Localizing MVC 3 client side validation messages

I'm working on an ASP.Net MVC 3 project, which needs localized error messages from its validation rules.

Is there any way to do this client side ?

I can live with english serverside validation messages, as the client side ones should always be triggered (I've no fear my users will disable javascript, as it's an Intranet site)

Whilst I can use DataAnnotations for stuff such as [Required] and [StringLength], there is no such option (it seems) for data type validation.

If for instance I have int Portions in my view model, it's automatically validate input to ensure it's an int. Fair enough, but the validation message is always in english :-(

Suppose my model looks like this:

public class RecipeModel
{

[Display(Name = "Navn")]
[Required(ErrorMessage = "Skal udfyldes")]
public string Name { get; set; }

[Display(Name = "Portioner")]
public int Portions { get; set; }

}

As you can see I have a custom errormessage for "Name", however if I try to enter text into the EditorFor(Portions), it'll show my this errormessage:

"The field Portioner must be a number."

And that's the errormessage I want to localize. Unfortunately there's no DataAnnotation for that built-in validator (checking that it's an int).

I even tried using a DataType annotation of type Custom, to no avail :-(

You can create your own validation messages using data annotations with your model. If you want to support multiple languages you can create a resource file for each language and link from the data annotation to the Id of the message in your resource file.
