How to get a (text) selection on a specific page

Technical Support Apryse SDK
1

in the java version, something like this is possible:

PDFViewCtrl.Selection selection = m_pdfViewer.GetSelection(m_pdfViewer.GetCurrentPage);

Is there any way to do the same using winforms?

Yes, the same API exists for WinForms.

Perhaps you need to update to a newer version of PDFNet.
