Exemples
L’exemple de code suivant illustre l’utilisation de la HelpVerb propriété sur un WebPartZone contrôle .
Pour que l’exemple de code fonctionne, en plus du code suivant, vous avez besoin d’un contrôle personnalisé WebPart . Vous pouvez utiliser votre propre contrôle ou utiliser le code du contrôle personnalisé TextDisplayWebPart figurant dans la section Exemple de la vue d’ensemble de la WebPart classe.
Cet exemple de code inclut un contrôle utilisateur pour vous permettre de modifier les modes d’affichage sur une page Web. Pour plus d’informations sur les modes d’affichage et le code source dans ce contrôle, consultez Procédure pas à pas : modification des modes d’affichage sur une page de composants WebPart.

Cet exemple de code inclut également une page HTML qui peut contenir du contenu d’aide pour le TextDisplayWebPart contrôle. Pour que cet exemple fonctionne, vous devez enregistrer le code suivant dans un fichier nommé Textwebparthelp.htm et le placer dans le même répertoire de votre site que la page .aspx qui héberge le TextDisplayWebPart contrôle.
<html>
<head runat="server">
<title>Text Content WebPart Help</title>
</head>
<body>
<div>
<h1>Text Content WebPart Help</h1>
To make the WebPart control work...
</div>
</body>

Notez également que la HelpVerb propriété est utilisée de manière déclarative sur l’élément <asp:WebPartZone> pour définir le texte du verbe, comme illustré dans l’exemple de code suivant.
<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>
Enfin, notez dans l’exemple de code suivant que la HelpUrl propriété est définie sur l’élément <aspSample:TextDisplayPart> pour fournir l’URL du fichier d’aide.
<asp:CatalogZone ID="CatalogZone1" Runat="server">
<ZoneTemplate>
<asp:DeclarativeCatalogPart ID="DeclarativeCatalogPart1"
Runat="server">
<WebPartsTemplate>
<aspSample:TextDisplayWebPart
runat="server"
id="textwebpart"
title = "Text Content WebPart"
width="350px"
AllowClose="true"
ExportMode="All"
HelpMode="Modal"
HelpUrl="TextWebPartHelp.htm" />
</WebPartsTemplate>
</asp:DeclarativeCatalogPart>
<asp:PageCatalogPart ID="PageCatalogPart1" Runat="server" />
</ZoneTemplate>
</asp:CatalogZone>
<asp:CatalogZone ID="CatalogZone1" Runat="server">
<ZoneTemplate>
<asp:DeclarativeCatalogPart ID="DeclarativeCatalogPart1"
Runat="server">
<WebPartsTemplate>
<aspSample:TextDisplayWebPart
runat="server"
id="textwebpart"
title = "Text Content WebPart"
width="350px"
AllowClose="true"
ExportMode="All"
HelpMode="Modal"
HelpUrl="TextWebPartHelp.htm" />
</WebPartsTemplate>
</asp:DeclarativeCatalogPart>
<asp:PageCatalogPart ID="PageCatalogPart1" Runat="server" />
</ZoneTemplate>
</asp:CatalogZone>
Après avoir chargé la page dans un navigateur, cliquez sur l’élément de menu Mode catalogue dans le contrôle de liste déroulante Mode d’affichage pour basculer la page en mode d’affichage catalogue. Ajoutez le TextDisplayWebPart contrôle à la page, fermez le catalogue et retournez la page en mode de navigation normal. Si vous cliquez sur le menu déroulant des verbes dans la barre de titre du TextDisplayWebPart contrôle, vous pouvez accéder au verbe d’aide pour ouvrir la page d’aide.
Remarques
La HelpVerb propriété est accessible de manière déclarative ou programmatique. Vous pouvez y accéder de manière déclarative dans une zone en utilisant l’élément <asp:HelpVerb> pour définir le texte, la description, si le verbe est activé et d’autres attributs. Toutefois, il n’est pas nécessaire de déclarer un verbe d’aide pour une zone, car il est activé par défaut. La seule étape nécessaire pour permettre à un verbe d’aide d’apparaître dans le menu verbes des contrôles dans WebPart une zone au moment de l’exécution consiste à affecter une valeur à la HelpUrl propriété pour des contrôles individuels WebPart .
