Entry validation

[Guest]

Hi,

I would like to validate a textbox control that should NOT contain some
specific characters such as "|, $,^".
how can I do it using RegularExpressionValidator, CompareValidator or maybe
CustomValidator.
I know how to use RegularExpressionValidator to validate MUST contain but I
couldn't figure out how the RegularExpression for NOT contain.

pls help

Badis,

There are few tools on regular expressions available. This will help you to
figure out thecomplex regular expressions you want.

An msdn artilces is recommending the following tool

But i found the following regular expression tool more useful
