A great first effort! Many thanks!
After some use I do have these suggestions:

1. When User changes LayoutMode the ZoomLevel property changed event should also be fired. I have a Numeric Textbox to adjust viewer ZoomLevel and would like to see its text update on a LayoutMode change. However when LayoutModeChanged fires the ZoomLevel has not yet changed nor does ZoomLevelChanged later fire.
2. The toolbar item for Fit to Width should be a Toggle in all cases, i.e. toggling between Fit Width and Fit Height (or Fit Page) and should be effective at all times (sometimes has no effect if LayoutMode changed to Single Page).
3. The toolbar item to toggle LayoutMode should honor an assignment of its text property.
4. I'm currently using the change in VisiblePagesCount to determine the document is visible. However a "Loaded" event might be even better.
5. I would like to release the viewer's memory of the document before closing the XAML page. An Unload command would be helpful. For now I just assign Source = null.

By specification the explicit destinations define a required page property. However, some documents contain definition for destinations with null page value, which causes an ArgumentNullException on import.

Provide a way through UI and programmatically to load password-protected pdf documents in PdfViewer.

Error message is: "One or more errors occurred. 
(Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfName' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt'.)"

The current implementation relies on valid cross-reference offsets in the PDF documents so that PDF objects are easily found and parsed. However, we may implement a mechanism for importing documents with invalid offsets for the objects inside the table.

Dear,
Please add bookmarks to the pdf reader.

Best regards.

By specification, names are an atomic symbol uniquely defined by a sequence of characters. However, when importing a document with names defined as an empty sequence a handled InvalidCastException is thrown which leads to missing page content.

Allow programmatic navigation of the viewport of the PdfViewer.

When User changes LayoutMode the ZoomLevel property changed event should also be fired. I have a Numeric Textbox to adjust viewer ZoomLevel and would like to see its text update on a LayoutMode change. However when LayoutModeChanged fires the ZoomLevel has not yet changed nor does ZoomLevelChanged later fire.

where if in this mode, the zoom level will be changed upon the user changing the current page (via scrolling or navigating). 

When PdfViewer is located inside Popup control, it does not take its size properly.

implement annotations handling when RadFixedDocument is imported with PdfProcessing

Paths in the documents are not visualized in the PdfViewer. 

The glyphs are rendered with additional unexpected lines when a specific custom Type 1 font is used to show them.

Provide support for lots of image formats when exporting PDF documents.

A remote go-to action is similar to an ordinary go-to action but jumps to a destination in another PDF file instead of the current file.

Even small documents containing images encoded with CCITTFaxDecode filter can take about 10 seconds to be opened.

If you download the pdf document from the internet, save it to the device and try to show it inside PdfViewer, it will not be loaded on Xiaomi phones with MIUI 12.1. and above.

Users report similar issues with downloaded files on MIUI devices, here are a few discussions on the matter:

It seems that's the same reason for the PdfViewer not showing downloaded pdf files as it properly shows pdf documents added as embedded resource to the solution.

Support for horizontal scrolling the Pdf document in the viewer: 
Horizontal single page (go through the pages swiping/scrolling left and right)
