关于获取Gridcontrol中repositoryItemLookUpEdit的使用

//数据源绑定注意事项：//1、repositoryItemLookUpEdit绑定，DisplayMember和ValueMember  必须绑定同一个字段//2、repositoryItemLookUpEdit绑定的字段名称和Gridcontrol里面对应的字段名称必须一致//根据ValueMember的值  查找repositoryItemLookUpEdit里面的其它值  并赋值private void lupUser_EditValueChanged ( object sender ,System . EventArgs e )        {            DevExpress . XtraEditors . BaseEdit edit = gridView1 . ActiveEditor;            switch ( gridView1 . FocusedColumn . FieldName )            {                case "ARP001":                string str = tablePerson . Select ( "ARP001='" + edit . EditValue + "'" ) [ 0 ] [ "ARP002" ] . ToString ( );               gridView1 . SetFocusedRowCellValue ( gridView1 . Columns [ "ARP002" ] ,edit . EditValue );                break;            }        }//或者在gvDetailMateriel_CellValueChanging事件里面做(DataRowView)itemlookUpEdit.GetDataSourceRowByKeyValue(e.Value)).Row
