Remarks

The SiteMapDataSource property binds to site map data and presents its view based on a specified starting node in the site map hierarchy. By default, the starting node is the root node of the hierarchy, but you can set the starting node to any node with the StartingNodeUrl property or set the StartFromCurrentNode property to true.

The value of the StartingNodeUrl property is stored in view state.
