Parital Page Validation using validation controls

Previously i had posted an article on www.codeporject.com that is specifically for asp.net 1.0 and 1.1 when validation controls are bound the to validate whole of the page.This article discuss some client side and server side tricks to partially validating a page.In Asp.net 2.0 and later Microsoft provided validation groups that provide same parial validation functionality that i have tried to achieve in ASP.net 1.0 and 1.1. You can have a look at that post partial Page Validation.
