In my form I have used Page Viewer to view PDF files stored on SharePoint. It works like opening pdf file in any web browser, the same features are shown. However, we have a requirement to allow users to add their comments and save the pdf file. Having the users re upload the document everytime is not very user friendly and would make the job easy to do... Is there a way we can allow the users to update the pdf file with their comments in nintex form without re uploading??
