Use IndexName to specify an alternative index for a client dataset. If IndexName is empty, the dataset抯 sort order is based on the IndexFieldNames property or on its default ordering in the data packet. Default ordering is determined by the predefined index, DEFAULT_ORDER.
If IndexName contains a valid index name, then that index is used to determine sort order of records.
Note: IndexFieldNames and IndexName are mutually exclusive. Setting one clears the other.
