How to check for an event and remove it? | iText 5 PDF Development Guide

Is there a way to check to see if a page event has already been added to a PdfWriter object? If so, can you also remove that page event?

In the Java version of iText, there's a method getPageEvent() available in PdfWriter. There should be a GetPageEvent() or PageEvent in iTextSharp that you can use to find out if there is a page event present.

To remove an existing page event, you need to set the page event to null. Adding an extra page event won't replace the existing page event, but add an extra event that will be triggered along with the original event(s).
