How to handle ASP.NET Update Panel in WatiN

Handling asp.net update panels with WatiN is a pretty annoying thing.
Click and WaitForLoad usually throws timeout every time.

I have found "just fine" solution that work for me:

static class ElementExtension
    {
        public static void ActWithToken(this Element Element, Action Action)
        {
            string Waittoken = "waittoken";
            Element.SetAttributeValue(Waittoken, Waittoken);
            Action();
            Element.WaitUntil(!Find.By(Waittoken, Waittoken));
        }
        
        public static void ActWithToken<E>(this E Element, Action<E> Action)
            where E : Element 
        {
            string Waittoken = "waittoken";
            Element.SetAttributeValue(Waittoken, Waittoken);
            Action(Element);
            Element.WaitUntil(!Find.By(Waittoken, Waittoken));
        }
    }
