I have some problems with the validation of a Email.

In my Model:

[Required(ErrorMessage = "Field can't be empty")]
[DataType(DataType.EmailAddress, ErrorMessage = "E-mail is not valid")]
public string ReceiverMail { get; set; }

In my view:

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@Html.TextBoxFor(m => m.ReceiverMail, new { @placeholder="E-mail"}) <br />
@Html.ValidationMessageFor(m => m.ReceiverMail)

Now it is correctly showing me "Field can't be empty" when you leave the field empty. But when you fill in an invalid email address like: "fwenrjfw" then the form does not say "E-mail is not valid".

How can I get the form to validate the input as an email address? I am looking for some help with this.

If you are using .NET Framework 4.5, the solution is to use EmailAddressAttribute which resides inside System.ComponentModel.DataAnnotations.

Your code should look similar to this:

[Display(Name = "Email address")]
[Required(ErrorMessage = "The email address is required")]
[EmailAddress(ErrorMessage = "Invalid Email Address")]
public string Email { get; set; }
