DataGridView下拉列表联动

找的时候费了很大的劲,特别记录一下

private void dgvServiceItem_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
            DataGridView dgvTemp = (DataGridView)sender;
            if (dgvTemp.CurrentCell.RowIndex != -1 && dgvTemp.CurrentCell.ColumnIndex == 1)
            {
                ((ComboBox)e.Control).SelectedIndexChanged += new EventHandler(FrmAddPackage_SelectedIndexChanged);
            }
        }

        private void FrmAddPackage_SelectedIndexChanged(object sender, EventArgs e)
        {
            ComboBox cbTemp = (ComboBox)sender;
            cbTemp.SelectedIndexChanged -= new EventHandler(FrmAddPackage_SelectedIndexChanged);
        }

这种方式绑定数据源的时候有问题
