How to intercept any postback in a page? - ASP.NET

Question

I want to intercept any postbacks in the current page BEFORE it occurs . I want to do some custom manipulation before a postback is served. Any ideas how to do that

Answer 1

To get the postback before a page does, you can create an HttpHandler and implement the ProcessRequest function.

Check this Scott Hanselman link for a good blog post on how to do it (including sample code).
