Question

I am using the following in my model for a date control

   [DataType(DataType.DateTime)]
   public DateTime txtDateAppCompletion { get; set; }

I also tried DataType.Date as I only want a date input.

   [DataType(DataType.Date)]
   public DateTime txtDateAppCompletion { get; set; }

For some reason when I run the form and I type anything that is not a date it does not validate it, not on server or on client(client validation is enabled).

Any Idea why I am having this problems? How to solve it?

Answer 1

Ok, after some research I found this in a Microsoft book.

■ Caution Even though [DataType] looks
like a validation attribute along with
the others in Data Annotations,
ASP.NET MVC does not treat it as one,
so don’t expect
[DataType(DataType.EmailAddress)] to
validate for legal e-mail addresses!
[DataType] is an anomaly; even though
it inherits from
System.ComponentModel.DataAnnotations.ValidationAttribute,
its IsValid() method is hard-coded to
return true regardless of the
property’s value. Microsoft has
explained that [DataType] is only
meant to serve as a hint for
formatting data in a scaffolded UI…
