Açıklamalar

Bu özellik program aracılığıyla ayarlandıysa, özellik her istekte dinamik olarak ayarlanmadığı sürece kalıcı olmaz. Özellik bildirim temelli olarak ayarlanırsa, özellik her istekte ayarlanır. Varsayılan değer yoktur.

Farklı cihazların stiller için farklı gereksinimleri olduğundan. Özellik için CommandStyle birkaç DeviceSpecific ayar isteyebilirsiniz.
