ASP.NET MVC 4 avoid generation of data-val-date for datetime

Question

how can I avoid the generation of the html attribute \"data-val-date\" for the element created from a Datetime property?

The model:

public class Regi         


        

Answer 1

Add this to your application start in your global.asax file and the form should fire.

DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;

Answer 2

data-val-date is used by the validation system to validate the date. If you remove it, client-side validation won't work.

If that's what you want, then just disable client-side validation.

Answer 3

Ok, this took me an afternoon of work... apparently mvc4 decided that it was time to render a data-val-date="Message" on EVERY datetime property on the viewmodel. I've tried to modify this default behaviour but didn't succeed.

This solved my problems:

$.validator.addMethod('date',
    function (value, element) {
        return true; // since MVC4 data-val-date is put on EVERY vm date property. Default implementation does not allow for multiple cultures...
    });

You can also try to write your own editor template named "DateTime.cshtml" in your shared EditorFor folder, but don't use TextBoxFor there, because that one is polluted as well.
