Keterangan

DataTextField Gunakan properti untuk menentukan nama bidang yang berisi teks yang akan ditampilkan untuk keterangan hyperlink dalam HyperLinkField objek.

Alih-alih menggunakan properti ini untuk mengikat keterangan hyperlink ke bidang, Anda bisa menggunakan Text properti untuk mengatur keterangan hyperlink ke nilai statis. Dengan opsi ini, setiap hyperlink berbagi keterangan yang sama.

Nota

DataTextField Jika properti dan Text keduanya diatur, DataTextField properti diutamakan.
