How do I remove the built-in navigation in PDFViewCtrl?

Q: i want to hide the "navpanel" or side panel in PDFViewCtrl
with .ShowNavPanel(false). But it doesn't work as expected (see
screenshot). Is there any way to hide this panel? I have tried to use
the PDFView in
my application, but I have some trouble with the (re-)drawing of the
component. Same effect if I change PDFViewCtrl to PDFView in your
PDFViewSimple- Sample.
A: In the current version of PDFNet SDK you can call
'PDFViewCtrl.ShowNavToolbar(false)'. This function should remove the
built-in navigation toolbar. To also remove the navigation panel also
call 'PDFViewCtrl.ShowNavPanel(false)'.
