SiteMapHierarchicalDataSourceView Class

Note: This class is new in the .NET Framework version 2.0.

Represents a data view on a site map node or collection of nodes for a SiteMapDataSource control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public class SiteMapHierarchicalDataSourceView : HierarchicalDataSourceView
public class SiteMapHierarchicalDataSourceView extends HierarchicalDataSourceView
public class SiteMapHierarchicalDataSourceView extends HierarchicalDataSourceView

The SiteMapDataSource control can present its underlying data in both tabular and hierarchical format to Web server controls that bind to it. The SiteMapHierarchicalDataSourceView is used by controls developers, but not page developers or in page code.

Controls such as Menu or DropDownList use the SiteMapDataSource to bind to site map data and present it in list form, while controls that derive from the HierarchicalDataBoundControl class, such as TreeView, bind to sitemap data and present it in hierarchical form.

If a data-bound control calls the GetView method of the SiteMapDataSource, a SiteMapDataSourceView is created by the data source. If a control calls the HierarchicalDataBoundControlGetHierarchicalView method, a SiteMapHierarchicalDataSourceView is created. The SiteMapDataSourceView class is provided for Web server controls that derive from DataBoundControl and bind to lists and tabular data, while the SiteMapHierarchicalDataSourceView is provided for Web server controls that derive from HierarchicalDataBoundControl and bind to hierarchical data.

Like all HierarchicalDataSourceView helper objects, the SiteMapHierarchicalDataSourceView defines the operations that the data source can perform with the underlying data. Because the SiteMapHierarchicalDataSourceView class only overrides the Select method, the associated SiteMapDataSource control does not support sort expressions or insert, delete, or update operations.
