ASP.NET - how to stop unrequired server validation <p>I have used ValidatorEnable to disable a RequiredFieldValidator in javascript. However on postback the control being validated by the validator is still validated ... even though I disabled the validator on the client.</p> <p>I understand why this is happening since I've only disabled the client validation ... however is there a nice way to determine that I've disabled the client validation and to then disable the server validation on postback?</p>
