Hello,
I have to attach an xml file to a pdf document, generated by Telerik report Designer.
I have a problem at importing and exporting the generated document.
Import problems:
The MediaBox has values about 100 * 333333333, as you can see in the code, i already tried to reset its size.
Other Unknown problem:
Theres is no text displayed in the exported pdf, but the imported document has a page, and has page.Content.count=80, so there was data imported.
I already tried to remove/implement the PDFA-3b Standard for generation and exporting, but it is still the same result.
The generated document was validated and has correct PDFA-3b Standard.
I also tried to set the font to black via editor, because i thought theres maybe a font problem.
This problems only occures with invoices created by ReportDesigner.
A self created word document, exported to pdf works well.
Code for generating the document by ReportDesigner:
public void Export(object param)
{
try
{
Logger.Log("Executing PrintDialogView.Export", LogLevels.Debug, null, 2);
if (param != null)
{
Microsoft.Win32.SaveFileDialog dialog = new Microsoft.Win32.SaveFileDialog();
dialog.FileName = FileName;
dialog.Filter = String.Format("(*.{0})|*.{1}", param.ToString(), param.ToString());
var SavePath = Repository<AppSetting>.GetSingle(Context, u => u.Key == AppSettingTypes.SavePath.ToString());
if (SavePath != null && SavePath.Value != string.Empty)
{
dialog.InitialDirectory = SavePath.Value.ToString();
}
if (dialog.ShowDialog() == true)
{
// DeviceInfo für PDF/A-3 konfigurieren
System.Collections.Hashtable deviceInfo = new System.Collections.Hashtable();
deviceInfo["ComplianceLevel"] = "PDF/A-3B"; // PDFA-3b-Standard
Telerik.Reporting.Processing.ReportProcessor reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", ReportSource, deviceInfo);
//Telerik.Reporting.Processing.RenderingResult result = RenderExport(param.ToString());
using (System.IO.FileStream fs = new System.IO.FileStream(dialog.FileName, System.IO.FileMode.Create))
{
fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
System.IO.FileInfo fi = new System.IO.FileInfo(dialog.FileName);
Logger.Log(String.Format("File saved to Directory = {0}, Filename = {1}", fi.Directory, fi.FullName), LogLevels.Debug, null, 2);
ReturnExport(fi.Extension, System.IO.Path.GetFileNameWithoutExtension(dialog.FileName), result.DocumentBytes);
}
if (SaveDocumentFile)
{
DocumentNumber = GetAndSetNextDocumentNumber(SelectedDocumentLayout);
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString(), "Fehler", MessageBox.MessageBoxButtons.Okay, MessageBox.MessageBoxImages.Error);
}
}

Please ignore Line
settings.FontEmbeddingType = FontEmbeddingType.None;
it was only for testing purposes
Hi Helmut,
Thank you for reaching out. Based on the description of the results you are experiencing and the provided result document, it is highly likely that you are encountering an issue on our part.
Here are the potential issues you could be encountering depending on the Document Processing version:
- 2024.3.806 - PdfProcessing: InvalidCastException is thrown on import when culture with comma (,) decimal separator set
- 2024.4.1106 - PdfProcessing: Missing Text with specific cultures (e.g. German)
Luckily, both issues have the same workaround - manually change the currently set culture to English (en-US):
Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");If you haven't already please give this a try and let me know if the unexpected results continue to reproduce.
If they do, then the issue is most likely another one and I would require the input PDF document, generated by the Report Designer, so I can use it to reproduce and investigate the behavior on my end. Any resources you can share will be much appreciated, however, keep in mind that this is a Q&A Forum and anything attached here will be publicly accessible.
I hope this helps.
Regards,
Yoan
