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, bawah, atau bagian atas dan bawah kontrol. BottomPagerRow Gunakan properti untuk mengakses FormViewRow objek yang mewakili baris pager bawah secara terprogram dalam FormView kontrol.

Catatan

Properti BottomPagerRow hanya tersedia setelah FormView kontrol membuat baris pager bawah dalam peristiwa tersebut ItemCreated .

Properti ini biasanya digunakan ketika Anda perlu memanipulasi baris pager bawah secara terprogram, misalnya saat menambahkan konten kustom. Setiap modifikasi pada BottomPagerRow properti harus dilakukan setelah FormViewRow objek yang mewakili baris pager bawah telah dibuat; jika tidak, FormView kontrol akan menimpa perubahan apa pun.
