Açıklamalar
Denetimin disk belleği bölümü DataGrid için özel bir stil sağlamak için bu özelliği kullanın. Ayarlanabilen yaygın stil öznitelikleri arasında hücre içinde ön renk, geri renk, yazı tipi ve içerik hizalaması bulunur. Farklı bir stil sağlamak denetimin DataGrid görünümünü geliştirir.
Disk belleği bölümü için özel bir stil belirtmek için, etiketleri denetimin <PagerStyle>
açma ve kapatma etiketleri DataGrid arasına yerleştirin. Ardından, stil özniteliklerini açılış <PagerStyle>
etiketi içinde listeleyebilirsiniz.
