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

Try this

"\A([^\|\$|\^]*)\Z"
 
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
