Asp.Net Register Global Custom Filter Not Having [ChildAactionOnly] attribute

Question

I know how to Register Global filter that applies all actions with:

protected void Application_Start(){
    GlobalFilters.Filters.Add(new MySweetCustomFiAttribute());
}

But instead, I need to register MySweetCustomFilterAttribute to actions not having (or having) [ChildActionOnly] attribute.

    // Register MySweetCustomFilterAttribute
    public ActionResult Index()
    {
       return View();
    }

   // Do not register MySweetCustomFilterAttribute
   [ChildActionOnly]
   public ActionResult MySweetChildAction()
    {
      ...
    }

Answer 1

You should put a bypass into your [MySweetCustomFiAttribute] to return if the action is decorated with [ChildActionOnly]. Like this:

if(filterContext.ActionDescriptor.IsDefined(typeof(ChildActionOnlyAttribute), false))
    return;
