Showing or Hiding Annotations in Our UWP Viewer

It’s possible to show or hide annotations in the PdfView. The methods of achieving this are similar to setting the visibility of the toolbar.

If a PdfView is being used, then the options can be set in xaml:

<ui:PdfView ShowAnnotations="false" Name="PDFView"/>

Alternatively, you can set this at runtime:

pdfView.ShowAnnotations = false;

If you aren’t using a PdfView, then it’s still possible to set it via the controller:

await controller.SetShowAnnotationsAsync(false);
