Sending parameters to Subreport in Crystal Reports and Failed to save document Error

Hi,

Using VS 2008.

I have two stored procedures, one used to get data for the main report and other for Sub report and both the SP's use the same parameter QuoteID.

I have send parameter to main report  using ReportDocument. But I am not aware how to send parameters to SubReport.

I tried many diff ways using the reportdocument's setparameter method which also takes subreport name as argument.But it didn't.

Below is the code I have used

           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);

                //objReportDocument.Subreports[Application.StartupPath + @"\BatchSubReport.rpt"].SetParameterValue("@QuoteID", ValQuoteID);

                //objReportDocument.Subreports["BatchReport.rpt"].SetParameterValue("@QuoteID", ValQuoteID);              

                string[] Print = objAPM.GetPrintDetails();

                SetPrintParameters(objReportDocument, Print);

                obj.Show();

                objReportDocument.ExportToDisk(ExportFormatType.PortableDocFormat, FilePath);

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message);

            }

Sending parameter to Subreport

//objReportDocument.Subreports[Application.StartupPath + @"\BatchSubReport.rpt"].SetParameterValue("@QuoteID", ValQuoteID);

//objReportDocument.Subreports["BatchReport.rpt"].SetParameterValue("@QuoteID", ValQuoteID);              

////objReportDocument.SetParameterValue("@QuoteID", ValQuoteID,"BatchReport.rpt);

nothing worked.I have already wasted two days on this. [SD_SalesOrderReport;1] main SP and [SD_GetBatchReportDetails;1] subreport SP.

It would be great if someone can provide a solution for this.If there are some changes to be made in designed please share images.Thank you.
