Public Property WebPartsListUserControlPath As String
Nilai Properti
String dengan jalur ke kontrol pengguna yang berisi sekumpulan WebPart kontrol server atau .
- Atribut
Contoh
Contoh kode berikut menunjukkan cara menggunakan WebPartsListUserControlPath properti secara deklaratif dan terprogram. Contoh ini memiliki lima bagian:
Kontrol pengguna yang memungkinkan Anda mengubah mode tampilan pada halaman Bagian Web.
File kode sumber yang berisi dua kontrol kustom WebPart .
Kontrol pengguna lain yang berisi referensi ke kontrol kustom WebPart , dan dirujuk oleh WebPartsListUserControlPath properti pada halaman Web.
Halaman Web yang berisi CatalogZone kontrol dan DeclarativeCatalogPart kontrol yang mereferensikan kontrol pengguna yang berisi kontrol kustom.
Penjelasan tentang cara kerja contoh saat Anda memuat halaman di browser.
Bagian pertama dari contoh kode ini adalah kontrol pengguna yang memungkinkan pengguna mengubah mode tampilan pada halaman Web. Untuk detail tentang mode tampilan dan deskripsi kode sumber dalam kontrol ini, lihat Panduan: Mengubah Mode Tampilan pada Halaman Bagian Web.

Bagian kedua dari contoh kode adalah kode sumber untuk dua kontrol kustom WebPart . 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.

Saat Anda memuat halaman di browser, pilih Mode Katalog di kontrol daftar drop-down Mode Tampilan untuk beralih ke mode katalog. Dalam mode katalog, Anda dapat melihat kontrol yang tersedia untuk ditambahkan ke halaman. Klik tombol Perbarui properti Perbarui WebPartsListUserControlPath , tanpa memasukkan nilai dalam kotak teks. Perhatikan bahwa dengan string kosong ("") yang ditetapkan ke properti , katalog diperbarui dan hanya kontrol yang secara eksplisit dideklarasikan di halaman tetap berada dalam katalog.

Keterangan
Properti WebPartsListUserControlPath memungkinkan pengembang untuk menentukan jalur ke kontrol pengguna yang berisi sekumpulan WebPart atau kontrol server lain yang dapat ditambahkan ke WebPartZoneBase zona. Jika jalur yang valid ke kontrol pengguna ditetapkan ke properti ini, kontrol secara otomatis ditambahkan ke katalog pada waktu kompilasi.
Properti WebPartsListUserControlPath dapat berguna karena menyediakan cara untuk mengemas dan menggunakan kembali sekumpulan kontrol yang tersedia di banyak halaman atau situs yang berbeda. Daripada mendeklarasikan setiap kontrol secara manual dalam katalog untuk setiap halaman yang ingin menyediakan katalog, pengembang dapat menggunakan properti ini untuk menunjuk ke kontrol pengguna yang mereferensikan seluruh set WebPart kontrol. Selain itu WebPartsListUserControlPath , properti dapat digunakan bersama dengan WebPart kontrol yang secara eksplisit dideklarasikan dalam <asp:declarativecatalogpart>
elemen pada halaman Web.
