Using dataGridView1_EditingControlShowing we can do this.

        {
            ComboBox dgvCombo = e.Control as ComboBox;
            if (dgvCombo != null)
            {
                // first remove event handler to keep from attaching multiple:
                dgvCombo.SelectedIndexChanged -= new  EventHandler(dvgCombo_SelectedIndexChanged);

                // now attach the event handler
                
                dgvCombo.SelectedIndexChanged += new EventHandler(dvgCombo_SelectedIndexChanged);

            }

        }

        private void dvgCombo_SelectedIndexChanged(object sender, EventArgs e)
        {
            MessageBox.Show("Now Selected index changed");
        }
