Keterangan

SeparatorStyle Gunakan properti untuk menyediakan gaya kustom untuk pemisah di antara setiap item dalam DataList kontrol. Pemisah memungkinkan Anda menempatkan elemen dengan konten kustom di antara setiap item dalam DataList kontrol. Atribut gaya umum yang dapat disesuaikan termasuk warna latar depan, warna latar belakang, font, dan perataan konten dalam sel. Menyediakan gaya yang berbeda akan meningkatkan tampilan DataList kontrol.

Untuk menentukan gaya kustom untuk pemisah, tempatkan <SeparatorStyle> tag di antara tag DataList pembuka dan penutup kontrol. Anda kemudian dapat mencantumkan atribut gaya dalam tag pembuka <SeparatorStyle> .
