Hey,

I am trying to show a pdf from a stream via the pdfViewer,

<Grid>
         <Grid.RowDefinitions>
             <RowDefinition Height="Auto"/>
             <RowDefinition />
         </Grid.RowDefinitions>
         <telerikPdfViewer:RadPdfViewerToolbar PdfViewer="{Binding Source={x:Reference pdfViewer}}">
             <telerikPdfViewer:ZoomInToolbarItem />
             <telerikPdfViewer:ZoomOutToolbarItem />
             <telerikPdfViewer:ToggleLayoutModeToolbarItem />
         </telerikPdfViewer:RadPdfViewerToolbar>
         <telerikPdfViewer:RadPdfViewer x:Name="pdfViewer"
                                Grid.Row="1"
                                        Source="{Binding DocStream, Mode=TwoWay}"
                                PageSpacing="15"
                                MinZoomLevel="0.2"
                                MaxZoomLevel="5" />
     </Grid>

 

The view renders but there is no pdf, just a grey blank screen, there is no crash however the console output gives the following;

Im thinking SkiaSharp? but at a loss as to a solution?

Failed to bind EAGLDrawable: <CAEAGLLayer: 0x2866d0640> to GL_RENDERBUFFER 1

Hello David,

We haven't received such a report so far related to RadPdfViewer. I researched around and indeed, the error seems related to the SkiaSharp SKGLView not properly rendered on iOS,  still, I cannot reproduce it on my side.

Could you confirm that you have SkiaSharp, SkiaSharp.Views and SkiaSharp.Views.Forms NuGet packages referenced in all projects? The minimum required version is 1.68, can you tell which version you're using?

Would it be possible to try to isolate the in a runnable sample and send it over?  You would need to open a support ticket and attach it there.

Thanks in advance for your cooperation on this.

Regards,
Yana
