The 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 that is passed in a query-string parameter. You can also use the MultiView control to create wizards. In this scenario, each View control that is 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 Microsoft .NET Framework version 1.1.

For more information on using the MultiView and View controls, see MultiView and View Web Server Controls.

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.
