Gets a SiteMapNode control that represents the currently requested page.
(in System.Web.dll)
Visual Basic (Declaration)
Public Shared ReadOnly Property CurrentNode As SiteMapNode
Dim value As SiteMapNode
value = SiteMap.CurrentNode
public static SiteMapNode CurrentNode { get; }
public:
static property SiteMapNode^ CurrentNode {
SiteMapNode^ get ();
}
public static function get CurrentNode () : SiteMapNode
Property Value
Type:
System.Web..::.SiteMapNodeA SiteMapNode instance that represents the currently requested page; otherwise, nullNothingnullptra null reference (Nothing in Visual Basic), if no representative node exists in the site map information.
The SiteMap class retrieves the CurrentNode property by requesting it from the provider.
If no representative node exists for the page in the site map information, or if security trimming is enabled and the node cannot be returned for the current user, nullNothingnullptra null reference (Nothing in Visual Basic) is returned.
The SiteMapResolve event is raised by the default site map provider if one or more subscriptions exist.
If you implement your own SiteMapProvider object, you might create your own mechanism to find and retrieve the CurrentNode. However, if you extend the StaticSiteMapProvider class and use a URL-based scheme to identify pages, you can override the FindSiteMapNode method.
The following code example demonstrates how to use the CurrentNode property to retrieve the SiteMapNode object that represents the current page.
<script runat="server">
Private Sub Page_Load(sender As Object, e As EventArgs)
' Examine the CurrentNode, and navigate the SiteMap relative to it.
Response.Write(SiteMap.CurrentNode.Title & "<br />")
Response.Write("<font COLOR='red'>" & SiteMap.CurrentNode.Url & "</font><br />")
' What nodes are children of the CurrentNode?
If (SiteMap.CurrentNode.HasChildNodes) Then
Dim ChildNodesEnumerator As IEnumerator = SiteMap.CurrentNode.ChildNodes.GetEnumerator()
While (ChildNodesEnumerator.MoveNext())
' Prints the Title of each node.
Response.Write(ChildNodesEnumerator.Current.ToString() & "<br />")
End While
End If
Response.Write("<hr />")
' Examine the RootNode, and navigate the SiteMap relative to it.
Response.Write(SiteMap.RootNode.Title & "<br />")
Response.Write(SiteMap.RootNode.Url & "<br />")
' What nodes are children of the RootNode?
If (SiteMap.RootNode.HasChildNodes) Then
Dim RootNodesChildrenEnumerator As IEnumerator = SiteMap.RootNode.ChildNodes.GetEnumerator()
While (RootNodesChildrenEnumerator.MoveNext())
' Prints the Title of each node.
Response.Write(RootNodesChildrenEnumerator.Current.ToString() & "<br />")
End While
End If
End Sub ' Page_Load
</script>
<script runat="server">
private void Page_Load(object sender, System.EventArgs e)
{
// Examine the CurrentNode, and navigate the SiteMap relative to it.
Response.Write(SiteMap.CurrentNode.Title + "<br />");
Response.Write("<font COLOR='red'>" + SiteMap.CurrentNode.Url + "</font><br />");
// What nodes are children of the CurrentNode?
if (SiteMap.CurrentNode.HasChildNodes) {
IEnumerator childNodesEnumerator = SiteMap.CurrentNode.ChildNodes.GetEnumerator();
while (childNodesEnumerator.MoveNext()) {
// Prints the Title of each node.
Response.Write(childNodesEnumerator.Current.ToString() + "<br />");
}
}
Response.Write("<hr />");
// Examine the RootNode, and navigate the SiteMap relative to it.
Response.Write(SiteMap.RootNode.Title + "<br />");
Response.Write(SiteMap.RootNode.Url + "<br />");
// What nodes are children of the RootNode?
if (SiteMap.RootNode.HasChildNodes) {
IEnumerator rootNodesChildrenEnumerator = SiteMap.RootNode.ChildNodes.GetEnumerator();
while (rootNodesChildrenEnumerator.MoveNext()) {
// Prints the Title of each node.
Response.Write(rootNodesChildrenEnumerator.Current.ToString() + "<br />");
}
}
}
