MVC how to disable the required validation for some controls

I am creating a web application using MVC 4.

I have a few properties in my view model that has been decorated with the required attribute as shown,

[Required(ErrorMessageResourceName = "StateRequiredMessage", ErrorMessageResourceType = typeof(Resources.Agency.CreateEdit))]
public int? PostalAddressStateId { get; set; }

but then in my view, depending on what the user selects from a tick box, I disable some of the properties that have been tagged as required.

I disable the controls using jQuery:

$("#PostalAddressStateId").attr("disabled", true);

Then when I try to save, it says the value is required. How do I solve this?

Try

ModelState.Remove("PostalAddressStateId");

at your controller

Try this:

    PostalAddressStateId.Attributes.Remove("Required");

You might need to set a boolean in javascript and send it back to the controller, the required attribute impacts your server side code as well.

In my opinion, a field like this shouldn't be marked as required unless it's always required. If this is in a viewmodel, then I'd probably remove the attribute and replace it with a custom attribute or some other way of determining that it's filled in when it must be and not filled in when it's not required.

I would check out MVC Foolproof Validation on CodePlex. You could use the RequiredIfTrue attribute that comes with Foolproof to solve the issue above.
