Enabling or disabling a validator control in javascript
Recently I had to have a form that had a requiredfieldvalidator that was supposed to validate only on certain conditions. I did not want the validator to validate its control (textbox B) unless textbox A had a value in it. I decided the best way to do this was to capture the keyup event of textbox A and if there was a value in the textbox, to turn the validator for textbox B on. To do that via javascript, you have to utilize the asp.net built in javascript function ValidatorEnable.
<script type="text/javascript"> var makeEnabled = true; var validatorControl = document.getElementById('<%= RequiredFieldValidator1.ClientID %>'); ValidatorEnable(validatorControl, makeEnabled); </script>
