I have a link that do a postback, but since i have a validator on the form control, when it try to do the postback, it check for validation and block the post back.<BR><BR>Is there a way to prevent the validator from being use on some control ?The Button class contains a property CausesValidation. If you set this to false, when the button is clicked (causing the form to be submitted), the validator(s) won't be examined. Is this what you're after?Exactly, thanks a lot
