Ejemplos

El código de ejemplo siguiente proporciona un método que asocia un controlador de eventos para el ComponentsCreated evento de .ToolboxItem También proporciona un ToolboxComponentsCreatedEventHandler método de controlador de eventos que escribe el nombre del tipo de los componentes que se crearon en cuando Console un evento genera ComponentsCreated el controlador de eventos.

public:
   [PermissionSetAttribute(SecurityAction::Demand, Name="FullTrust")]
   void LinkToolboxComponentsCreatedEvent( ToolboxItem^ item )
   {
      item->ComponentsCreated +=
         gcnew ToolboxComponentsCreatedEventHandler( this, &Form1::OnComponentsCreated );
   }

private:
   void OnComponentsCreated( Object^ sender, ToolboxComponentsCreatedEventArgs^ e )
   {
      // Lists created components on the Console.
      for ( int i = 0; i < e->Components->Length; i++ )
      {
         Console::WriteLine( "Component #" + i + ": " +
            e->Components[ i ]->Site->Name );
      }
   }

public void LinkToolboxComponentsCreatedEvent(ToolboxItem item)
{
    item.ComponentsCreated += new ToolboxComponentsCreatedEventHandler(this.OnComponentsCreated);
}

private void OnComponentsCreated(object sender, ToolboxComponentsCreatedEventArgs e)
{
    // Lists created components on the Console.
    for( int i=0; i< e.Components.Length; i++ )
        Console.WriteLine("Component #"+i.ToString()+": "+e.Components[i].Site.Name.ToString());            
}

Public Sub LinkToolboxComponentsCreatedEvent(ByVal item As ToolboxItem)
    AddHandler item.ComponentsCreated, AddressOf Me.OnComponentsCreated
End Sub

Private Sub OnComponentsCreated(ByVal sender As Object, ByVal e As ToolboxComponentsCreatedEventArgs)
    ' Lists created components on the Console.
    Dim i As Integer
    For i = 0 To e.Components.Length - 1
        Console.WriteLine(("Component #" + i.ToString() + ": " + e.Components(i).Site.Name.ToString()))
    Next i
End Sub

Comentarios

Al crear un ToolboxComponentsCreatedEventHandler delegado, se identifica el método que controlará el evento. Para asociar el evento con el controlador de eventos, agregue una instancia del delegado al evento. Se llama al controlador de eventos cada vez que se produce el evento, a menos que quite el delegado. Para obtener más información sobre los delegados del controlador de eventos, consulte Control y generación de eventos.
