Question

public class RegisterModel
    {
        [Required]
        [Display(Name = \"Email Add         


        

Answer 1

DataType alone will not trigger any server-side validation. But, since MVC 4 using DataType.EmailAddress will make the HTML input use type="email", which in turn makes jQuery Validation perform Regex validation on the client.

.NET 4.5 introduced the [EmailAddress] attribute, a subclass of DataTypeAttribute. By using [EmailAddress] you get both client and server side validation.
