How do I write a custom validator for the onkeyup event.
my scenario is two textboxes and if one of them is filled the other has to be filled to. if not both need not be filled(so, onkeyup event should trigger the requiredfield validation for the other text box and vice versa). I am able to write validation for one text box but unable to write validation for my case.
