Property Value

An SiteMapProvider that is the top-level site map provider in the provider hierarchy that the current provider belongs to.

Exception typeCondition

ProviderException

There is a circular reference to the current site map provider.

All classes that implement the SiteMapProvider class can support the concept of a site map provider hierarchy. Any hierarchical relationships between providers are maintained outside the scope of a SiteMapProviderCollection collection by the providers themselves. For an example of a functional provider hierarchy, see XmlSiteMapProvider.

The following code example demonstrates how to implement the RootProvider property in a class that implements the abstract SiteMapProvider class. The SimpleTextSiteMapProvider uses simple logic to determine whether the current provider is part of a provider hierarchy. If the provider is part of a hierarchy, it uses the RootProvider property for the parent provider as its own. If the provider is not part of a hierarchy, the provider is its own root provider.

This code example is part of a larger example provided for the SiteMapProvider class.
