I’m using PDFNet Windows 10 Universal App 22.214.171.124683
I have about 50 or more separated PDF pages. And to display them on screen, I combine them with PagePushBack method
Then, to update the layout, I call UpdatePageLayout on PDFViewCtrl
The first problem is after calling UpdatePageLayout, the PDFViewCtrl display blank. To fix this problem, I call PropertyChanged on PDFViewCtrl in ViewModel
Since I have 50 PDF pages on the server, and I have to download them in a queue. To reduce the wait time from downloading to reading PDF, I set PDFDoc on PDFViewCtrl as soon as the first page downloaded, then every time a page finish downloading, i add them to PDFDoc by PagePushBack and call UpdatePageLayout and PropertyChanged.
Then the second problem. The PDFViewCtrl flick every time I call UpdatePageLayout and PropertyChanged.
So how to prevent the flickering? Thanks in advanced.
