Hello,

I am experiencing a strange issue when I want to jump to a specific page using the PdfViewer.

OnDocumentChanged event, I set the CurrentPageNumber or call GoToPage(), but the result will be the end of the (page-1), a tiny line of that page and the page that I am requesting.

Example.

I want to jump to page 5. On first jump it shows ok, on second jump it shows a tiny line from page 4 and the page 5, but on the page counter (CurrentPageNumber) it has 4.

This only occurs on second call onward.

 

Is this a PdfViewer bug or is there another way I can go to a specific page?

Hello Tamas,

I have tried to reproduce the described issue but without any success. I have prepared a simplified demo project that allows you to change the document, call GoToPage method in DocumentChanged event handler and display the current page number. Could you please check if you reproduce the issue with this demo? I have tested it with the latest official version of the product.

In the mean time I have found the problem.

The problem comes from ScaleMode functionality. If I set it to ScaleMode.FitToWidth the GoToPage will not work right.

I found a workaround with ScaleFactor which can be calculated and then the GoToPage goes to the right page also.
