Esempio

Nell'esempio di codice seguente viene illustrato come creare due CircleHotSpot oggetti a livello di HotSpotCollectioncodice, impostare le proprietà e aggiungerle al ImageMap controllo . Per il corretto funzionamento di questo esempio, è necessario specificare la propria immagine per la ImageUrl proprietà e aggiornare il percorso dell'immagine in modo appropriato in modo che l'applicazione possa individuarla.
