How to Disable Keyboard Shortcuts in WPF PDF Viewer?

In the WPF PDF Viewer, keyboard shortcuts can be deactivated by managing the PreviewKeyDown event. To achieve this, set e.Handled = true within the event handler. This ensures that all key events are blocked from reaching the internal handlers of the PDF Viewer, thereby disabling its default keyboard shortcut functionality.

Steps to disable keyboard shortcuts in WPF PDF Viewer

Step 1:

• Hook the PreviewKeyDown event to the PdfViewer

pdfViewer.PreviewKeyDown += PdfViewerControl_PreviewKeyDown; 

Step 2:

• Within the PreviewKeyDown event, assign e.Handled = true to indicate that the event has been handled. This action halts further tunneling to additional handlers, thereby stopping the shortcut action before WPF processes it.

private void PdfViewerControl_PreviewKeyDown(object sender, KeyEventArgs e)
{
    //Marking the event as handled so that default WPF logicdoesn'tt intercept
    e.Handled = true;
}
