The ASP.NET Menu control
allows you to develop both statically and dynamically displayed menus for your ASP.NET Web pages.
You can configure the contents of the Menu control directly in the control, or you can specify the contents by binding the control to a data source.
Without writing any code, you can control the appearance, orientation, and content of an ASP.NET Menu control.
In addition to the visual properties exposed by the control, the control supports ASP.NET control skins and themes.
