public virtual SiteMapNode RootNode { get; }

Property Value

Type: System.Web.SiteMapNode
A SiteMapNode that represents the root node of the site navigation structure.

ExceptionCondition
InvalidOperationException

The root node cannot be retrieved from the root provider.

The SiteMapNode class relies on the site map provider with which it is associated to track its relationships to other nodes in the site map. The RootNode property calls the RootNode property of the root provider (the RootProvider property) to retrieve the root node.
