Report Viewer didn't call sub Report method RRS feed

  • Question

  • I use following code to generate a PDF report:

    public partial class Report{   
     public void myMethode(DataTable DT){
            ReportViewer reportViewer1 = new ReportViewer();
            reportViewer1.LocalReport.SetBasePermissionsForSandboxAppDomain(new PermissionSet(PermissionState.Unrestricted));
            reportViewer1.LocalReport.ReportPath = @"Something" + ReportName + ".rdlc";
            reportViewer1.ProcessingMode = ProcessingMode.Local;
            reportViewer1.LocalReport.DataSources.Add(new ReportDataSource("DataSet1", DT));
            reportViewer1.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(SubReportProcessing);
            Warning[] warnings;
            string[] streamIds;
            string mimeType = string.Empty;
            string encoding = string.Empty;
            string extension = string.Empty;
            reportViewer1.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
     private static void SubReportProcessing(object sender, Microsoft.Reporting.WebForms.SubreportProcessingEventArgs e)
            //do something

    It's work fine for every main report but when it want to generate subreport it didn't call SubReportProcessing method!!!

    So can some one help me to find problem??

  • Hi amir133,

    Thank you for posting here.

    Since this thread is related to Microsoft.ReportViewer.WebForms, I find it is a webform control. Therefore, I suggest that you could post in the following forum.


    The Visual C# forum discusses and asks questions about the C# programming language, IDE, libraries, samples, and tools.
