Keterangan

Saat halaman diaktifkan (dengan mengatur AllowPaging properti ke true), baris tambahan yang disebut baris pager secara otomatis ditampilkan dalam DetailsView kontrol. Baris pager berisi kontrol yang memungkinkan pengguna menavigasi ke rekaman lain, dan dapat ditampilkan di bagian atas, bawah, atau bagian atas dan bawah kontrol. TopPagerRow Gunakan properti untuk mengakses DetailsViewRow objek yang mewakili baris pager atas secara terprogram dalam DetailsView kontrol.

Catatan

Properti TopPagerRow hanya tersedia setelah DetailsView kontrol membuat baris pager bawah dalam peristiwa tersebut ItemCreated .

Properti ini umumnya digunakan ketika Anda perlu memanipulasi baris pager atas secara terprogram, misalnya saat menambahkan konten kustom. Setiap modifikasi pada TopPagerRow properti harus dilakukan setelah DetailsView kontrol dirender; jika tidak, DetailsView kontrol akan menimpa perubahan apa pun.
