Answer 1

If you are using WPF, you might be able to use RaiseEvent: http://msdn.microsoft.com/en-us/library/system.windows.uielement.raiseevent.aspx

But this is wrong for what you want to do.

You should bubble the event.

class MyControl : UserControl {
    public KeyDownEventHandler KeyDown;

    private void OnTextBoxKeyDown(object sender, EventArgs e){ KeyDown.Invoke(sender, e); }
}

Then listen to KeyDown from your form. Please excuse mistakes in the naming of the various elements / events.
