Hi,

I am using two stored procedures, one for main report and another for subreport.Below is the code.

private void LoadSalesOrderReport()
            {
               
                string Type = gvQuotationDetails.Rows[QuoteIndex].Cells["Type"].EditedFormattedValue.ToString();
                FilePath = ConfigurationManager.AppSettings["EMP_IMG_PATH"].ToString() + "\\"" + ValQuoteID.ToString() + ".pdf";
                DeleteExistingFile(FilePath);
                try
                {
                    AccountsPayableMaster objAPM = new AccountsPayableMaster();
                    QuotationReport obj = new QuotationReport();
                    objReportDocument.Load(Application.StartupPath + @"\rptQuotationReport.rpt");
                    obj.crysQuotationReport.LogOnInfo = objAPM.ConnectionDetails("SD_SalesOrderReport;1");
                    obj.crysQuotationReport.LogOnInfo = objAPM.ConnectionDetails("SD_GetBatchReportDetails;1");
                    obj.crysQuotationReport.ReportSource = objReportDocument;
                    objReportDocument.SetParameterValue("@QuoteID", ValQuoteID);
                    objReportDocument.SetParameterValue("Type","-"+ Type.ToUpper()+"-");
                    objReportDocument.SetParameterValue("@QuoteID", ValQuoteID,objReportDocument.Subreports[0].Name.ToString());                
                    string[] Print = objAPM.GetPrintDetails();
                    SetPrintParameters(objReportDocument, Print);
                    obj.Show();
                    objReportDocument.ExportToDisk(ExportFormatType.PortableDocFormat, FilePath);
    
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message);
    
                }
               
                OpenPdfFile();
            }


 


private void OpenPdfFile()
        {
            try
            {

                Process.Start(FilePath);
            }
            catch (Exception ex)
            {

                MessageBox.Show("Please install MicrosoftOffice/Pdf Reader to view files", "", MessageBoxButtons.OK, MessageBoxIcon.Information);

            }
           

    }

The code is working fine.But the problem is. when i click the button in front end to show the pdf directly.The crystal report form is also displayed and I know the reason as I am using **obj.Show** in my code.I tried to comment it but it throws an error.Can any one advise changes in my code to directly display the pdf and not the crystalreport form.
