{
private static string GetBackLink(SiteMapNode parentNode)
{
return "<li class='li-back'><a href='" + parentNode.Url + "' title='" + parentNode.Title + "'></a></li>";
}
public static string Menu(this HtmlHelper helper)
{
var sb = new StringBuilder();
SiteMapNodeCollection siteMapNodeCollection;
sb.Append("<ul>");
SiteMapNode currentNode = SiteMap.CurrentNode;
if (!SiteMap.CurrentNode.Equals(SiteMap.RootNode))
{
if (!SiteMap.CurrentNode.HasChildNodes)
sb.Append(GetBackLink(SiteMap.CurrentNode.ParentNode.ParentNode));
else
sb.Append(GetBackLink(SiteMap.CurrentNode.ParentNode));
}
if (!SiteMap.CurrentNode.HasChildNodes)
siteMapNodeCollection = SiteMap.CurrentNode.ParentNode.ChildNodes; …Run Code Online (Sandbox Code Playgroud)
