Animatsiyani boshlash uchun elementning usuli deyiladi BeginAnimation(). Bu usul animatsiya
qilinadigan bog'liqlik xususiyati va animatsiya ob'ektining o'ziga o'tadi.
Bunday holda, tugmaning kengligi joriy qiymatdan 150 pikselgacha o'zgaradi. Va bu o'zgarish 3
soniya davom etadi.
Agar animatsiya takrorlanishini istasak, RepeatBehavior xususiyatidan foydalanishimiz mumkin:
Bunday holda, animatsiya ikki marta takrorlanadi. Biz takrorlash vaqtini ham belgilashimiz
mumkin:
Bu erda takrorlash vaqti 7 soniya. Animatsiya 3 soniya davom etadi, ya'ni 7/3 takrorlash bo'ladi:
ikkita to'liq takrorlash va ikkinchi holatda kenglik faqat kerakli kenglikning uchdan bir qismiga
oshadi.
Xususiyatning teskari yo'nalishda silliq o'zgarishini o'rnatish uchun AutoReverse xususiyatini
qo'llang:
Tugallangan tadbir
Animatsiya tugagach, tugallangan hodisa yaratiladi, biz uni boshqarishimiz mumkin:
