The RowUpdated event is raised when an Update to a row is completed.
When using Update, there are two events that occur for each data row updated. The order of execution is as follows:
The values in the DataRow are moved to the parameter values.
The OnRowUpdating event is raised.
The command executes.
If the command is set to FirstReturnedRecord, and the first returned result is placed in the DataRow.
If there are output parameters, they are placed in the DataRow.
The OnRowUpdated event is raised.
AcceptChanges is called.
The following example shows how to use both the RowUpdating and RowUpdated events.
The RowUpdating event returns this output:
Event Arguments: (command=System.Data.SqlClient.SqlCommand commandType=2 status=0)
The RowUpdated event returns this output:
Event Arguments: (command=System.Data.SqlClient.SqlCommand commandType=2 recordsAffected=1 row=System.Data.DataRow[37] status=0)
