SiteMapNodeItemType Enumeration

 

The SiteMapNodeItemType enumeration is used by the SiteMapPath control to identify the type of a SiteMapNodeItem node within a node hierarchy.

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

Public Enumeration SiteMapNodeItemType

Member nameDescription
Current

The currently viewed page in the site navigation path.

Parent

A parent node of the currently viewed page in the site navigation path. A parent node is any node that is found between the root node and the current node in the navigation hierarchy.

PathSeparator

A site map navigation path separator. The default separator for the SiteMapPath control is the ">" character.

Root

The top node of the site navigation hierarchy. There can be only one root node.

The SiteMapPath control manages its site navigation information as a collection of SiteMapNodeItem objects. SiteMapNodeItem objects represent functionally different types of SiteMapNode nodes. Accordingly, they are managed by the SiteMapPath control. The following list describes the types of nodes available:

  • One node that represent the currently viewed page.

  • One node that is the top node of the site navigation hierarchy.

  • Zero or more nodes between the top node and the current node (parent nodes).

  • Zero or more nodes that represent site navigation path separators.

Each node is data-bound to an underlying SiteMapNode, except nodes of the PathSeparator type.

The following code example demonstrates how to call the OnItemCreated method after creating a SiteMapNodeItem within the InitializeItem method. This code example is part of a larger code example provided for the SiteMapPath class.

Private Sub AddDropDownListAfterCurrentNode(item As SiteMapNodeItem)

   Dim childNodes As SiteMapNodeCollection = item.SiteMapNode.ChildNodes

   ' Only do this work if there are child nodes.
   If Not (childNodes Is Nothing) Then

      ' Add another PathSeparator after the CurrentNode.
      Dim finalSeparator As New SiteMapNodeItem(item.ItemIndex, SiteMapNodeItemType.PathSeparator)

      Dim eventArgs As New SiteMapNodeItemEventArgs(finalSeparator)

      InitializeItem(finalSeparator)
      ' Call OnItemCreated every time a SiteMapNodeItem is
      ' created and initialized.
      OnItemCreated(eventArgs)

      ' The pathSeparator does not bind to any SiteMapNode, so
      ' do not call DataBind on the SiteMapNodeItem.
      item.Controls.Add(finalSeparator)

      ' Create a DropDownList and populate it with the children of the
      ' CurrentNode. There are no styles or templates that are applied
      ' to the DropDownList control. If OnSelectedIndexChanged is raised,
      ' the event handler redirects to the page selected.
      ' The CurrentNode has child nodes.
      Dim ddList As New DropDownList()
      ddList.AutoPostBack = True

      AddHandler ddList.SelectedIndexChanged, AddressOf Me.DropDownNavPathEventHandler

      ' Add a ListItem to the DropDownList for every node in the
      ' SiteMapNodes collection.
      Dim node As SiteMapNode
      For Each node In  childNodes
         ddList.Items.Add(New ListItem(node.Title, node.Url))
      Next node

      item.Controls.Add(ddList)
   End If
End Sub 'AddDropDownListAfterCurrentNode
