List Area method

Can you please tell me why this routine is not showing values in the text box when i click in the text area?

      private void listBox2_SelectedIndexChanged(object sender, EventArgs e)
        {
            ListBox i = sender as ListBox;
            if (i.SelectedIndex != -1)
            {
                listBox1.SelectedIndex = i.SelectedIndex;
                listBox2.SelectedIndex = i.SelectedIndex;
                txtID.Text = listBox1.SelectedItem.ToString();
                txtName.Text = listBox2.SelectedItem.ToString();               
            }
        
        }
