MultiView.Views Property

Note: This property is new in the .NET Framework version 2.0.

Gets the collection of View controls in the MultiView control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public virtual ViewCollection Views { get; }
/** @property */
public ViewCollection get_Views ()

public function get Views () : ViewCollection

Property Value

A ViewCollection that represents a collection of View controls within a MultiView control. The default is a null reference (Nothing in Visual Basic).

Use this property to programmatically manage the View controls in a MultiView control.

The following example demonstrates how to programmatically add View controls to a MultiView control. After each View control is created, the MultiView.Views.Add() syntax is used to add the View control to the ViewCollection collection of the MultiView control.

NoteNote

The following code sample uses 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.
