DBDataSetCommand.OnRowUpdated

Raises the OnRowUpdated event.

[Visual Basic]
MustOverride Protected Sub OnRowUpdated( _
   ByVal ruevent As RowUpdatedEventArgs _
)
[C#]
protected abstract void OnRowUpdated(
   RowUpdatedEventArgs ruevent
);
[C++]
protected: virtual void OnRowUpdated(
   RowUpdatedEventArgs* ruevent
) = 0;
[JScript]
protected abstract function OnRowUpdated(
   ruevent : RowUpdatedEventArgs
);

Parameters

ruevent
A ADORowUpdatedEventArgs that contains the event data.

Remarks

Raising an event invokes the event-handling method through a delegate. For an overview, see TBD.

Notes to Inheritors: When overriding OnRowUpdated in a derived class, be sure to call the base class's OnRowUpdated method.

Example [Visual Basic]

The following example uses this method within a derived class.

[Visual Basic]

' MyDataSetCommand.class derived from ADODataSetCommand
Inherits ADODataSetCommand
' create the method for row updated
Public Sub OnRowUpdated(event As RowUpdatedEventArgs)
   ' show a message box telling user of row update
   Dim myMsgBox As MessageBox
   myMsgBox.Show "A row has been updated."
   '  call the base class method
   MyBase.OnRowUpdated event
End Sub
' create the method for row updating
Public Sub OnRowUpdating(event As RowUpdatingEventArgs)
   ' show a message box telling user of row update
   Dim myMsgBox As MessageBox
   myMsgBox.Show "A row is being updated ..."
   '  call the base class method
   MyBase.OnRowUpdating event
End Sub
' create the method for the schema changing
Public Sub OnSchemaChanging(event As SchemaChangingEventArgs)
   ' show a message box telling user of schema change
   Dim myMsgBox As MessageBox
   myMsgBox.Show "The schema is changing ..."
   '  call the base class method
   MyBase.OnSchemaChanging event
End Sub
' create the method for the schema changed
Public Sub OnSchemaChanged(event As SchemaChangedEventArgs)
   ' show a message box telling user of schema change
   Dim myMsgBox As MessageBox
   myMsgBox.Show "The schema has changed"
   '  call the base class method
   MyBase.OnSchemaChanged event
End Sub
' create the method for the schema being mapped
Public Sub OnSchemaMapping(event As SchemaMappingEventArgs)
   ' show a message box telling the user of schema map
   Dim myMsgBox As MessageBox
   myMsgBox.Show "The schema is currently being mapped ..."
   ' call the base class method
   MyBase.OnSchemaMapping event
End Sub
