About the code
This test page is lifted from MSDN Samples but it uses Paul Glavich's DOM Validators.

 

DOMValidators
November 2003
Microsoft's validation controls (well, the validation architecture in general) is pretty cool, but severely limited by it's reliance on IE's DOM implementation.

Paul Glavich wrote a set of Validator controls compatible with Netscape using the W3C DOM v1.0 rather than Microsoft's document.all. but when I downloaded his code (it comes complete with VS.NET project) there was no 'sample' to get running immediately.

The test ASPX page in this ZIP allows you to try-out the DOMValidator controls quickly and easily. Useful to confirm your web.config setup is correct, and to test on your favourite non-IE browser (Mozilla, FireFox, Safari, etc).


Client-side validation in FireFox view this test page (client side only) which uses this web.config file

Safari Warning!

Although I understood the W3C DOM support in Safari would pretty much match Firefox, Mozilla, etc., apparently the DOMValidator controls don't work in Safari for the Macintosh. If you can offer any insight into why this might be, please subject=[ConceptDevelopment.NET] DOMValidators and Safari">send an email.

All the info you (should) need

DOM Validator Controls MSDN Samples
Web.config for Validator Sample for MSDN Samples, but useful for Paul's code too.
Test page for DOM Validator controls - used to build this test page
Paul Glavich's DOM Validators - ZIP file
Client-Side Validation in Downlevel Browsers (4 Guys from Rolla) - and A Look at ASP.NET's Adaptive Rendering which contains web.config sections for Mozilla and Safari (but still refers to FireFox as FireBird)
Web.config for Firefox & Netscape 7.1 is much more up-to-date than the MSDN page above.

Validator Control Samples
The Longhorn SDK contains samples for building controls that will work in Netscape!

Paul Glavich's DOM Validators
The original (?) cross-browser validator implementation.

Validation And More
If you want to pay for cross-browser client-side validation, you might try Peter Blum's control set - very complete and compatible with Mozilla, etc.
