Hello!

I've setup our Umbraco site to use translations. This works fine in my templates. Now I'm trying to add the translations in my viewmodels. These viewmodels contain validations messages in attributes (standard MVC validation).

My current approach in to set the key in the ErrorMessage of the property, like so:

[Required(ErrorMessage = "MyKey")]
public string UserName { get; set; }

Then in the OnActionExecuting override method in my SurfaceController I'm replacing the keys in the ErrorMessages by the actual value of the key:

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
    ModelState.Values.ToList().ForEach(e =>
    {
        var allErrorKeys = e.Errors.Select(x => x.ErrorMessage).ToArray();
        e.Errors.Clear();
        foreach (string errorKey in allErrorKeys)
        {
            var item = Services.LocalizationService.GetDictionaryItemByKey(errorKey);
            e.Errors.Add(item.Translations.ToList()[0].Value);
        }
    });
}

Although this code needs some refactoring, it works.

But I'm not so happy with this code, it's hacky... Is there an out of the box way of translating messages in viewmodels? Any other suggestions at all?

Thanks!
