Occurs during Update after a command is executed against the data source. The attempt to update is made, so the event fires.

[Visual Basic]
Public Event RowUpdated As SqlRowUpdatedEventHandler
[C#]
public event SqlRowUpdatedEventHandler RowUpdated;
[C++]
public: __event SqlRowUpdatedEventHandler* RowUpdated;

[JScript] In JScript, you can handle the events defined by a class, but you cannot define your own.

Event Data

The event handler receives an argument of type SqlRowUpdatedEventArgs containing data related to this event. The following SqlRowUpdatedEventArgs properties provide information specific to this event.

Remarks

When using Update, there are two events that occur per 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.

Example

[Visual Basic, C#, C++] The following example shows how to use both the RowUpdating and RowUpdated events.

[Visual Basic, C#, C++] The RowUpdating event returns this output:

[Visual Basic, C#, C++] event args: (command=System.Data.SqlClient.SqlCommand commandType=2 status=0)

[Visual Basic, C#, C++] The RowUpdated event returns this output:

[Visual Basic, C#, C++] event args: (command=System.Data.SqlClient.SqlCommand commandType=2 recordsAffected=1 row=System.Data.DataRow[37] status=0)
