Set DrawMode property and handle DrawItem event of ListBox,

 private void Form1_Load(object sender, EventArgs e)
        {
            listBox1.DrawMode = DrawMode.OwnerDrawVariable;
            listBox1.Items.Add("One");
            listBox1.Items.Add("Two");
            listBox1.Items.Add("Three");
            listBox1.DrawItem += new DrawItemEventHandler(listBox1_DrawItem);    
        }

        void listBox1_DrawItem(object sender, DrawItemEventArgs e)
        {
            ListBox l=sender as ListBox;
            e.DrawBackground();
            e.DrawFocusRectangle();
            e.Graphics.DrawEllipse(Pens.Blue, new Rectangle(1, 1+e.Index * 15, 100, 10));
            e.Graphics.DrawString(l.Items[e.Index].ToString(), new Font(FontFamily.GenericSansSerif,9, FontStyle.Regular), Brushes.Red , e.Bounds);
        }
