Keterangan

Row Gunakan properti untuk mengakses FormViewRow objek yang mewakili baris data secara terprogram. Baris data berisi konten yang berbeda berdasarkan templat yang dirender untuk mode saat ini (ditentukan oleh CurrentMode properti ). Anda hanya dapat mengakses konten templat untuk mode saat ini. Tabel berikut ini memperlihatkan templat mana yang digunakan untuk setiap mode.

Catatan

Properti Row hanya tersedia setelah FormView kontrol membuat baris data dalam peristiwa tersebut ItemCreated .

Properti ini umumnya digunakan ketika Anda perlu memanipulasi baris data secara terprogram, misalnya saat menambahkan konten kustom. Setiap modifikasi pada Row properti harus dilakukan setelah FormView kontrol terikat data; jika tidak, FormView kontrol akan menimpa perubahan apa pun.
