I didn't find anything online about this so I debugged the ASP.
Page_Validators Array of elements This is an array containing all of the validators on the page.
The method to enable or disable a validator is: is the reference to the event that triggered the validation.
I wrote a post a few months ago about how to write a custom validator for a Checkbox list, but I was dealing with a completely new validation pattern.
But what if I only want to enable the validation of certain field based on certain conditions?
Unfortunately, the form validation isn't telling me what I'm doing wrong.
I got the script from and followed a tutorial for client-sided validation.
