I simply write a SQL query to get the records from database and it will shows on crystal report..
My code is :-

adpt = new OleDbDataAdapter("SELECT TOP 10 slsmName, SUM(NetAmt) AS TotalAmount FROM salesDetails WHERE slsDate BETWEEN #" + MF.retOriginalDate(DTP1.Value.ToShortDateString()) + "# AND #" + MF.retOriginalDate(DTP2.Value.ToShortDateString()) + "# GROUP BY slsmName ",DC.conn);
            
            TopSalesmanDataSet1 TSD = new TopSalesmanDataSet1();//TopSalesmanDataSet1 is a dataSet control
            adpt.Fill(TSD);            
            if (TSD.Tables[1].Rows.Count > 0)
            {                               
                TopSalesmanReport TSR = new TopSalesmanReport();
                TSR.SetDataSource(TSD.Tables[1]);
                MessageBox.Show(TSD.Tables[1].Rows.Count.ToString());//result is 2
                TSR.Refresh();
                report_show RS = new report_show();
                RS.crystalReportViewer1.ReportSource = TSR;
                RS.crystalReportViewer1.Refresh();
                RS.Show();
            }

problem is when I run this code, the query get records from database and its shown by message box. but on crystal report it doesn't appear.. I checked crystal report connection and design...

thanks in advanced....
