Default Custom event not firing


I have a problem with custom controls and raising events (asp.net, vs2005, frameowork 2.0).
I am making a simple TestControl to learn how custom controls work.
Most things went fine, but now I ran into a problem that
a custom event is not fired. See code piece below.
I have commented the lines that cause the problem.

Problem: for some reason, the event-declaration is not executed,
so 'MyEvent' is always null, and thus the event is not fired.
But the question is: why is the declaration not executed (why is 'MyEvent' is always null)
and what can I do about it?

Can anybody help me please?

************************************************** **********************

namespace TestControl
    [ToolboxData("<{0}:TestControl runat=server></{0}:TestControl>")]

    public class TestControl : WebControl, IPostBackDataHandler, IPostBackEventHandler

        // ----------------------------------------------
        // Declare delegate for event
        public delegate void EventDelegate (Object sender, EventArgs e);
        public event EventDelegate MyEvent; // *** This line is not executed. why?

        protected virtual void OnMyEvent(EventArgs e)
            if (MyEvent != null) MyEvent(this, e); // *** here, MyEvent is null. Why?

        // ----------------------------------------------
        public void RaisePostBackEvent(String eventArgument)

            if (eventArgument == "Add")

                EventArgs e = new EventArgs();
        // ----------------------------------------

        protected override void OnInit(EventArgs e)

        // ---------------------------------------


    } // end of classs
