Remarks

The SiteMapDataSource control enables ASP.NET data-bound controls, such as the TreeView and Menu controls, to bind to site map data. The SiteMapDataSourceView class is used by controls developers but it is not used by page developers nor in page code.

The SiteMapDataSource returns a SiteMapDataSourceView for a specified hierarchical path when the Select method is called. Like all hierarchical data source view objects, the SiteMapDataSourceView is not named; rather, its is identified by its unique hierarchical path.

The SiteMapDataSourceView is a wrapper class on a SiteMapNodeCollection collection. The SiteMapNodeCollection class implements the IHierarchicalEnumerable interface, which the SiteMapDataSourceView class returns from a call to Select method. Because the SiteMapDataSource and SiteMapDataSourceView work with SiteMapNode objects, the view maintains an internal SiteMapNodeCollection to contain them. The collection is initialized using the view's constructors and accessed with the Select method.

Constructors

SiteMapDataSourceView(SiteMapDataSource, String, SiteMapNode)	Initializes a new named instance of the SiteMapDataSourceView class, adding the single specified node to the internal collection of nodes.
SiteMapDataSourceView(SiteMapDataSource, String, SiteMapNodeCollection)	Initializes a new named instance of the SiteMapDataSourceView class, setting the internal collection of nodes to the specified node collection.

Properties

CanDelete	Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports the ExecuteDelete(IDictionary, IDictionary) operation. (Inherited from DataSourceView)
CanInsert	Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports the ExecuteInsert(IDictionary) operation. (Inherited from DataSourceView)
CanPage	Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports paging through the data retrieved by the ExecuteSelect(DataSourceSelectArguments) method. (Inherited from DataSourceView)
CanRetrieveTotalRowCount	Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports retrieving the total number of data rows, instead of the data. (Inherited from DataSourceView)
CanSort	Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports a sorted view on the underlying data source. (Inherited from DataSourceView)
CanUpdate	Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports the ExecuteUpdate(IDictionary, IDictionary, IDictionary) operation. (Inherited from DataSourceView)
Events	Gets a list of event-handler delegates for the data source view. (Inherited from DataSourceView)
Name	Gets the name of the data source view. (Inherited from DataSourceView)
