Represents a data view on a site map node or collection of nodes for a SiteMapDataSource control.
Assembly: System.Web (in System.Web.dll)
Thetype exposes the following members.
|SiteMapHierarchicalDataSourceView(SiteMapNode)||Initializes a new instance of the class, adding the specified node to the IHierarchicalEnumerable collection that the data source view maintains.|
|SiteMapHierarchicalDataSourceView(SiteMapNodeCollection)||Initializes a new instance of the class, setting the specified collection to the IHierarchicalEnumerable collection that the data source view maintains.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|Select||Gets the collection of the SiteMapNode objects that represents the site navigation structure for the current user. (Overrides HierarchicalDataSourceView.Select().)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The SiteMapDataSource control can present its underlying data in both tabular and hierarchical format to Web server controls that bind to it. The 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 HierarchicalDataBoundControl GetHierarchicalView method, a is created. The SiteMapDataSourceView class is provided for Web server controls that derive from DataBoundControl and bind to lists and tabular data, while the is provided for Web server controls that derive from HierarchicalDataBoundControl and bind to hierarchical data.
Like all HierarchicalDataSourceView helper objects, the defines the operations that the data source can perform with the underlying data. Because the class only overrides the Select method, the associated SiteMapDataSource control does not support sort expressions or insert, delete, or update operations.
