MVC3 Validation using data annotations

I recently created a contact form for my latest project bankrutt.se

I used a model for my contact entity and the view was auto-generated nicely.
One thing that struck me was that the form only validated if any text was entered, how about e-mail validation?

It seems that you would have to create your own regular expression validation using [RegularExpression(“####”)]
This seems fair enough but I am to lazy for that!
A quick google lead me to this blog.

Downloading the the GitHub package Install-Package DataAnnotationsExtensions.MVC3
DataAnnotationsExtensions.MVC3

You could with no effort achieve the same thing using the attribute

[Email] 

(like in the example below)

The currently available validators are:

CreditCard
Date
Digits
Email
EqualTo
FileExtensions
Integer
Max
Min
Numeric
Url

public class Contact
    {
 [Required(ErrorMessage = "Du måste ange din e-postadress")]
        [Email(ErrorMessage="Felaktig e-postadress")]
        [DataType(DataType.EmailAddress)]
        public string From { get; set; }

        [Required(ErrorMessage = "Du måste ange rubrik")]
        public string Subject { get; set; }


        [DataType(DataType.MultilineText)]
        [Required(ErrorMessage = "Du måste skriva ett meddelande")]
        public string Message { get; set; }
}

This is more how it should be!
This works for both server and client side validation as well.
