  using (PdfExport pdf = new PdfExport())

  					pdf.ImageQuality = ImageQuality.Highest;
  					pdf.Export(m_reportBase.Document, output);
  					result = true;
  				}
  
  

  We are using
  
  GrapeCity.ActiveReports.Web.v10

  Any workaround or fix for this?

  Hello, it appears that I am experiencing a similar issue with my application, using my newly-upgraded ActiveReports Standard v13.

  In my case I am exporting a SectionReport to a PDF using the following code:

   PdfExport pdfe = new PdfExport();
  
              try
              {
                  ar.Document.Printer.PrinterName = "";
                  ar.DataSource = DataSource;
                  ar.DataMember = DataMember;
  
                  ar.Run();
  
                  pdfe.Export(ar.Document, memstream);
  
              }
              catch (Exception e)
              {
                  throw e;
              }
  

  This does work on most of my multiple reports without any issue, but there are a few for which I receive an exception (below) I was hoping to find out what the issue was in this thread and/or if there are any suggestions as to what to look for? Thanks in advance.

  (also note that all of these reports have previously worked with Activereports 7 – the conversion to AR 13 mostly involved changing what was ActiveReport to be a SectionReport) Thanks!

  Hello,

  It is possible that your report contains charts that might cause some issue.
  
  The reason of this exception was unclear by looking at the stack trace.
  
  Could you please share that report which you are trying to export? In case you wish to share it privately, you can create a case on SupportOne (https://supportone.componentone.com) and share the same.

  Best Regards,
  
  Esha

  Thanks for your response… I believe I have the issue resolved (or at least identified) My resolution (for reference) was as follows:

  While my report did NOT contain a chart, it DID contain images – I deleted the images completely and the report was able to export fine.

  I have since tried to identify exactly what is wrong with the images – it seems that in the reports that DO work, the images are contained as resources within the .resx file of the report itself. I reviewed the originals, and it appears as if the conversion process somehow resulted in the .resx file entries for the images being removed for the failing reports. The generated code still held entries for the images, BUT the images were always null when the InitializeComponent() function was called.

  Luckily, the images are the same across the working and non-working reports, so I was able to use the images from the working reports to rebuild the failing ones.

  Thanks for your assistance.

  Kind regards,
  
  Blair

  Hello Blair,

  Thanks for informing that the issue is resolved for you.
  
  I tried the scenario at my end using the latest builds but the issue could not be observed.
  
  There was an issue in the earlier versions of AR 13 wherein there was an issue loading images in a report. However, it was fixed with the hotfix builds: http://cdn.grapecity.com/ActiveReports/AR13/hotfixes/ActiveReports-v13.0.16604.0%20(1).msi .
  
  You can try your application with these builds.
  
  If the issue persists, share the stripped down sample so that I can investigate on the same and assist you further.

  Regards.
