示例1: AddDropDownListAfterCurrentNode
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
