Not until you actually tell us what the error message is...

You probably don't want the "/" at the beginning and end: they would be
interpreted as literal "/" characters to match against, NOT regex
delimiters.
Also you don't need the ^ and $ here: the RegexValidator checks that the
entire string matches (as opposed to only a substring).

Hi Win,

As for the regular expression error, do you mean that the ASP.NET page will
raise exception when you try running the page that contains the regular
expressioni validator? Or you means the validator control will display
validation error?

For syntax of regex in ASP.NET context, you can refer to the following
articles:

#How To: Use Regular Expressions to Constrain Input in ASP.NET

#Regular Expressions in ASP.NET

BTW, the regulator is a good regex tool built with .NET framework, I think
it will be helpful when we editing regex that will be used in .net
application:
