Doing this is pretty easy, if you know how or what method to use. I wanted to disable a
Validator for a province
TextBox if the country
DropDownList chosen is USA because the state
OnChange event of the country’s
provinceValidator = document.getElementById('ProvinceValidator');
Just set the second parameter as either true or false to enable and disable a
Validator. I hope this will help those who have no clue how to go about it like I did until I found out about this function.
