Hi guys need help..this is my c# code to print data using crystal report.i have added two subreports named TempItems and TempReciptSummary. before adding TempReciptSummary it works fine..TempReciptSummary does not take any dataset it just has some string type parameters...

DBAccess_TrxView dbt = new DBAccess_TrxView();
            DBAccessStockAdjReport dba_r = new DBAccessStockAdjReport();

            ReportDocument rptDoc = new ReportDocument();

            TempReceptDataSet ds = new TempReceptDataSet();
            DataTable dt = new DataTable();
            dt.TableName = "Crystal Report Example";
            dt = dbt.CrystalReportGRMITEMS(ADVNo);

            ChqTempDataSet ds_ = new ChqTempDataSet();
            DataTable dt_ = new DataTable();
            dt_ = dba_r.CrystalReportChqDetails(ADVNo,"H");


            ds.Tables["TempItem"].Merge(dt);
            ds_.Tables["TempCheque"].Merge(dt_);

            string path = Path.Combine(Environment.CurrentDirectory, @".\TempReceipt.rpt");
            // Your .rpt file path will be below
            rptDoc.Load(path);

            //set dataset to the report viewer.
            rptDoc.SetDataSource(ds_);
            //rptDoc.DataSourceConnections.Clear();

            rptDoc.Subreports["TempItems"].SetDataSource(ds);
            rptDoc.SetParameterValue("VenName", txtCusName.Text);
            rptDoc.SetParameterValue("VenID", txtCusId.Text);
            rptDoc.SetParameterValue("Addr1", txtCusAdd1.Text);
            rptDoc.SetParameterValue("Addr2", txtCusAdd2.Text);
            rptDoc.SetParameterValue("Addr3", txtCusAdd3.Text);
            rptDoc.SetParameterValue("GRMNo", ADVNo);
            rptDoc.SetParameterValue("DATAMATION", txtUserId.Text);


           //Parameters for Summary subreport
            float cash = 0f;
            float cheques = 0f;
           float creditcard = 0f;

           if(txtCash.Text.Length != 0)
           {
               cash = float.Parse(txtCash.Text);
           }
            if(txtCheque.Text.Length != 0)
           {
               cheques = float.Parse(txtCheque.Text);
           }
            if(txtCrdtCrd.Text.Length != 0)
           {
               creditcard = float.Parse(txtCrdtCrd.Text);
           }

            rptDoc.SetParameterValue("CASH", cash.ToString("N"), "TempReciptSummary");
            rptDoc.SetParameterValue("CHEQUES", cheques.ToString("N"), "TempReciptSummary");
            rptDoc.SetParameterValue("CREDITCARD", creditcard.ToString("N"), "TempReciptSummary");
            rptDoc.SetParameterValue("AdPaid", lblTotPaid.Text, "TempReciptSummary");
            rptDoc.SetParameterValue("BalDue", lblDueBalance.Text, "TempReciptSummary");
            rptDoc.SetParameterValue("GoodsTotal", lblTotAmount.Text, "TempReciptSummary");
            rptDoc.SetParameterValue("Total", lblTotPaid.Text, "TempReciptSummary");



            System.Drawing.Printing.PrintDocument printDocument = new System.Drawing.Printing.PrintDocument();
            rptDoc.PrintOptions.PrinterName = printDocument.PrinterSettings.PrinterName;
            rptDoc.PrintToPrinter(1, true, 0, 0);


            crystalReportViewer1.ReportSource = rptDoc;

My problem is it does not print data and no exception is given..i dubug the code and found that the last line of the code

crystalReportViewer1.ReportSource = rptDoc;

does not execute..after the execution of line

rptDoc.PrintToPrinter(1, true, 0, 0);

it exits..Need your help...Thanks
