The UniDataAdapter.RowUpdating event is raised before an update to a row.

The values in the System.Data.DataRow are moved to the parameter values.
The UniDataAdapter.RowUpdating event is raised.
The command executes.
If the System.Data.UpdateRowSource enumeration is set to System.Data.UpdateRowSource.FirstReturnedRecordS, the first returned result is placed in the System.Data.DataRow.
If there are output parameters, they are placed in the System.Data.DataRow.
The UniDataAdapter.RowUpdated event is raised.
System.Data.DataRow.AcceptChanges is called.
