Enable or Disable ASP.NET Validation on Client Side

Introduction

Here is the solution to enable/disable ASP.NET validation using JavaScript.

Scenario: Suppose I have a dropdown which contains a list of Asian countries and Other when user is selecting Other than only txtOtherCity is enabled else disable, at that I disable the required field validation for Other city (rfvOtherCity).

//Syntax:
ValidatorEnable(ValidatorContronName,Boolean);
//Explanation:
ValidatorContronName:This is ClientID of the Validation control.
Boolean:true(Enable) or false(Disable)
//Example:
ValidatorEnable(document.getElementById('<%=rfvOtherCity.ClientID%>'), false);
