Disable validation controls based on a condition

Question

I have an asp.net application that uses validation controls on textboxes. However, if the user enters a value in txtFieldA, then I want to disable the validation controls on txtFieldB and txtFieldC.

Simply use this JavaScript function

function Disable()
{
  var myVal = document.getElementById('myValidatorClientID');
  ValidatorEnable(myVal, false);  
}
