MultiView.SwitchViewByIndexCommandName Champ

Définition

Représente le nom de commande associé à la modification du contrôle View actif dans un contrôle MultiView en fonction d'un index View spécifié. Ce champ est en lecture seule.

public: static initonly System::String ^ SwitchViewByIndexCommandName;
public static readonly string SwitchViewByIndexCommandName;
 staticval mutable SwitchViewByIndexCommandName : string
Public Shared ReadOnly SwitchViewByIndexCommandName As String 

Valeur de champ

Exemples

L’exemple de code suivant montre comment utiliser un MultiView contrôle pour créer une enquête de base. Chaque View contrôle est une question d’enquête distincte. Les PreviousViewCommandName champs et NextViewCommandName sont utilisés pour fournir une navigation automatique entre les contrôles précédents et suivants View de l’enquête. Si l’utilisateur clique sur le bouton Reprendre l’enquête dans le dernier View de l’enquête, le SwitchViewByIndexCommandName champ est utilisé avec un argument de commande de 0 pour rediriger l’utilisateur vers le premier View de l’enquête.

Remarques

Utilisez le SwitchViewByIndexCommandName champ pour représenter le nom de la commande « SwitchViewByIndex ».

Vous pouvez utiliser la valeur de ce champ pour tirer parti de la MultiView mise à jour automatique du contrôle actif View . Par exemple, si un View contrôle contient un Button contrôle qui accède au premier View lorsqu’on clique dessus, vous pouvez définir la CommandName propriété sur la valeur du SwitchViewByIndexCommandName champ, qui est « SwitchViewByIndex ». Définissez la CommandArgument propriété sur l’index du premier View dans le MultiView contrôle, qui est 0. Ainsi, le MultiView contrôle définit automatiquement la ActiveViewIndex propriété sur 0 lorsque l’utilisateur clique sur le bouton.
