Esempio di codice seguente viene illustrato come utilizzare il ISupportInitialize interfaccia da inizializzare tre TrackBar controlli.The following code example demonstrates how to use the ISupportInitialize interface to initialize three TrackBar controls.

Commenti

ISupportInitialize consente ai controlli di ottimizzare più assegnazioni di proprietà.ISupportInitialize allows controls to optimize multiple property assignments. Di conseguenza, è possibile inizializzare le proprietà di CO-dipendenti o batch imposta più proprietà in fase di progettazione.As a result, you can initialize co-dependent properties or batch set multiple properties at design time.

Chiamare il BeginInit metodo per segnalare l'oggetto avvio dell'inizializzazione.Call the BeginInit method to signal the object that initialization is starting. Chiamare il EndInit metodo per segnalare che l'inizializzazione è stata completata.Call the EndInit method to signal that initialization is complete.

Metodi

BeginInit() BeginInit() BeginInit() BeginInit()

Segnala all'oggetto l'avvio dell'inizializzazione.Signals the object that initialization is starting.

EndInit() EndInit() EndInit() EndInit()

Segnala all'oggetto che l'inizializzazione è completa.Signals the object that initialization is complete.
