Question

I am using the spark viewengine, asp.net mvc, and .resx files.

I want to set a language through my custom SessionModel (Session) which is registered through Castle.Windsor and has a string property of Culture which can be set by the user…

I need the current language to persist on every view, without having to constantly set the current UICulture.

Not having to do this everytime in each Controller Action:

    public SessionModel SessionModel { get; set; }

    public ActionResult Index()
    {
        Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SessionModel.Culture);
        Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;
    }

The problem with doing it this way, is if I go onto another page the current culture will flip back to the default language.

On the spark view I simply call, to obtain the current Culture:

${SR.Home}

SR.resx contains a public entry for Home.

Does anyone have a good idea of how to do this, should I do this with an ActionFilter?

Answer 1

Action filter seems like a good idea:

public class SetCultureActionFilterAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        CultureInfo culture = FetchCultureFromContext(filterContext);
        Thread.CurrentThread.CurrentCulture = culture;
        Thread.CurrentThread.CurrentUICulture = culture;
        base.OnActionExecuting(filterContext);
    }

    private CultureInfo FetchCultureFromContext(ActionExecutingContext filterContext)
    {
        throw new NotImplementedException();
    }
}

and then decorate your base controller with this attribute.
