Assembly: System.Web (in System.Web.dll)
The property presumes that the SiteMapProvider object implements its internal collections such that when a parent node retrieves its ChildNodes property, the nodes are in the same order as they appear in the site map. If you use .NET Framework collection classes in an implementation of a site map provider, choose collections that implement the IList interface, such as the ArrayList or ListDictionary classes. If you choose collections that do not implement the IList interface, such as the Hashtable class, unexpected results can occur for simple site navigation operations.
