The previous example uses the default site map provider and a Web.sitemap file with the following structure.

The following code example demonstrates extends the SiteMapPath control and adds new functionality to it by overriding the InitializeItem method. The DropDownSiteMapPath control adds a DropDownList after the current node, to enable easy navigation to pages that are child nodes of the current page. This example demonstrates how to work with SiteMapNodeItem objects, including checking their SiteMapNodeItemType and calling the OnItemCreated method after the items are created.

Introduction
The SiteMapPath control is a site navigation control that reflects data provided by the SiteMap object. It provides a space-saving way to easily navigate a site and serves as a point of reference for where the currently displayed page is within a site. This type of control is commonly called a breadcrumb, or eyebrow, because it displays a hierarchical path of hyperlinked page names that provides an escape up the hierarchy of pages from the current location. SiteMapDataSource. The SiteMapPath is useful for sites that have deep hierarchical page structures, but where a TreeView or Menu might require too much space on a page.
The SiteMapPath control works directly with your Web site's site map data. If you use it on a page that is not represented in your site map, it will not be displayed. For more information about site maps, see ASP.NET Site Navigation.
Nodes
The SiteMapPath is made up of nodes. Each element in the path is called a node and is represented by a SiteMapNodeItem object. The node that anchors the path and represents the base of the hierarchical tree is called the root node. The node that represents the currently displayed page is the current node. Any other node between the current node and root node is a parent node. The following table describes the three different node types.
| Node type | Description |
|---|---|
| root | A node that anchors a hierarchical set of nodes. |
| parent | A node that has one or more child nodes, but is not the current node. |
| current | A node that represents the currently displayed page. |
Node Appearance
Each node displayed by a SiteMapPath is a HyperLink or Literal control that you can apply a template or style to. The templates and styles are applied to nodes according to two rules of precedence:
If a template is defined for a node, it overrides any style defined for the node.
Templates and styles that are specific to types of nodes override general templates and styles defined for all nodes.
The NodeStyle and NodeTemplate properties are applied to all nodes, regardless of their node type. If both these properties are defined, the NodeTemplate takes precedence.
The CurrentNodeTemplate and CurrentNodeStyle properties are applied to nodes that represent the currently displayed page. If a NodeTemplate is defined in addition to the CurrentNodeTemplate, it is ignored. If a NodeStyle is defined in addition to the CurrentNodeStyle, it is merged with the CurrentNodeStyle to create a merged style. This merged style uses all the elements of the CurrentNodeStyle, plus any additional elements of the NodeStyle that do not conflict with the CurrentNodeStyle.
The RootNodeTemplate and RootNodeStyle properties are applied to the node that represents the root of the site navigation hierarchy. If a NodeTemplate is defined in addition to the RootNodeTemplate, it is ignored. If a NodeStyle is defined in addition to the RootNodeStyle, it is merged with the RootNodeStyle to create a merged style. This merged style uses all the elements of the RootNodeStyle, plus any additional elements of the NodeStyle that did not conflict with the CurrentNodeStyle. Finally, if the currently displayed page is the root page of the site, the RootNodeTemplate and RootNodeStyle are used instead of the CurrentNodeTemplate or CurrentNodeStyle.
The SiteMapPath control uses the site map provider identified by the SiteMapProvider property as its data source for site navigation information. If no provider is specified, it uses the default provider for the site, identified in the SiteMap.Provider property. Typically, this is an instance of the default site map provider for ASP.NET, the XmlSiteMapProvider. If the SiteMapPath control is used within a site but no site map provider is configured, the control throws an HttpException exception.
Events
The SiteMapPath control also provides events that you can program against. This allows you to run a custom routine whenever an event occurs. The following table lists the events supported by the SiteMapPath control.
| Event | Description |
|---|---|
| ItemCreated | Occurs when the SiteMapPath control first creates a SiteMapNodeItem and associates it with a SiteMapNode. |
| ItemDataBound | Occurs when a SiteMapNodeItem is bound to site map data contained by the SiteMapNode. |
Customizing the SiteMapPath Control
Classes that derive from SiteMapPath override the InitializeItem method to customize the SiteMapNodeItem controls contained by the navigation control. For complete control over the way SiteMapNodeItem objects are created and added to the SiteMapPath, derived classes override the CreateControlHierarchy method.
Accessibility
For information about how to configure this control so that it generates markup that conforms to accessibility standards, see Accessibility in Visual Studio and ASP.NET and ASP.NET Controls and Accessibility.
