Delay in Silverlight

public class ActionDispatcherTimer : System.Windows.Threading.DispatcherTimer
{
    public Action Action { get; set; }
}

public static class UIHelper
{
    public static void DelayStart(int milliseconds, Action action)
    {
        var timer = new ActionDispatcherTimer
                        {
                            Interval = new TimeSpan(0, 0, 0, 0, milliseconds),
                            Action = action
                        };
        timer.Tick += onTick;
        timer.Start();
    }

    private static void onTick(object sender, EventArgs arg)
    {
        var t = sender as ActionDispatcherTimer;
        t.Stop();
        t.Action();
        t.Tick -= onTick;
    }
}

//usage: after 5 seconds execute ths lambda
UIHelper.DelayStart(5000, () => status = "Completed");
