Disable some ASP.Net validation controls when a ch

Question

I'm using old fashioned ASP.NET validation (ugh) for a checkout process. I have a checkbox -"I'll call with my credit card details"-. If checked I need to disable the required field validator and cc validator for the credit card number both on the client and on the Postback.

How do it do it?

Answer 1

You can disable the validators server-side:

MyFieldValidator.Enabled = MyCheckBox.Checked

Page.Validate()
If Page.IsValid Then
   'stuff
end if

Answer 2

You can disable the validators client-side (in javascript):

function disable(validatorId)
{
   var validator = document.getElementById(validatorId);
   ValidatorEnable(validator, false);
}

Where validatorId is the clientID of the validator to be disabled. See this page for a complete example.

Answer 3

If you're disabling server side then you can do

button1.CausesValidation = False

in your CheckChangedEvent this is more helpful if you have a lot of validators and need to disable them all.
