The current XmlSiteMapProvider is not the provider associated with node.


A node with the same URL or key is already registered with the XmlSiteMapProvider. - or -

A duplicate site map node has been encountered programmatically, such as when linking two site map providers.

- or -

node is the root node of the XmlSiteMapProvider.

The node parameter is added to an internal collection, and a parent/child relationship is created between it and parentNode.

The XmlSiteMapProvider class, derived from the StaticSiteMapProvider class and the default site map provider for ASP.NET, uses the Url property of a SiteMapNode object as a lookup key in its internal collections, by default. If the Url property of the SiteMapNode is set, it must be unique within the scope of the provider. The FindSiteMapNode method attempts to retrieve nodes based on their Url. Otherwise, you can use the Key property, and the corresponding FindSiteMapNodeFromKey method, to retrieve nodes.
