I have a .NET web application with many pages the content of which need to consolodated to single PDF file for printing and sharing with other. The simplest way to this is to use Adobe Acrobat 9 Pro IE add-ins selection "Convert to Adobe PDF" from the first page to create a PDF file, then add the subsequent pages with the "Append to Existing PDF" selection. This works beautifully, allowing the user to even higlight areas and add notes if needed. However, it only works to allow each page to be appended one time only. Several of the pages have lists or other selections at the top of the page that rewrites everything below for the selected data. Once a page has been altered, the new content also needs to be appended to the PDF file. Apparently, each page has some sort of identifier that Acrobat uses which even allows setting buttons/tabs from the first page to hyperlink to the where the page is added and/or to jump back to that page on the original web-page. Is there a way to modify this identifier so that multiple versions of the same page can be appended to the PDF? If not, is there any other way that the pages can easily be added by the user?
