adding new pages only if needed to pdf at runtime using c#

I have some problems adding new pages. I want to add new pages only if needed and measured by the XParagraph (text) length. If the length doesnt fit on开发者_StackOverflow社区 one page, a new page must be added. Also the header and footer need to be added to every new page. It is probably easy to solve if I know how to do that, but I dont.

I am using Migradoc Dll for generating pdf at run time

Something like this? http://www.pdfsharp.net/wiki/Invoice-sample.ashx?AspxAutoDetectCookieSupport=1
