My problem is that when I use a RegularExpressionValidator(Internet E-mail Address) on a page it works fine on my machine (localhost), but when I push it to our Web Server the Validator does not work.

I don't use any of the built-in validators if that's what you're talking about. They are way too buggy for me. Exactly as you are reporting. You can create your own validator function and use regular expressions for any type of character validation you need. If you'd like to do that instead, let me know.

Thanks,

I have never had a problem with the RegEx validators, on my Dev Machine or on my production server however, as rstelma said, you can create your own functions to preform these kinds of checks namely from the System.Text.RegularExpressions namespace.

Yeah, I was really excited at first with the .NET built-in validators. But doing the error checking in the code behind or in the object library gives me so much better control and I don't have to worry about either the fickleness of javascript in the built-in validators or in the client browser javascript handlers.

I'm sure there are people that use them without any problem at all. Just a personal choice I guess but I have seen quite a few of these same postings here,... trying to work out bugs in the built-in validators.

I dont have problems with the built in validators because I deploy my apps on an intranet, my department has complete control over all the pcs so I know exactly what client types's im going to be serving.

I have not used these in a widespread manner across the net so I do not have a basis of comparision.
