Question

I have a simple Sitemap like this from asp:SiteMapDataSource:

Page 1 > Page 2 > Page 3

I would like to create foreach loop in C# that generates it instead for using asp:SiteMapPath because I need to add some exceptions to it. Now I cannot figure out how do I loop backwards from SiteMap.CurrentNode to SiteMap.RootNode?

The property you are looking for is SiteMapNode.ParentNode

SiteMapNode currentNode = SiteMap.CurrentNode; SiteMapNode rootNode = SiteMap.RootNode; Stack<SiteMapNode> nodeStack = new Stack<SiteMapNode>();  while (currentNode != rootNode) {     nodeStack.Push(currentNode);      currentNode = currentNode.ParentNode; }  // If you want to include RootNode in your list nodeStack.Push(rootNode);  SiteMapNode[] breadCrumbs = nodeStack.ToArray();
