Hi, I am using MVC on my form and my Model is as follows

C#

 [Required(ErrorMessage = "E-mail must be entered")]
[DataType(DataType.EmailAddress,ErrorMessage="invalid")]
public string UserName { get; set; }

Its is checking validation against Required attribute but not against datatype. Could anyone explain why? Added reference to DataAnnotation.dll, overrided IsValid method of RegularExpressionAttribute class... No results.. huh
Thank you.

Solution 1

[DataType(DataType.EmailAddress,ErrorMessage="invalid")]

This is not sufficient to set a validation on a field.
For email validation, use regular expressions as validation.

http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx[^] is a good example on email validation.

Solution 4

[RegularExpression(@"^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@([A-Za-z0-9]+)(([\.\-‌]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$", ErrorMessage = "Email is not valid")]

Solution 2

Apparently this works:

C#

using System.ComponentModel.DataAnnotations;
    [Required]
    [EmailAddress]
    public String Email { get; set; }

I am unable to use [EmailAddress] in my project

Christian Graus 23-Jan-14 4:26am

Then you either need to add a reference, use a newer MVC version, or use regex :)

I have added reference to DataAnnotation, new version not possible as project is older, no regex is working, I already tried 20-25 working regexes :(

Christian Graus 23-Jan-14 4:40am

Don't try 20-25. They ALL work. Work out why none of them work when you use them wrong.

I have already made lot of efforts, you can see updated question.

Christian Graus 23-Jan-14 4:47am

Well, I don't doubt it, but you shouldn't try 25 different regexes. You should take one, and make it work. Clearly your code, not the regex, is the issue.

Is something breaking javascript in your page, so that the validation js does not run ?
