Details

If you modify the current row in the table, you must use the _updateRow method before calling the _getRow method.

After calling _getRow, you can use the _getColumnText and _getColumnValue methods of the Data Set Model class or the _getText and _getValue methods of the Data Set Data Vector class to retrieve the values read from the table.

The _getRow method sets SYSRC for error, note, and warning conditions.
