Keterangan

Jika berlangganan, peristiwa ini dinaikkan setiap kali instans aktivitas anak dibuat untuk item dalam Children koleksi. Koleksi Children diatur melalui ReplicatorChildEventArgs penanganan Initialized aktivitas. Instans anak Activity diteruskan dalam panggilan sehingga ReplicatorActivity dapat mengatur nilai pada anak. Objek yang relevan InstanceData dari Children koleksi juga diteruskan.
