C#-4.0 Winforms inherited/sub-classed Button control OnClick not firing

In C# Winforms inherited/sub-classed Button control subscribing to OnMouseDown, OnMouseUp OnPaint and OnClick events. public class MyControl : Button The OnClick Event will not fire within the control or pass to the parent control the raised event. As soon as the the subclass is changed to type UserControl the OnClick event becomes active and the OnMouseDown, OnMouseUp, OnPaint events stop working within the control let alone within the parent. What can be done to force the control class to subscribe to the button control subclass's events when using the overrides? Supplied is the entire Class.

As you can see I have a MessageBox in the Controls OnClick event and the message never shows.

       [Description("On Click event")]
        protected override void OnClick(EventArgs e)
        {
            base.OnClick(e);
            MessageBox.Show("Button Clicked");
 //This Message will only appear if the subclass is set to USERCONTROL
        }

Thanks in advance for any responses.
