كيفية القيام بما يلي: تعريف نطاق اسم

لاستخدام Storyboard للتحريك في التعليمات البرمجية، يجب إنشاء NameScope وتسجيل أسماء الكائنات باسم العنصرالذي يملك نطاق الاسم. في المثال التالي، يتم انشاء NameScope لـ myMainPanel. يتم اضافة زرارين ، button1 و button2، إلى اللوحة و ويتم تسجيل أسميهمها. يتم انشاء حركات عدة وStoryboard. تستخدم طريقة Begin الخاصة بلوحة العمل لبدء تشغيل الحركات.

لأن button1 ، button2 ، و myMainPanel تشارك جميعها في نفس اسم النطاق، يمكن استخدام أي منها مع أسلوب Storyboard Begin تشغيل الحركة.
