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.

As an effect of this, characters, which are not contained in the StandardEncoding names, e.g. umlauts, are measured with incorrect glyph widths. This leads to incorrect glyph positioning in RadPdfViewer.

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.

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.

I am Lazy Loading a document in a TabViewItem on the RadTabView Control. Here are the steps.

 

1. My Page opens and I am on my Main Tab.

2. The user has two Bottom Menu Options, one of them is for a view of a Document.

3. The user selects the Document Tab Option, and the I fire an Async operation that Loads a Byte Array that the PDFViewer is bound to. This loads fine. The document successfully loads in the viewer.

4. The user goes back to the Main Tab

5. The user then selects the Document Tab Option again, the Byte Array is already loaded so I do not Load it again in my ViewModel. So, I am not updating the Source Property on the PDFViewer again once it is loaded. I also tried just reloading the document with the same results.

The application just crashes. My guess is the Rendering or Re-Rendering of the Pdf Document between Tab Selections and there is someting 

 

If the document is never loaded, the app does not crash. However, once I load the document in the PDFViewer that exists on a Tab, the Application will crash if the user moves between tabs.

   Stack Trace from the Native Crash Reporting from the Application Output Window.

Example of my Binding. Very simple Byte Array Binding, and out of the box example from the QSF Code. I also tried using a Stream and it does the same thing.

public byte[] Document
{
    get => _document;

The command does not accept an int as a parameter. It requires the parameter to be string and not to be an index, but a page number.
