Contoh
Contoh kode berikut menunjukkan penggunaan HelpVerb properti pada WebPartZone kontrol.
Agar contoh kode berfungsi, selain kode berikut, Anda memerlukan kontrol kustom WebPart . Anda dapat menggunakan kontrol Anda sendiri, atau menggunakan kode untuk kontrol kustom TextDisplayWebPart yang ditemukan di bagian Contoh dari WebPart gambaran umum kelas.
Contoh kode ini mencakup kontrol pengguna untuk memungkinkan Anda mengubah mode tampilan pada halaman Web. Untuk informasi selengkapnya tentang mode tampilan dan kode sumber dalam kontrol ini, lihat Panduan: Mengubah Mode Tampilan pada Halaman Bagian Web.

Contoh kode ini juga menyertakan halaman HTML yang dapat berisi konten Bantuan untuk TextDisplayWebPart kontrol. Agar contoh ini berfungsi, Anda harus menyimpan kode berikut dalam file bernama Textwebparthelp.htm dan menempatkannya di direktori situs yang sama dengan halaman .aspx yang menghosting TextDisplayWebPart kontrol.
<html>
<head runat="server">
<title>Text Content WebPart Help</title>
</head>
<body>
<div>

Bagian lain dari contoh kode adalah halaman .aspx yang menghosting TextDisplayWebPart kontrol dan menunjukkan penggunaan HelpVerb properti . Perhatikan bahwa di dekat bagian atas halaman, <@ Register %> deklarasi digunakan untuk mereferensikan kontrol yang dikompilasi TextDisplayWebPart , yang harus ditempatkan dalam subfolder bernama Bin.

Perhatikan juga bahwa HelpVerb properti digunakan secara deklaratif pada <asp:WebPartZone> elemen untuk mengatur teks untuk kata kerja, seperti yang ditunjukkan dalam contoh kode berikut.
<asp:WebPartZone ID="WebPartZone1" Runat="server">
<CloseVerb Text="Close WebPart" />
<HelpVerb Text="View Help" />
<ExportVerb Text="Export WebPart Definition" />
<DeleteVerb Text ="Delete WebPart" />
<MinimizeVerb Description="Minimize the control" />
<RestoreVerb Description="Restore the control" />
<ZoneTemplate>
</ZoneTemplate>
</asp:WebPartZone>
<asp:WebPartZone ID="WebPartZone1" Runat="server">
<CloseVerb Text="Close WebPart" />
<HelpVerb Text="View Help" />
<ExportVerb Text="Export WebPart Definition" />
<DeleteVerb Text ="Delete WebPart" />
<MinimizeVerb Description="Minimize the control" />
<RestoreVerb Description="Restore the control" />
<ZoneTemplate>
</ZoneTemplate>
</asp:WebPartZone>
Terakhir, perhatikan dalam contoh kode berikut bahwa HelpUrl properti diatur pada <aspSample:TextDisplayPart> elemen untuk memberikan URL ke file Bantuan.
<asp:CatalogZone ID="CatalogZone1" Runat="server">
<ZoneTemplate>
<asp:DeclarativeCatalogPart ID="DeclarativeCatalogPart1"
Runat="server">

</WebPartsTemplate>
</asp:DeclarativeCatalogPart>
<asp:PageCatalogPart ID="PageCatalogPart1" Runat="server" />

</asp:CatalogZone>
Setelah Anda memuat halaman di browser, klik item menu Mode Katalog di kontrol daftar drop-down Mode Tampilan untuk mengalihkan halaman ke mode tampilan katalog. TextDisplayWebPart Tambahkan kontrol ke halaman, tutup katalog, dan kembalikan halaman ke mode telusuri normal. Jika Anda mengklik menu drop-down kata kerja di bilah TextDisplayWebPart judul kontrol, Anda dapat mengakses kata kerja bantuan untuk membuka halaman Bantuan.
Keterangan
HelpVerb Properti dapat diakses baik secara deklaratif maupun terprogram. Anda dapat mengaksesnya secara deklaratif dalam zona dengan menggunakan <asp:HelpVerb> elemen untuk mengatur teks, deskripsi, apakah kata kerja diaktifkan, dan atribut lainnya. Namun, tidak perlu mendeklarasikan kata kerja bantuan untuk zona, karena diaktifkan secara default. Satu-satunya langkah yang diperlukan untuk mengaktifkan kata kerja bantuan agar muncul pada menu WebPart kata kerja kontrol di zona pada durasi adalah menetapkan nilai ke HelpUrl properti untuk kontrol individual WebPart .
