Provides an interface that classes implement to provide navigation user interface data and values to navigation controls.
Assembly: System.Web (in System.Web.dll)
Thetype exposes the following members.
|Description||Gets text that represents the description of a navigation node of a navigation control.|
|Name||Gets the text that represents the name of a navigation node of a navigation control.|
|NavigateUrl||Gets the URL to navigate to when the navigation node is clicked.|
|Value||Gets a non-displayed value that is used to store any additional data about the navigation node.|
The interface allows navigation controls, such as the TreeView and Menu controls, to automatically render data from a data source that represents hierarchical site navigation data. The interface is implemented by the SiteMapNode type that is returned from the SiteMapDataSource control so that navigation controls can render data automatically without a page developer explicitly defining the data binding associations to the properties of SiteMapNode. For example, the SiteMapDataSource control enables declarative data binding so that a page developer does not have to populate the TreeView.DataBindings or Menu.DataBindings properties explicitly for the TreeView and Menu controls, respectively.
The interface can also be implemented on objects that are returned by an ObjectDataSource control in order to enable automatic rendering of navigation control without explicit data binding.
