| Normal | 0 | Kontrol dan batas dalam keadaan normal. |
Contoh
Contoh kode berikut menunjukkan penggunaan PartChromeState enumerasi deklaratif dengan menggunakan kontrol kustom WebPart yang direferensikan di halaman Web ASP.NET. Agar contoh kode berjalan, Anda harus mengkompilasi kode sumber ini. Anda dapat mengkompilasinya secara eksplisit dan meletakkan rakitan yang dihasilkan di folder Bin situs Web Anda atau cache perakitan global. Atau, Anda dapat meletakkan kode sumber di folder App_Code situs Anda, di mana kode tersebut akan dikompilasi secara dinamis pada durasi. Untuk panduan yang menunjukkan kedua metode kompilasi, lihat Panduan: Mengembangkan dan Menggunakan Kontrol Server Web Kustom.
Bagian pertama dari contoh berisi kode untuk kontrol kustom, bernama TextDisplayWebPart. Karena kontrol berasal dari WebPart, kontrol juga mewarisi properti umum yang Part disediakan kelas, termasuk ChromeState properti , yang menggunakan PartChromeState enumerasi sebagai jenis pengembaliannya.
