Question

I have a SiteMap with All my nodes. I’m using a TreeView control which is linked to the SiteMap for navigation. Now I would like to hide certain nodes from appearing on the TreeView. Is it possible to do this?

Yes, it’s definitely possible. The way we do it is to add a custom ‘IsPhantom’ attribute to the nodes we don’t want shown in the sitemap (and in various other places too):

<siteMapNode url='~/Welcome.aspx' title='Welcome' description='' isPhantom='true' /> 

Then in the sitemap control, use the following code to remove nodes that have the ‘IsPhantom’ attribute:

protected void Page_Load(object sender, EventArgs e) {     TreeView1.TreeNodeDataBound += new TreeNodeEventHandler(TreeView1_TreeNodeDataBound);                   SiteMapSource.Provider = this.CurrentProvider; }  protected void TreeView1_TreeNodeDataBound(object sender, TreeNodeEventArgs e) {     SiteMapNode thisMapNode = (SiteMapNode)e.Node.DataItem;     TreeNode parentTreeNode = e.Node.Parent;      if (thisMapNode['isPhantom'] != null && thisMapNode['isPhantom'].ToLower().Equals(bool.TrueString.ToLower()) && parentTreeNode != null)         parentTreeNode.ChildNodes.Remove(e.Node); }
