Custom ASP.NET Validators give developers easy way to create validator which is tailored exactly to their needs. Last week I have encountered a scenario in which custom validator was a great solution. I was working on yet another registration form and my job was to validate if username and email address are unique with javascript. I have used Custom Validators for that because I was already using ASP.NET validators so I wanted to stick to one approach for all fields of the registration form. Within client side function I have used jQuery to call web service which will do the validation for me. The trick was to bring it all together and make sure that this solution works with asynchronous calls..
