Using Regular Expressions To Validate a Drop Down

[jfrost10]

hey gang,

I've got an asp.net drop down list that I want to validate. Now, asp.net has validate controls that basically write javascript validation to the web page, so I figured that the basics of how it works would be relevent on this forum.

What I need to do is write a regular expression that will either
a) evaluate against teh ddl.value property, and if its 0 display the error message.
or
b) evaluate against the ddl.text peropty for No Client Selected, and if it matches display the error message.

any help would be greatly appreciated


Thanks,
Jack
