Comentários

Se inscrito, esse evento é gerado sempre que uma instância da atividade filho é criada para um item na Children coleção. A Children coleção é definida por meio do ReplicatorChildEventArgs manipulador de Initialized eventos. A instância filho Activity é passada na chamada para que o ReplicatorActivity possa definir valores no filho. O objeto relevante InstanceData da Children coleção também é passado.
