Infragistics组件-UltraGrid删除行的陷阱

遍历选中行，从数据库和内存中删除选中行对象，如下所示：

            foreach (var row in dataDictGrid.Selected.Rows)
            {
                MDataDictionary data = row.ListObject as MDataDictionary;
                if (data != null && data.ObjectID > 0)
                {
                    _bslDataDict.DeleteDataDictionary(data);
                    row.Delete(false); //陷阱！破坏集合
                }              
            }

正确做法：

            //先从数据库中删除
            foreach (var row in dataDictGrid.Selected.Rows)
            {
                MDataDictionary data = row.ListObject as MDataDictionary;
                if (data != null && data.ObjectID > 0)
                {
                    _bslDataDict.DeleteDataDictionary(data);
                }              
            }
            //再从内存中一次性删除选中行对象的list
            dataDictGrid.DeleteSelectedRows(false);
