I want to change the language option in PDF, i.e., Document Properties > Description > Reading Options > Language into English. Is that possible to do?
Document Properties (Initial View Settings). Page Layout should be set to ‘Single Page Continuous’ and Magnification should be set to ‘Fit Width’.
For best customization, you should use our PDFViewWPF class, and the associated tools project. For our older PDFViewCtrl class, there is no means of localizing the text of UI elements.
