The lack of client-side validation support outside of IE is one of many
limitations in the ASP.NET validators. That's why I built a replacement to
the whole system.
Professional Validation And More (http://www.peterblum.com/vam/home.aspx)
supports client-side validation on IE, IE/Mac, Netscape7, Mozilla, FireFox,
Opera 7, and Safari. It includes 22 validators and numerous techniques that
greatly reduce the code you write for validation.

I put together a list of the ASP.NET validator limitations I've found at
http://www.peterblum.com/vam/home.aspx so users can better plan their
project.
