SiteMapNode Constructor (SiteMapProvider, String)
Initializes a new instance of the SiteMapNode class, using the specified key to identify the page that the node represents and the site map provider that manages the node.
Assembly: System.Web (in System.Web.dll)
The XmlSiteMapProvider class, which is the default SiteMapProvider provider implementation for ASP.NET, uses the SiteMapNode.Url property as a lookup key, if one is provided for the node (if a URL is not provided, a tracking identifier is generated for the node). Therefore, any SiteMapNode control that provides a URL and is used by the XmlSiteMapProvider must have a unique URL within the scope of the provider.
