  Hi,

  Using: ActiveReports v16, Visual Studio .NET v4.8.1 WinForms application

  I’m trying this code to merge a 2nd report into the 1st report but its not working:

  ddRpt = new rptA();
  
  ddRptB = new rptB();
  ddRptB.Run(false);
  
  ddRpt.Document.Pages.AddRange(ddRptB.Document.Pages);
  
  frmPreview pvPreview = new frmPreview();
  pvPreview.ARViewer1.LoadDocument(ddRpt);
  Application.Run(pvPreview);

  When it opens the preview, it displays only the page from the first report. Any idea what could be wrong and how to resolve this? Thanks in advance!

  Hi Steve,

  You’ll also need to ‘Run()’ your main report (‘ddRpt’) and load the ddRpt.Document in the viewer.

  Running your ddRpt will render the first report into the report.Document and merging the pages from the second report will append the pages to your ddRpt.Document which you can load in the viewer.

  Refer to the code snippet below:

  ddRpt = new rptA();
  ddRpt.Run();
  
  ddRptB = new rptB();
  ddRptB.Run(false);
  
  ddRpt.Document.Pages.AddRange(ddRptB.Document.Pages);
  
  frmPreview pvPreview = new frmPreview();
  pvPreview.ARViewer1.LoadDocument(ddRpt.Document);
  Application.Run(pvPreview);
  

  Please find attached a sample implementing the same.

  Regards,
