public partial class Form5 : Form
    {
        public Form5()
        {
            InitializeComponent();
        }

        private void Form5_Load(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("aa");
            dt.Columns.Add("bb");
            for (int i = 0; i < 10; i++)
            {
                dt.Rows.Add("aa" + i, "bb" + i);
            }
            dt.AcceptChanges();
            this.listBox1.DisplayMember = "bb";
            this.listBox1.DataSource = dt;
            this.listBox1.Height = 200;
            this.listBox1.MouseDoubleClick += new MouseEventHandler(listBox1_MouseDoubleClick);
        }

        void listBox1_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            int index = this.listBox1.IndexFromPoint(e.Location);
            if (index != System.Windows.Forms.ListBox.NoMatches)
            {
                MessageBox.Show(index.ToString());
                //do your stuff here
            }
