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. The PreviousViewCommandName and NextViewCommandName fields are used to provide automatic navigation between the previous and next View controls in the survey. If the user clicks the Retake Survey button in the last View of the survey, the SwitchViewByIndexCommandName field is used along with a command argument of 0 to redirect the user back to the first View of the survey.

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 Forms Page Code Model.

Remarks
Use the SwitchViewByIndexCommandName field to represent the "SwitchViewByIndex" command name.
You can use the value of this field to take advantage of the MultiView control's automatic updating of the active View control. For example, if a View control contains a Button control that navigates to the first View when clicked, you can set the CommandName property to the value of the SwitchViewByIndexCommandName field, which is "SwitchViewByIndex". Set the CommandArgument property to the index of the first View in the MultiView control, which is 0. This causes the MultiView control to automatically set the ActiveViewIndex property to 0 when the button is clicked.
