Keterangan
Properti Rows (koleksi) digunakan untuk menyimpan baris data dalam DetailsView kontrol. DetailsView Kontrol secara otomatis mengisi Rows koleksi dengan membuat DetailsViewRow objek untuk setiap rekaman di sumber data lalu menambahkan objek ke koleksi. Properti ini biasanya digunakan untuk mengakses baris tertentu dalam kontrol atau untuk melakukan iterasi melalui seluruh kumpulan baris.
Nota
Hanya baris data yang disimpan dalam Rows koleksi. Objek DetailsViewRow yang mewakili baris header, footer, dan pager tidak disertakan dalam koleksi.
