Email model validation with DataAnnotations and DataType
Solution 1
DataType
attribute is used for formatting purposes, not for validation.
I suggest you use ASP.NET MVC 3 Futures for email validation.
Sample code:
[Required]
[DataType(DataType.EmailAddress)]
[EmailAddress]
public string Email { get; set; }
If you happen to be using .NET Framework 4.5
, there's now a built in EmailAddressAttribute
that lives in System.ComponentModel.DataAnnotations.EmailAddressAttribute
.
Solution 2
The DataAnnotationsExtensions project has an Email attribute that you can use.
Solution 3
I have looked at the source code (reverse engineered by Reflector) and DataType
variants are actually not even implemented! (This was for DateType.Date
)
So it is not going to work.
I would personally use RegexValidation
for email.
For clarity, here is the implementation of IsValid
in class DataTypeAttribute
:
public override bool IsValid(object value)
{
return true;
}

I have following model:
public class FormularModel { [Required] public string Position { get; set; } [Required] [DataType(DataType.EmailAddress)] public string Email { get; set; } [Required] public string Webcode { get; set; } }
Required validation works fine. But when i try with DataType it doesn't react.
Here is my razor code for the email control:
@Html.TextBoxFor (model => model.Email, new { @style = "width: 175px;", @class = "txtField" } ) *
So, anyone know an answer?
TIA
