JSF-Ders 12 Veritabanı Veri Güncelleme-Datatable Veri Güncelleme

Eylül 21, 2017Temmuz 29, 2019 Abdullah Furkan KOÇ 2 yorum datatable listeleme, datatble, datatble güncelleme, Java Server Faces, JSF

Merhaba arkadaşlar bu yazımda size veritabanında veri güncelleme ve datatable üzerinde veri güncellemeden bir örnek ile bahsedeceğim. Öncelikli olarak jsf ‘ rendered değerinden bahsetmek istiyorum.

JSF Rendered nedir? Rendered Kullanımı?

Rendered bileşenin sitede görünüp görünmemesini ayarlayan özelliktir. Rendered değer olarak true yada false alır.Eğer true alırsa o bileşen sitede görünür, eğer false alırsa o bileşen sitede görünmez ve kullanılmaz.

Şimdi örneğe geçebiliriz:
