Public Overridable ReadOnly Property ItemIndex As Integer

Property Value

Type: System.Int32

An integer that represents the location of the SiteMapNodeItem in the SiteMapPath control's internal collections.

The following code example demonstrates how to get the ItemIndex property and use it to create a SiteMapNodeItem path separator. PathSeparator node items are created at the same index as the previous node. This code example is part of a larger 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
