Q: We have a little problem about how to update a view after we fill-
in some form elements. If we fill the form elements and we update our
PDF view, there is a small flick. We know that this occur from a view-
updating process. But our customer doesn't like it. Can you give us a
method for removing a flicking effect?

A: I suspect that the flicker is caused due to a page refresh (because
the entire page is drawn progressively from scratch).
To eliminate the flicker try setting progressive rendering to
'false' (you can uncomment the corresponding line in C#/VB.Net PDFView
sample project):
_pdfview.SetProgressiveRendering(false);
You can also set progrssive rendering 'on' and 'off' as needed.
