c# - MVCSiteMapProvider Breadcrumb with SiteMapPreserveRouteData disappears with the second item -

I have a MVC project and I am implementing a breadcrumb with the MVCSitmapprovider.

My MVC is following Sitemap:

  & lt; MvcSiteMapNode title = "index" controller = "index" action = "index" key = "index" & gt; & Lt; MvcSiteMapNode title = "parent" controller = "parent" action = "see" key = "parent" & gt; & Lt; MvcSiteMapNode title = "hair" controller = "hair" action = "view" /> & Lt; / MvcSiteMapNode & gt; & Lt; / MvcSiteMapNode & gt;   
 I've added the _layout view  
  @ html.mvcSiteMap (). SiteMapPath ()   
 When I return to the original item, the parameter needs to be protected in order to get the correct item. To do this, I added the annotation in the View function. SiteMapPreserveRouteData:  
  [SiteMapPreserveRouteData] Public Function View (Proxy ID)   
 Now, I can navigate my breadcrumbs using  
 The problem is that it only works with the first item when I change the item, the breadcrumbs disappear ...  
 Sample: I navigate to the original page 2 - & Gt; Child C1, and when I return to the index and select the parent 1, the parent page of the page does not show the breadcrumb.  
 If I extract annotation sitemapresarerRoutData, but the breadcrumb is lost then ID ..  
 Am I worning? some ideas?  
 Thank you

 The problem is most likely to be your approach, I use SiteMapPreserveRouteData Does not recommend - it is cruel power and more importantly, the approach taken in its design is faulty.  
 I have created a post which goes deeper in tracking the position of the user. In the sitemap - understanding the information of the post is important in making roti-tromba trails that do not disappear.
