Validators not working on other browsers except IE

I have problem in which I found out that the validator controls in which I have used in my asp web application does not work on other web browsers such as Opera and Netscape. But they work fine in IE.





I'm using :





RequiredFieldValidator


RegularExpressionValidator





In other browsers other than IE, those validations are bypassed by the system.





Can anyone give some information as how can I make use of those controls in other web browsers other than IE.





thanks
