Keterangan

Jika properti ini diatur secara terprogram, properti tidak bertahan kecuali properti diatur secara dinamis pada setiap permintaan. Jika properti diatur secara deklaratif, properti diatur pada setiap permintaan. Tidak ada default.

Karena perangkat yang berbeda memiliki persyaratan gaya yang berbeda. Anda mungkin menginginkan beberapa DeviceSpecific pengaturan untuk CommandStyle properti .
