PDFViewer use ContextMenu with DocumentSource Binding

[Benedikt]

Hi,

I have this code, thats not working like this.

Because of the DataContext, the DocumentSource wont work, because it needs obviously a different DataContext.
But I need this DataContext for the ContextMenu to work.

Is there a way I can have both? A working context menu and also bind the DocumentSource?

Greetings

Hello Benedikt,

To achieve this requirement, you could use the RelativeSource property of the Binding instance for the DocumentSource property to bind to the SelDatei.FilePath property. This way, the document will be correctly shown and the RadContextMenu will correctly work with the command descriptors.

The following code snippet showcases this suggestion's implementation:

<telerik:RadPdfViewer x:Name="pdfViewerZeichnungen"
                      Grid.Row="1" 
                      DocumentSource="{Binding RelativeSource={RelativeSource AncestorType=Window}, Path=DataContext.SelDatei.FilePath, Converter={StaticResource PdfDocumentSourceValueConverter}}"
                      DataContext="{Binding Path=CommandDescriptors, ElementName=pdfViewerZeichnungen}" 
                      telerik:RadPdfViewerAttachedComponents.RegisterFindDialog="True" 
                      telerik:RadPdfViewerAttachedComponents.RegisterContextMenu="True"
                      Mode="TextSelection">
</telerik:RadPdfViewer>

With this being said, could you give this suggestion a try?
