Comentarios

Si está suscrito, este evento se genera cada vez que se crea una instancia de la actividad secundaria para un elemento en la colección Children. La colección Children se establece a través de ReplicatorChildEventArgs del controlador de eventos Initialized. La instancia Activity secundaria se pasa en la llamada de manera que ReplicatorActivity podrá establecer valores en el elemento secundario. También se pasa el objeto InstanceData relevante de la colección Children.
