Hi,
I'm trying to use customvalidator to valid my textbox value. However, I have some difficulties on building a regular expression.
I use following /^[a-zA-Z0-9 -\./]+$/ but failt to valid my textbox value. I want to allow letter, digit & three characters (hyphen. dot, slash). But "\."  does not work and it validates other character and return true.
How can I validate "dot" correctly?

Go to the complete details ...
