Remarks
In this topic: IntroductionThe MultiView control is a container for a group of View controls. It allows you to define a group of View controls, where each View control contains child controls. Your application can then render a specific View control to the client based on criteria such as user identity, user preferences, and information passed in a query-string parameter. You can also use the MultiView control to create wizards. In this scenario, each View control contained in a MultiView control represents a different step or page in the wizard. You should also use this control to develop multiple-screen applications for mobile devices. This control provides the same functionality as the ASP.NET mobile Form control in .NET Framework version 1.1. Only one View control at a time can be defined as the active view within a MultiView control. When a View control is defined as the active view, the child controls that it contains are rendered to the client. You can use either the ActiveViewIndex property or the SetActiveView method to define the active view. If the ActiveViewIndex property is empty, the MultiView control does not render any content to the client. If the active view is set to a View that does not exist within the MultiView control, an ArgumentOutOfRangeException is raised at run time. You can define the active view declaratively or programmatically. Setting the ActiveViewIndex property declaratively when you define the MultiView control causes the View control that is set as the active view to render to the client the first time the MultiView control is called. The following code example demonstrates how to set the ActiveViewIndex property declaratively.
<asp:MultiView id="MultiView1" ActiveViewIndex=0 runat="Server">
Setting the ActiveViewIndex property programmatically, or calling the SetActiveView method, allows the application to determine which View control to render to the client at run time based on criteria such as a user's identity or preferences. To allow users to navigate between View controls within a MultiView control, you can add a LinkButton or Button control to each View control. To take advantage of the MultiView control's automatic updating of the currently active View, set the CommandName property on the button or link button to the value of one of the following command-name fields that corresponds to the desired navigation behavior: PreviousViewCommandName, NextViewCommandName, SwitchViewByIDCommandName, or SwitchViewByIndexCommandName.

Examples
The following code example demonstrates how to use a MultiView control to create a basic survey. Each View control is a separate survey question. When the user clicks the Previous button on any page, the ActiveViewIndex property is decremented to navigate to the previous View control. When the user clicks the Next button on any page, the ActiveViewIndex property is incremented to navigate to the next View control. .gif) Note |

The following code samples use the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information on the Web Forms code model, see ASP.NET Web Page Code Model. |

The following code example demonstrates how to create a basic MultiView control that contains three View controls. The view that the user selects from the list box is set to the active view and displayed to the user. For a more detailed example of the MultiView control, see the other code examples provided in this topic.

The following code example demonstrates how to create a MultiView control that contains three View controls. A View control does not have any style properties. Therefore, each View control contains a Panel control to allow styles to be set on the View control. The first time the page is loaded, the DefaultView is set as the active view using the SetActiveView method. Each View control contains link buttons to allow the user to navigate to different views.

Notes
Dans cette rubrique : IntroductionLe contrôle MultiView est un conteneur pour un groupe de contrôles View. Il vous permet de définir un groupe de contrôles View, où chaque contrôle View contient des contrôles enfants. Votre application peut rendre ensuite un contrôle View spécifique au client en fonction des critères, tels que l'identité de l'utilisateur, les préférences de l'utilisateur et les informations passées dans un paramètre de chaîne de requête. Vous pouvez également utiliser le contrôle MultiView pour créer des Assistants. Dans ce scénario, chaque contrôle View contenu dans un contrôle MultiView représente une étape ou une page différente de l'Assistant. Vous pouvez également utiliser ce contrôle pour développer des applications à plusieurs écrans pour les appareils mobiles. Ce contrôle fournit les mêmes fonctionnalités que le contrôle Form mobile ASP.NET dans la version 1.1 du .NET Framework. Un seul contrôle View à la fois peut être défini comme étant la vue active dans un contrôle MultiView. Lorsqu'un contrôle View est défini en tant que vue active, les contrôles enfants qu'il contient sont rendus au client. Vous pouvez utiliser la propriété ActiveViewIndex ou la méthode SetActiveView pour définir la vue active. Si la propriété ActiveViewIndex est vide, le contrôle MultiView ne rend pas de contenu au client. Si la vue active est attribuée à un View qui n'existe pas dans le contrôle MultiView, une ArgumentOutOfRangeException est déclenchée au moment de l'exécution. Vous pouvez définir la vue active de manière déclarative ou par programme. Si vous définissez la propriété ActiveViewIndex de manière déclarative lorsque vous définissez le contrôle MultiView, le contrôle View défini en tant que vue active affiche le client lorsque le contrôle MultiView est appelé pour la première fois. L'exemple de code suivant montre comment définir la propriété ActiveViewIndex de façon déclarative.
<asp:MultiView id="MultiView1" ActiveViewIndex=0 runat="Server">
Lorsque vous définissez la propriété ActiveViewIndex par programme, ou que vous appelez la méthode SetActiveView, l'application détermine le contrôle View à rendre au client au client au moment de l'exécution en fonction des critères, tels que l'identité ou les préférences de l'utilisateur. Pour permettre aux utilisateurs de naviguer entre les contrôles View dans un contrôle MultiView, vous pouvez ajouter un contrôle LinkButton ou Button à chaque contrôle View. Pour profiter de la mise à jour automatique du contrôle MultiView du View actuellement actif, affectez à la propriété CommandName du bouton ou bouton de liaison la valeur de l'un des champs de nom de commande suivants qui correspond au comportement de navigation souhaité : PreviousViewCommandName, NextViewCommandName, SwitchViewByIDCommandName ou SwitchViewByIndexCommandName.

Exemples
L'exemple de code suivant montre comment utiliser un contrôle MultiView pour créer une enquête de base. Chaque contrôle View est une question d'enquête distincte. Lorsque l'utilisateur clique sur le bouton Précédent d'une page, la propriété ActiveViewIndex est décrémentée pour naviguer vers le contrôle View précédent. Lorsque l'utilisateur clique sur le bouton Suivant d'une page, la propriété ActiveViewIndex est incrémentée pour naviguer vers le contrôle View suivant. | Remarque |

L'exemple de code suivant montre comment créer un contrôle MultiView de base qui contient trois contrôles View. L'affichage que l'utilisateur sélectionne dans la zone de liste est affecté à la vue active et affiché pour l'utilisateur. Pour obtenir un exemple plus détaillé du contrôle MultiView, consultez les autres exemples de code fournis dans cette rubrique.

L'exemple de code suivant montre comment créer un contrôle MultiView qui contient trois contrôles View. Un contrôle View n'a aucune propriété de style. Par conséquent, chaque contrôle View contient un contrôle Panel afin que les styles soient affectés au contrôle View. Lorsque la page est chargée pour la première fois, le DefaultView est défini comme étant la vue active à l'aide de la méthode SetActiveView. Chaque contrôle View contient des boutons de liaison pour permettre à l'utilisateur de naviguer vers différents affichages.
