Represents the method that will handle the RowUpdating event of a DB2DataAdapter.
[Visual Basic]
<Serializable>
Public Delegate Sub DB2RowUpdatingEventHandler( _
ByVal sender As Object, _
ByVal e As DB2RowUpdatingEventArgs _
)
[C#]
[Serializable]
public delegate void DB2RowUpdatingEventHandler(
object sender,
DB2RowUpdatingEventArgs e
);
[C++]
[Serializable]
public __gc __delegate void DB2RowUpdatingEventHandler(
Object* sender,
DB2RowUpdatingEventArgs* e
);The handler is not required perform any action, and your code should avoid generating exceptions or allowing exceptions to propagate to the calling method. Any exceptions that do reach the caller are ignored.
Use the handler to process DB2RowUpdatingEventArgs and to specify how updates are processed. For example, you may opt to skip the update of the current row or skip the update of all remaining rows. Note that the rows are updated in the order that they were received from the database.
When you create a DB2RowUpdatingEventArgs delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see "Events and Delegates" in the .NET Framework SDK documentation.
