  Hello,
  
  i am using the flexreport in an asp.net core mvc application.
  
  Everything works fine if I render and print the report in A4.

  If, on the other hand, I export it to PDF, the page size changes making the document not conform to A4 format.

  The code is very simple.

  I am attaching both the report and the generated PDF file and the code.
  
  Can someone help me?
  
  Thanks, regards,
  
  Marco

  Hi, here the code.
  
  In the report the a4 format is set, in the PDF the dimension is set to 280x396mm.
  
  Any suggest?
  
  Regards

  
              C1FlexReport report = new();
              report.Load(filePathName, reportName);
              foreach (DataSource dataSource in report.DataSources)
              {
                  dataSource.DataProvider = DataProvider.OLEDB;
                  dataSource.RecordSource = recordSource ?? string.Empty;
                  dataSource.RecordSourceType = recordSourceType ?? RecordSourceType.Auto;
              }
  
              SetupConnectionString(report, oleDbConnectionString);
  
              await report.GenerateAsync();
              await report.RenderAsync();
  
              PdfFilter filter = new()
              {
                  Stream = new MemoryStream(),
                  DocumentInfo = new DocumentInfo
                  {
                      Author = "MANDO",
                      CreationTime = DateTime.Now,
                      RevisionTime = DateTime.Now,
                      Creator = "MANDO",
                      Title = toPdfFileName
                  },
                  PageSettings = new C1PageSettings
                  {
                      Landscape = false,
                      PaperSize = PaperKind.A4
                  },
                  FileName = toPdfFileName,
                  PdfACompatible = true,
                  Preview = true
              };
              await report.RenderToFilterAsync(filter);
              return ((MemoryStream)filter.Stream).ToArray();

  Hi,
  
  i checked the example and it works bug it was made in .Net Framework 4.8 while we are developing it on .NET CORE 6.0.

  I think there is a bug in the CORE 6.0 libraries

  Thank you, Regards, Marco Casaburi

  Hi Manish, I hope you treat this report with the highest priority. Badly exporting reports to PDF represents a very high criticality for the application.

  I am waiting for news,
  
  regards.

  Hi,
  
  We have a solution for now and it should work for you. We need to provide the setting for PdfFilter and PageSettings too. This works when Landscape is set to true.
  
  Please refer to the following code snippet for reference and try at your end.

  PdfFilter filter = new()
              {
                  Stream = new MemoryStream(),
                  DocumentInfo = new DocumentInfo
                  {
                      Author = "MANDO",
                      CreationTime = DateTime.Now,
                      RevisionTime = DateTime.Now,
                      Creator = "MANDO",
                      Title = toPdfFileName
                  },
                  PageSettings = new C1PageSettings
                  {
                      Landscape = true,
                      PaperSize = PaperKind.A4
                  },
                  FileName = toPdfFileName,
                  PdfACompatible = true,
                  Preview = false
              };
              C1PageSettings pageSettings = new C1PageSettings
              {
                  Landscape = true,
                  PaperSize = PaperKind.A4
              };
  
              report.PageSettings = pageSettings;
