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

    When using the System.Data.Common.DbDataAdapter.Update() method, there are two events that occur for each data row updated: MySqlDataAdapter.RowUpdating and MySqlDataAdapter.RowUpdated. The order of execution for an update operation is as follows:

    1. The values in the System.Data.DataRow are moved to the parameter values.
    2. The MySqlDataAdapter.RowUpdating event is raised.
    3. The command executes.
    4. If the System.Data.UpdateRowSource enumeration is set to System.Data.UpdateRowSource.FirstReturnedRecord, the first returned result is placed in the System.Data.DataRow.
    5. If there are output parameters, they are placed in the System.Data.DataRow.
    6. The MySqlDataAdapter.RowUpdated event is raised.
    7. System.Data.DataRow.AcceptChanges is called.
