Ejemplos

En el ejemplo de código siguiente se muestra cómo crear un ImageMap control mediante programación y agregar dos CircleHotSpot objetos a él. La HotSpots propiedad se usa para tener acceso HotSpotCollectionImageMap al control y agregarle los CircleHotSpot objetos. Para que este ejemplo funcione correctamente, debe proporcionar su propia imagen para la ImageUrl propiedad y actualizar la ruta de acceso a la imagen correctamente para que la aplicación pueda localizarla.
