Localizing MVC3 Validation Messages

Question

I'm trying to localize the validation messages of the data-annotations. I thought that it could be done as described here: Supporting ASP.NET MVC 3 Validation with Non-English Locales.

Now it says that ASP.NET MVC and types in the System.ComponentModel.DataAnnotations namespace use their own localized messages. So is that more or less useless to me and only a help for formatting for example prices?

But back to the real question, so the only way to localize the validation messages is doing something like this? localize default model validation in mvc 2

Just trying to get some clearification here, thanks =)

Answer 1

The resources for the data annotations are in the .NET Framework 4. You have to install the language pack for the .NET Framework.

Answer 2

You could use resource files:

public class UserViewModel
{
    [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(UserResources))]
    [Display(Name = "FirstName", ResourceType = typeof(UserResources))]
    public string FirstName { get; set; }
}
