Keterangan

Untuk menerapkan gaya poin ke paragraf teks, atur SelectionBullet properti ke true lalu atur BulletIndent properti ke jumlah piksel yang harus diindentasi teks. Paragraf akan menerapkan gaya poin dengan jumlah indentasi yang ditentukan setelah poin. Properti ini hanya mempengaruhi paragraf saat ini dalam teks kontrol dan poin yang saat ini dipilih dalam daftar item berpoin. Untuk menerapkan tingkat indentasi yang berbeda ke seluruh daftar item berpoin, semua teks item berpoin harus dipilih sebelum mengatur BulletIndent properti.
