Selective validation?

Question

I'm developing a Webform that displays a newsletter. At the bottom the newsletter, there is a comment textbox to allow the user to post a comment. I have a RequiredFieldValidator attached to the comment box to prevent empty comments from being posted.

All is working fine but I'm trying to add a "Sign Up" function so the user can register their e-mail address to receive the newsletter in their inbox.
The "Sign Up" functionality consists of:
* txtEmailAddress,
* RequiredFieldValidator for txtEmailAddress
* btnSignUp
Now when btnSignUp is clicked, the RequiredFieldValidator for txtComments will not allow the page to postback!

I know an easy solution would be to redirect the user to another page for registering and set btnSignUp property: CauseValidation to false. I guess I'm too bull headed but I want to give the user the quick access of signing up on the newsletter page! Is there any way besides a lot of javascript to accomplish this?

Thanks,
Richard

You can set the validation group so the signup fields don't trigger the validation for the comment field

You need to create the ValidationGroup for it. RequiredFieldValidator for txtEmailAddress , txtEmailAddress and btnSignUp should be under same validation group. :-D
