Avoid validation on click of specific button

Question

This question is regarding validation. I have regex validation on some fields as show in the snapshot. I want to run this validation only when user clicks on Add button; NOT when the submit button is clicked. Could someone suggest how this be done?

Answer 1

Set the CausesValidation="false" for the submit button.

You could also place the RegExValidator and the Add button into a separate ValidationGroup.

Answer 2

use the CausesValidation Property. Set to False
