Remarks
This property is used by the UpdateCommand during the DbDataAdapter.Update to determine whether the original or current value is used for a parameter value. This lets primary keys be updated. This property is set to the version of the DataRow used by the DataRow.Item[] property (DataRow indexer), or the DataRow.GetChildRows method of the DataRow object.
