This was working fine in a Xamarin Forms (UWP) project

        public void PrintReferralReport(byte[] pdf)
        {
            pdfCurrent = pdf;
            this.pdfViewer.Source = pdf;
            memberReferralPopUpVM.IsPDFGridVisible = true;

        }

<telerikPdfViewer:RadPdfViewer x:Name="pdfViewer" Grid.Row="1"/>

As soon as Telerik.Documents.Core was added to a different project (doesn't even have to be used), the viewer stopped appearing.

I am working on a xamarin application, I have to display Pdf and Docx files within the application, for Pdf I am using telerik PdfViewer, but can't find a telerik control to display docx within the application. Is there any telerik control to display docx files within the application?

How would I add a close button to the toolbar.  This seems a standard button folks would want

Hi,

I have developed an Xamarin application that in Modal show a pdf in a PdfViewer.

 

When the Modal is open, I assign a url to the PdfViewer source.

 

Everything is fine when I run the android app on debug mode, but when I run in release mode the PdfViewer show this message: "an error occurred while loading the document"

I'm using RadPdfViewer control to show pdf document in our Xamarin form app. The app is working fine on Android(device and Simulator) and also on iOS simulator.
But App is crashing on iPhone device while launching the app. I'm getting the below error

 

Failed to force load assembly Telerik.XamarinForms.DataGrid.dll. Type:Telerik.XamarinForms.DataGrid.DataGridLocalizationManager.

Exception: 'You MUST call Xamarin.Forms.Init(); prior to using it.'. Callstack: '  at Xamarin.Forms.Device.get_PlatformServices () [0x00007] in D:\a\1\s\Xamarin.Forms.Core\Device.cs:87

If I comment out the <telerikPdfViewer:RadPdfViewer x:Name="pdfViewer" /> control in the .xaml file the app loads properly

I have tried the solution provided on TelerikForm.Init() but it's not worked for me.

Once we display the PDF in the viewer, how can the user to print it in a UWP app?

I'm using the pdf viewer in a xamarin solution, which includes a UWP application. A pdf can be displayed no problem on the UWP app, however as soon as a mouse scroll is done (to try and scroll down in the pdf, for example), the application crashes without any error message or other signs for what went wrong. Breakpoints and debugging mode in visual studio haven't helped identify the issue. 

Is this a known problem with the pdf viewer component? Any advice on a resolution would be much appreciated.

Hello. I'm trying to implement a control for displaying Terms and Conditions on my app using PDFViewer. I want to have an "accept" button below the viewer that Will become enabled when the user has scrolled to the bottom of the PDF (and hopefully read the document).

For this I would like to know the page number the user is currently Reading, and perhaps also an event that fires when it changes. Is this available in the PDFViewer control? I found references to VerticalScrollState, but that seems to only be available for Windows (is that right?)

What would be the correct approach to get this behavior on Xamarin Forms? Thank you
