Keterangan

Properti Header mendapatkan referensi ke HtmlHead objek yang bisa Anda gunakan untuk mengatur informasi header dokumen untuk halaman tersebut. HtmlHead memungkinkan Anda menambahkan informasi seperti lembar gaya, aturan gaya, judul, dan metadata ke head elemen.

Catatan

Menambahkan gaya secara terprogram menggunakan metode IStyleSheet antarmuka selama postback asinkron tidak didukung. Saat Anda menambahkan kapabilitas AJAX ke halaman Web, postback asinkron memperbarui wilayah halaman tanpa memperbarui seluruh halaman. Untuk informasi selengkapnya, lihat Gambaran Umum Microsoft Ajax.
