Keterangan
PreviousViewCommandName Gunakan bidang untuk mewakili nama perintah "PrevView".
Anda dapat menggunakan nilai bidang ini untuk memanfaatkan MultiView pembaruan otomatis kontrol kontrol View . Misalnya, jika View kontrol berisi Button kontrol yang menavigasi ke berikutnya View, Anda dapat mengatur CommandName properti ke nilai PreviousViewCommandName bidang , yaitu "PrevView". Ini menyebabkan MultiView kontrol secara otomatis menambah nilai ActiveViewIndex properti saat tombol diklik.
