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;

Hey,

as in the title the event doesnt trigger. It does work with the Widget "WidgetContentType = TwoStatesContent".

Im using a custom form for testing: https://pdfhost.io/v/xQU.fKEP6_24_anlage01_bauantrag_2021https://pdfhost.io/edit?doc=5b66dfdd-fafc-4589-bad0-c1608a8ecf1c

Thanks

Hey,

I want to create a custom command that fills the selected field with text.

I don't want to use the context menu that you can add to the PDFViewer because, as far as I know, you can't select the field you want the data to be in. If I'm wrong here, please feel free to correct me.

You can see the context menu I'm referring to in the attached screenshot (Context Menu).

I hope you understand my intentions. If not, please ask, and I can clarify.

Thanks.

The Fields in my pdf viewer are all collored white and they are not getting highlighted. As seen in example.png. I want to have the same behavior as in the example2.png.

Thanks for the help

Hi,

I attached a little wpf application that open a pdf file (to put in building folder ) with an image inside.

I tested it in 4 machine (2 w11, 2 w10): I can see the image in 2 machine (1 w11, 1 w10), and I can't in the others (1 w11, 1 w10), what could be the problem?

Thank you

• I just downloaded the most recent trial
• I installed the nuget package
• I pasted the xaml from "PdfViewer FirstLook Demo" in the SDK Sample Repo
• Everything is working fine in term of functionality at design and runtime
• *Except the theming is AWFUL looking (though in your Telerik Demo App Win11 looks really great and that's what I need)

Also, can't install the SDK Sample Browser (it says I need sharepoint, which I installed and it still says I don't can't install it.. anyways it looks like old stuff why not use a recent installer?).

Honestly, I tried a month ago Devexpress, and I found their product WAY MORE easier to use; the theming mechanism is super intuitive (ThemeManager.ThemeName="Win11Light" that's it, just out of the box). Unless I'm missing something with Telerik?

I hope you can help me so I can eventually enjoy Telerik which looks nice in the Demo (But I wasted A LOT of time trying to resolve these 2 issues (theme and installing the SDK Browser)

Thank you.

Hi

Is it posible to add a custom button to the pdfviewer toolbar in UI for WPF?

Hello,

I use RadPdfViewer to view a PDF file in my WPF application, the PDF file has only one page and the contents are in the middle of the page, so I'm trying to zoom and focus on the middle of the page, I use the following code:

private void DocumentChanged(object sender, DocumentChangedEventArgs e)
        {
            pdfViewer.ScaleFactor = 1.3;
            var size = pdfViewer.Document.Pages[0].Size;
            pdfViewer.ScrollToVerticalOffset(size.Height * 0.3);
            pdfViewer.ScrollToHorizontalOffset(size.Width * 0.20);
        }

however, I only see the horizontal scroll working.

How can I zoom then scroll to vertical and horizontal offset?

Hi Team,

We are using RadPdfViewer in .net 6 WPF application. It is failing to load 3D PDF content. We found the very old thread about this feature from around 2013 and it says this feature is not supported. Is there any option to show the 3D content in latest PDF control or any plans to release this functionality in near future ?

Thanks in Advance.
