介绍Introduction

SiteMapDataSource 控件是由为站点配置的站点地图提供程序存储的站点地图数据的数据源。The SiteMapDataSource control is a data source to the site map data that is stored by the site map providers that are configured for your site. SiteMapDataSource 使并非专门站点导航控件的 Web 服务器控件(如 TreeViewMenuDropDownList 控件)可以绑定到分层站点地图数据。The SiteMapDataSource enables Web server controls that are not specifically site navigation controls, such as the TreeView, Menu, and DropDownList controls, to bind to hierarchical site map data. 您可以使用这些 Web 服务器控件以目录形式显示网站地图,或在站点中主动导航。You can use these Web server controls to display a site map as a table of contents or to actively navigate a site. 此外,还可以使用 SiteMapPath 控件,该控件专门设计为站点导航控件,因此不需要 SiteMapDataSource 控件的实例。Alternatively, you can use the SiteMapPath control, which is designed specifically as a site navigation control and therefore does not need an instance of the SiteMapDataSource control.

指定起始节点Specifying the Starting Node

SiteMapDataSource 将绑定到站点地图数据,并基于站点地图层次结构中指定的起始节点显示其视图。The SiteMapDataSource binds to site map data and presents its view based on a specified starting node in the site map hierarchy. 默认情况下,它是层次结构的根节点,但也可以是层次结构中的任何节点。By default, it is the root node of the hierarchy but it can also be any node within the hierarchy. 起始节点由多个 SiteMapDataSource 属性的值标识,如下所示:The starting node is identified by the values of several SiteMapDataSource properties as follows:

正在启动节点Starting Node 属性值Property Values
层次结构的根节点(默认设置)。The root node of the hierarchy (the default setting). StartFromCurrentNodefalseThe StartFromCurrentNode is false.

未设置 StartingNodeUrlThe StartingNodeUrl is not set.
表示当前正在查看的页的节点。The node that represents the currently viewed page. StartFromCurrentNodetrueThe StartFromCurrentNode is true.

未设置 StartingNodeUrlThe StartingNodeUrl is not set.
层次结构的特定节点。A specific node of the hierarchy. StartFromCurrentNodefalseThe StartFromCurrentNode is false.

已设置 StartingNodeUrlThe StartingNodeUrl is set.

如果将 StartingNodeOffset 属性设置为0以外的值,则它会影响开始节点以及由 SiteMapDataSource 控件公开的站点地图数据层次结构。If the StartingNodeOffset property is set to a value other than 0, it affects the starting node and with it the site map data hierarchy that is exposed by the SiteMapDataSource control. StartingNodeOffset 的负数或正整数值标识由 StartFromCurrentNodeStartingNodeUrl 属性标识的起始节点中的站点图层次结构向上或向下的级别数,以偏移由数据源控件。The negative or positive integer value of the StartingNodeOffset identifies the number of levels up or down the site map hierarchy from the starting node that is identified by the StartFromCurrentNode and StartingNodeUrl properties to offset the starting node of the subtree that is exposed by data source control.

如果 StartingNodeOffset 属性设置为负数 -n,则由数据源控件公开的子树的开始节点是所标识的起始节点上方的祖先节点n层次结构级别。If the StartingNodeOffset property is set to a negative number -n, the starting node of the subtree that is exposed by the data source control is the ancestor node n hierarchical levels above the identified starting node. 如果值n大于层次结构树中的祖先级别数,则该子树的起始节点是站点地图层次结构的根节点。If the value n is greater than the number of ancestor levels in the hierarchical tree, the starting node of the subtree is the root node of the site map hierarchy.

如果将 StartingNodeOffset 属性设置为正数 +n,则公开的子树的开始节点是所标识的起始节点下的子节点n级别。If the StartingNodeOffset property is set to a positive number +n, the starting node of the subtree that is exposed is a child node n levels below the identified starting node. 由于在层次结构中可能存在子节点的多个分支,因此,SiteMapDataSource 会尝试直接在所标识的起始节点与表示当前请求页的节点之间的路径上解析子节点(如果可能)。Because more than one branch of child nodes might exist in the hierarchy, the SiteMapDataSource attempts to resolve a child node directly on the path between the identified starting node and the node that represents the currently requested page, if possible. 如果表示当前请求页的节点不在标识的起始节点的子树中,则忽略 StartingNodeOffset 属性的值。If the node that represents the currently requested page is not in the subtree of the identified starting node, the value of the StartingNodeOffset property is ignored. 如果表示当前请求页的节点小于标识的起始节点下的n级,则当前请求的页节点将用作开始节点。If the node that represents the currently requested page is less than n levels below the identified starting node, the currently requested page node is used as the starting node.

检索站点地图数据Retrieving Site Map Data

站点地图数据是从 SiteMapProvider 对象检索的,例如 XmlSiteMapProvider,这是 ASP.NET 的默认站点地图提供程序。Site map data is retrieved from a SiteMapProvider object, such as XmlSiteMapProvider, which is the default site map provider for ASP.NET. 您可以指定为站点配置的任何提供程序,以便向 SiteMapDataSource 提供站点地图数据,并可以通过访问 SiteMap.Providers 集合获取可用提供程序的列表。You can specify any provider that is configured for your site to provide the site map data to the SiteMapDataSource and can obtain the list of available providers by accessing the SiteMap.Providers collection.

与所有数据源控件一样,SiteMapDataSource 的每个实例都与单个 helper 对象(称为 "数据源视图")相关联。Like all data source controls, every instance of a SiteMapDataSource is associated with a single helper object, known as a data source view. 根据数据源的属性,SiteMapDataSourceView 是站点地图数据的视图,并通过调用 GetHierarchicalView 方法进行检索。The SiteMapDataSourceView is a view on the site map data, according to the properties of the data source, and is retrieved by calling the GetHierarchicalView method. SiteMapDataSourceView 维护控件绑定到 SiteMapNodeCollection 对象。The SiteMapDataSourceView maintains the SiteMapNodeCollection object that the controls bind to.

默认情况下,起始节点是层次结构的根节点,但你可以将起始节点设置为任意节点。By default, the starting node is the root node of the hierarchy, but you can set the starting node to any node. 起点可以是相对于站点地图中当前位置的节点,也可以是绝对位置。The starting point can be a node that is relative to the current position in the site map or to an absolute position. 可以通过设置 StartingNodeUrl 属性指定起始节点。You can specify the starting node by setting the StartingNodeUrl property.

SiteMapDataSource 专门用于导航数据,不支持排序、筛选、分页、缓存或数据记录操作(如更新、插入或删除)等常见数据源操作。The SiteMapDataSource is specialized for navigation data, and does not support common data source operations such as sorting, filtering, paging, caching, or data record operations such as updates, insertions or deletions.
