Menu.Menu Constructor

Initializes a new instance of the Menu class.

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

public Menu ()
public Menu ()
public function Menu ()
Not applicable.

Use this constructor to create and initialize a new instance of the Menu class. To dynamically add a Menu control to a page, create a new Menu object, set its properties, and then add it to the Controls collection of a container control, such as PlaceHolder.

The following code example demonstrates how to use the constructor to dynamically add a Menu control to a page.
