Mendapatkan atau mengatur nilai yang menunjukkan apakah string pemformatan yang ditentukan oleh DataFormatString properti diterapkan ke nilai bidang saat kontrol terikat data yang berisi BoundField objek berada dalam mode edit.
public:
virtual property bool ApplyFormatInEditMode { bool get(); void set(bool value); };public virtual bool ApplyFormatInEditMode { get; set; }member this.ApplyFormatInEditMode : bool with get, setPublic Overridable Property ApplyFormatInEditMode As BooleanNilai Properti
true untuk menerapkan string pemformatan ke nilai bidang dalam mode edit; jika tidak, false. Defaultnya adalah false.
Contoh
Contoh kode berikut menunjukkan cara menggunakan ApplyFormatInEditMode properti untuk menerapkan string pemformatan ke nilai bidang saat GridView kontrol dalam mode edit. Pemformatan kemudian dihapus secara terprogram sebelum nilai diperbarui di sumber data.

Keterangan
Kontrol terikat data (seperti DetailsView, , FormViewdan GridView) memiliki mode tampilan berbeda yang memungkinkan pengguna membaca, mengedit, atau menyisipkan rekaman. Secara default, string pemformatan yang ditentukan oleh DataFormatString properti diterapkan ke nilai bidang hanya ketika kontrol terikat data berada dalam mode baca-saja. Untuk menerapkan string pemformatan ke nilai yang ditampilkan saat kontrol terikat data dalam mode edit, atur ApplyFormatInEditMode properti ke true.
Nota
Objek BoundField tidak secara otomatis menghapus pemformatan saat bidang diperbarui di sumber data. Jika Anda tidak ingin pemformatan sebagai bagian dari nilai disimpan, Anda harus menghapus pemformatan secara terprogram.
