Extending the ListBox Control to allow BorderColor

I'm trying to extend the ListBox Control and allow the property BorderColor. It appears the OnPaint event isn't triggering. I roughly know how to draw a single border but of course it isn't appearing. I would like to apply the BorderColor and BorderStyle to make a border, I tried this but it has an error where DrawBorder accepts an argument of type ButtonBorderStyle but a ListBox has a property type of BorderStyle. So I'm very confused of how I can go about doing this.

Here is my current code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using System.Drawing;

namespace ListBoxPlus
{
    public class ListBoxPlus : ListBox
    {
        private Color borderColor = SystemColors.ControlDark;

        public Color BorderColor
        {
            get
            {
                return this.borderColor;
            }
            set
            {
                this.borderColor = value;
                this.Invalidate();
            }
        }

        public ListBoxPlus() { }

        protected override void OnPaint(PaintEventArgs e)
        {
            // breakpoint on the below line doesn't happen
            base.OnPaint(e);

            //ControlPaint.DrawBorder(e.Graphics, this.ClientRectangle, this.borderColor, this.BorderStyle);
            Pen pen = new Pen(this.borderColor);

            e.Graphics.DrawRectangle(pen, 0, 0, this.Width - 1, this.Height - 1);
        }
    }
}
