passed from portrait to landscape cause scrollview height longer and i’m not able to refresh the pdf.

You also need to call UpdatePageLayout(). If you search the sample code, or the tools code, in the PDFNet SDK, you should find usage example.

Here is the best usage.

[self.pdfViewCtrl RotateCounterClockwise]; [self.pdfViewCtrl UpdatePageLayout];

You can also see similar reply here, though since you are going through the PDFViewCtrl class, no need to do locking.
