  ActiveReports 17

  Hi! How can I export a RDL Multi-Section report to memory stream? We have some older, winform reports in ActiveReports 14 that uses this code:

   Dim memStream As New System.IO.MemoryStream
   Dim pdfExport As New GrapeCity.ActiveReports.Export.Pdf.Section.PdfExport
   Dim docAllInvoices As New GrapeCity.ActiveReports.Document.SectionDocument
  
   pdfExport.Export(docAllInvoices, memStream)

  I’m using this in a C# web service and have this code:

   PageReport pageReport = new PageReport();
   System.IO.FileInfo fi = new System.IO.FileInfo("C:\\My Dev\\Reports\\MyReport.rdlx");
  
  //tried this but this fails because it's not a section report
   GrapeCity.ActiveReports.Export.Pdf.Section.PdfExport pdfExport = new GrapeCity.ActiveReports.Export.Pdf.Section.PdfExport();
   System.IO.MemoryStream memStream = new MemoryStream();
   
  pdfExport.Export(pageReport, memStream);
  
  //so tried this but this fails because of the screenshot included
   GrapeCity.ActiveReports.Export.Pdf.Page.PdfExport pdfExport = new GrapeCity.ActiveReports.Export.Pdf.Page.PdfExport();
  System.IO.MemoryStream memStream = new MemoryStream();
  pdfExport.Export(pageReport.Report, memStream);

  I tried to locate this information in the documentation but I only come up with how to do this with Section reports, like here:

  Thanks!

  Hi Melissa,

  We were able to replicate the same on our end when exporting a PageReport to PDF using PDF ExportFilter, we have escalated the same to our development team for their insights on this [Ticket ID: AR-30823].

  For now, to export your PageReport to a MemoryStream you can use the PdfRenderingExtension and export your report to MemoryStream using the following code:

  MemoryStreamProvider memoryStreamProvider = new MemoryStreamProvider();
  pageReport.Document.Render(pdfRenderingExtension, memoryStreamProvider, pdfSetting);           
  MemoryStream ms= memoryStreamProvider.GetPrimaryStream().OpenStream() as MemoryStream;
  

  Please find attached a sample for the same.

  Regards,
  
  Anand
