SiteMapNodeItem Constructor (Int32, SiteMapNodeItemType)
Initializes a new instance of the SiteMapNodeItem class, using the specified index and SiteMapNodeItemType.
Assembly: System.Web (in System.Web.dll)
Parameters
- itemIndex
-
Type:
System.Int32
The index in the Controls collection that the SiteMapPath control uses to track the SiteMapNodeItem object.
- itemType
-
Type:
System.Web.UI.WebControls.SiteMapNodeItemType
The functional type of SiteMapNode that this SiteMapNodeItem represents.
If the PathDirection is RootToCurrent, you can add each deeper-level item of the site navigation hierarchy at the end of the Controls collection. However, if the PathDirection property is set to CurrentToRoot, each deeper-level node must be inserted at the beginning of the Controls collection.
The following code example demonstrates how to create a SiteMapNodeItem object. 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
