Keterangan
Saat halaman diaktifkan (saat AllowPaging properti diatur ke true), baris tambahan yang disebut baris pager secara otomatis ditampilkan dalam FormView kontrol. Baris pager berisi kontrol yang memungkinkan pengguna menavigasi ke rekaman lain, dan dapat ditampilkan di bagian atas, bagian bawah, atau bagian atas dan bawah kontrol.
TopPagerRow Gunakan properti untuk mengakses FormViewRow objek secara terprogram yang mewakili baris pager atas dalam FormView kontrol.
Catatan
Properti TopPagerRow hanya tersedia setelah FormView kontrol membuat baris pager atas dalam peristiwa tersebut ItemCreated .
Properti ini biasanya digunakan ketika Anda perlu memanipulasi baris pager atas secara terprogram, misalnya saat menambahkan konten kustom. Setiap modifikasi pada TopPagerRow properti harus dilakukan setelah FormView kontrol terikat ke data; jika tidak, FormView kontrol akan menimpa perubahan apa pun.
