How do I validate RequiredFieldValidator/CompareValidator conditionally. I have aded equiredFieldValidator/CompareValidator on date textbox. I want that if textbox1="No" thne it should not validate or compare date text box, if textbox1="Yes" then it should validate.

I have a text box, a range validator, and a button. The validator is hooked up and prevents the button from doing a post back if the text is out of the range, however I'd also like to enable and disable the button. Is this possible to do within client-side code?
