Validating with localized strings

Question

I am trying to localize validation messages in an ASP MVC3 model class.

[RegularExpression(@"^\d*$", ErrorMessage = "Has to be numeric.")]
public Int32? X{ get; set; }

We have to retrieve the localized strings from a database using a method from a given resource handler, so no common resource files are possible.

What is the prefered way to do this?

Thanks in advance!

You can set the resource key on the vaildation attribute, along with the resource type (RESX).

Required(ErrorMessageResourceName = "Required", 
           ErrorMessageResourceType = typeof(Resources.Validation))]
[DataType(DataType.Text)]
public string Name { get; set; }

Note one limitation is if you are using a custom resource provider. Unfortunately there's is no provision to plug this in. I came up with solution for this here, but if you are using standard RESX approach then it's not necessary.
