Açıklamalar

Rows özelliği (koleksiyon), veri satırlarını bir DetailsView denetimde depolamak için kullanılır. Denetim, DetailsView veri kaynağındaki Rows her kayıt için bir DetailsViewRow nesne oluşturup nesneyi koleksiyona ekleyerek koleksiyonu otomatik olarak doldurur. Bu özellik genellikle denetimdeki belirli bir satıra erişmek veya satır koleksiyonunun tamamını yinelemek için kullanılır.

Not

Koleksiyonda Rows yalnızca veri satırları depolanır. DetailsViewRow Üst bilgi, alt bilgi ve disk belleği satırlarını temsil eden nesneler koleksiyona dahil değildir.
