[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public class SPNavigationProvider : SiteMapProvider, 
	IEditableSiteMapProvider

Derives from the ASP.NET SiteMapProvider type.

The SPNavigationProvider class allows you to write custom controls to navigate a site. The following sample code accesses the root node for the Top Link Bar and Quick Launch. From that point, a user can navigate both node hierarchies.
