The RowUpdating event is raised before an Update to a row.

When using Update, there are two events that occur for each data row updated. The order of execution is as follows:

  1. The values in the DataRow are moved to the parameter values.

  2. The OnRowUpdating event is raised.

  3. The command executes.

  4. If the command is set to FirstReturnedRecord, then the first returned result is placed in the DataRow.

  5. If there are output parameters, they are placed in the DataRow.

  6. The OnRowUpdated event is raised.

  7. AcceptChanges is called.
