MVCSiteMapProvider - show title of parent node

Question

I would like to be able to show the title of the parent of the current node.

Sitemap:

    <mvcSiteMapNode title="Main Site Tile" controller="Home" action="Index">
  <mvcSiteMapNode title="Some site section" controller="Section" action="Index">
    <mvcSiteMapNode title="Some page" controller="Section" action="Page1" />
    <mvcSiteMapNode title="Some other page" controller="Section" action="Page2" />
  </mvcSiteMapNode>
</mvcSiteMapNode>

So, on 'Page1' I can show the title (Some page) by using:

Html.MvcSiteMap().SiteMapTitle()

Great. But, I would also like to show the title of the parent node (Some site section) in my _Layout page, so this would appear the same if I were viewing 'Page1' or 'Page2' (or indeed any view nested within).

Is this possible?

Answer 1

You can do this using the SiteMapTitle attribute and set the Target to ParentNode.

[MvcSiteMapProvider.Web.Mvc.Filters.SiteMapTitle("SomeKey", Target = AttributeTarget.ParentNode]
public ViewResult Show(int blogId) { 
   ViewData["SomeKey"] = "This will be the title";

   var blog = _repository.Find(blogId); 
   return View(blog); 
}

That will set the title of the links in the Menu and SiteMapPath.

You can also access the nodes programmatically using the static SiteMaps object.

var theTitle = MvcSiteMapProvider.SiteMaps.Current.CurrentNode.ParentNode.Title;

Alternatively, you can use the FindSiteMapNodeFromKey("theKey") method to find any node in the SiteMap to get its title.
