Açıklamalar

Denetimin FooterRow alt bilgi satırını GridView temsil eden nesneye GridViewRow program aracılığıyla erişmek için özelliğini kullanın.

Not

FooterRow özelliği yalnızca denetim olayda GridView alt bilgi satırını oluşturduğunda RowCreated kullanılabilir.

Bu özellik, örneğin özel içerik eklerken alt bilgi satırını program aracılığıyla işlemeniz gerektiğinde yaygın olarak kullanılır. Özellikte FooterRow yapılan tüm değişiklikler, denetim işlendikten GridView sonra gerçekleştirilmelidir; aksi takdirde, GridView denetim tüm değişikliklerin üzerine yazar.

Şunlara uygulanır
