RequiredFieldValidators for my ASP.NET pages work fine for IE 6.0 but they do not work at all for Netscape 7.1. Is this normal or are they supposed to be working for both the browsers? Thanks.

I have found for Netscape 7.1 that they post back before they are validated.

You could do this : if ((Page_ClientValidate()) on clicking a button.
This could force it to do the evaluation of required validators.
You could use a dummy text box with a required validator with no error
message. In your button click handler, you would write:

dummytext.value = "1".
if ((Page_ClientValidate()) {

  dummytext.value = "";
}
See what happens..
