Açıklamalar

nesnesinin RowType temsil ettiği satır GridViewRow türünü belirlemek için özelliğini kullanın. Aşağıdaki tabloda, numaralandırmayı kullanan DataControlRowType farklı satır türü değerleri listelemektedir.

Satır türü	Açıklama
DataRow	Denetimde GridView bir veri satırı.
Footer	Denetimdeki GridView alt bilgi satırı.
Header	Denetimdeki GridView üst bilgi satırı.
EmptyDataRow	Denetimdeki GridView boş satır. Denetimin görüntülenecek kaydı olmadığında GridView boş satır görüntülenir.
Pager	Denetimde GridView bir çağrı satırı.
Separator	Denetimde GridView ayırıcı satır.

Bu özellik genellikle bir işlemi gerçekleştirmeden önce satırın türünü belirlemek için kullanılır.
