDoc
