Contoh
Contoh ini menunjukkan cara menggunakan Style objek untuk mengubah properti gaya beberapa kontrol sekaligus. Setiap kali salah Style satu nilai properti berubah, setiap kontrol harus memanggil metodenya ApplyStyle . Perhatikan bahwa tidak semua kontrol yang disertakan mendukung semua properti yang ditunjukkan. Jika kontrol tidak mendukung properti tertentu, tampilan kontrol tidak akan berubah saat nilai properti diubah.
