Client-Side Validation?

Guest

I want to perform client side validation on click of a ASP.NET web Server
Button Control. How shall i call my javascript function to do that ?

Also i want that the data shall be posted to the server only after
validation is performed. If the validation fails i don't want the page to be
posted back to the server.

Pls help?
