Exempel
Följande kodexempel visar hur du använder en MultiView kontroll för att skapa en grundläggande undersökning. Varje View kontroll är en separat undersökningsfråga. Fälten PreviousViewCommandName och NextViewCommandName används för att tillhandahålla automatisk navigering mellan föregående och nästa View kontroller i undersökningen. Om användaren klickar på knappen Omtagningsundersökning i den sista View undersökningen SwitchViewByIDCommandName används fältet tillsammans med kommandoargumentet "Page1" för att omdirigera användaren tillbaka till den första View i undersökningen.
Note
Följande kodexempel använder kodmodellen med en fil och kanske inte fungerar korrekt om den kopieras direkt till en kod bakom-fil. Det här kodexemplet måste kopieras till en tom textfil som har ett .aspx-tillägg. Mer information om kodmodellen Web Forms finns i ASP.NET Web Forms Page Code Model.

Kommentarer
Använd fältet SwitchViewByIDCommandName för att representera kommandonamnet "SwitchViewByID".
Du kan använda värdet för det här fältet för att dra nytta av MultiView kontrollens automatiska uppdatering av den aktiva View kontrollen. Om en View kontroll till exempel innehåller en Button kontroll som navigerar till den första View när du klickar kan du ange CommandName egenskapen till värdet för SwitchViewByIDCommandName fältet, som är "SwitchViewByID". CommandArgument Ange egenskapen till ID för den första View i MultiView kontrollen, till exempel "Sida1". Detta gör MultiView att kontrollen automatiskt anger "Page1" som aktiv View när knappen klickas.
