Hi Stephen,

ASP.NET Validation controls work in client side(using javascript) and on
server side too(like Page.IsValid).

The validation controls do not work with Netscape (client ..javascript) but
if you have written (you must write if you have'nt) any

server side validation code that works irrespective of browser.

So if you need to validate ( client) for netscape too..you have to write you
own javascript for validation .

[For your knowledge: The javascript that is emitted by ASP.NET validation
controls make use of WebUIValidation.js file which works only with IE
but not with other browsers.]

Best practise: do validation both on client side as well as server side.

Hope this helps you.

Thanks
