namespace WindowsFormsApplication1
{
    public partial class CustomControl1 :ListBox
    {
        public CustomControl1()
        {
            InitializeComponent();
        }

        protected override void OnPaint(PaintEventArgs pe)
        {
            base.OnPaint(pe);
        }
    }
}

------解决方案--------------------

ListBox的OnPaint声明为


C# code

    [EditorBrowsable(EditorBrowsableState.Never), Browsable(false)]
    public event PaintEventHandler Paint;

.NET Framework 版本有关
