I have a PDF file that's been imported into a MemoryStream object and now I need to display it using the Telerik UI for WPF pdfViewer control.  The existing documentation says that you can create a PdfDocumentSource object and bind the pdfViewer.DocumentSource to that.  However, either PdfDocumentSource no longer exists, or I can't figure out what the correct Namespace is.

   I'm using TelerikUI for WPF v2024 Q2.  However changelogs for 2020 (https://docs.telerik.com/devtools/wpf/controls/radpdfviewer/changes-and-backward-compatibility/backward-compatibility)  say that: 

Changed
Obsolete constructors of Telerik.Windows.Documents.Fixed.PdfDocumentSource:

PdfDocumentSource(Uri uri, FormatProviderSettings settings)
PdfDocumentSource(Stream stream, FormatProviderSettings settings)
What to do now
Use the overloads that accept Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Import.PdfImportSettings instead.

   I've also read that there is some kind of merge going on trying to replace the previous PDF code with Telerik.Windows.Documents.Fixed .  In any case, I can't seem to figure out how to go from a MemoryStream to something that the pdfViewer.DocumentSource likes.  

   Can anyone help with a very basic code sample to take a PDF as a memorystream and create something that pdfView.DocumentSource will accept?  Thank you!

Hey,

as in the titel is there a event or workaround to know if a userer startet to type inside a pdf text field. I just need it to set a bool true to inform the user that there is a possibility to lose data.

Thanks

As in the title it doesnt work so the movement on the document isnt great.

Thanks for the help

As in the title some charactes are getting not displayed in some pdfs.

If I import this pdf: https://jmp.sh/s/mdWM2qNDL2Oi6Yd825s0

Im getting this result its right if you click inside the field but its not getting displayed correct when not inside the field

Maybe its something with the font, thats the only thing i could think of.

Thanks for the help

          <telerik:Percent Value="150"/>
          <telerik:Percent Value="125"/>
          <telerik:Percent Value="110"/>
          <telerik:Percent Value="100"/>
          <telerik:Percent Value="90"/>
          <telerik:Percent Value="75"/>
          <telerik:Percent Value="50"/>
          <telerik:Percent Value="30"/>
      </telerik:PercentComboBox.PercentValues>
  </telerik:PercentComboBox>

Hope there is a way. Thanks

Hey,

I have set my TextField to ReadOnly but the RadPdfViewer doesnt react to it. Im getting a pdf File that im importing using the telerik PdfFormatProvider after that im trying to set some of the fields to readOnly like this: 

if (formField is TextBoxField textBox)
{
	if (field is not null)
	{
	
		textBox.Value = field.ViewValue(viewMode);
		if (field.VarType != 0)
			formField.IsReadOnly = true;
			
	}
}

Im sure its setting it because if i export it to a pdf the fields are set to ReadOnly but not in the Telerik PdfViewer

Thanks

Dominik

We updated our WPF Telerik controls from 2021.3.1109 to 2023.3.1114 and now our RadPDFViewer is not displaying text on some PDF documents. Please see before and after images. 

Before:

After:

The file is a form fill PDF document that has been flattened. This displays correctly in Acrobat, Acrobat Reader, Chrome and Edge. 

We also opened the file the 2023.3.1114 PDFViewer demo with the same results.

Hello all,

I'm using Telerik in WPF application and there are some pdf files that are not shown, the specificity of the files is that they are scanned .

Please can any one has this pb before?

Thank

So I've got an application that has been working for the last 2 years with no issue. All of a sudden on some machines the radPdfViewer will not load or display PDFs. I've updated the code to the most recent version of the Telerik WPF UI controls but nothing different. The application works fine on my dev machine and a handful of others, but there are 3 machines specifically that it fails to load on. No errors just does not load. Has anyone else encountered this issue?

Uri documentSourceUri = new Uri("https://www.somedomain.com/printables/paview.php?get_permitNumber=" + permitNumber);
PdfDocumentSource documentSource = new PdfDocumentSource(documentSourceUri);
pdfViewer.DocumentSource = documentSource;
