Keterangan
Gunakan properti ini untuk menentukan bagaimana browser mengirim data formulir ke server untuk diproses. Dua metode umum yang didukung oleh semua browser adalah GET dan POST.
Perhatian
Anda dapat mengambil alih nilai default properti ini dan menggunakan GET metode alih-alih POST. Namun, karena GET permintaan terbatas dalam berapa banyak data yang dapat mereka sertakan, menggunakan GET metode dapat, dalam beberapa kasus, menyebabkan kemampuan postback dan manajemen status yang disediakan oleh kerangka kerja halaman ASP.NET gagal.
