Javascript frameworks work no matter what the serverside language is. I Recommend jquery. I write tutorials on it, see my signature for a link.
Thanks, For your replay. I am looking for specific solution. Specially available for classic asp some custom coding may me. ready to use solutions.
jQuery is a simple yet powerful framework, should be able to integrate with most server-side languages
