Hi I have a site with a two aspx pages and a masterpage.
on the masterpage I have a treeview with a list of categories and when a category is selected I get a list of topics with a intro on each post.
URL example category: www.site.com/sports/soccer/europe/
categories can go three-four levels deep and if I click a specific post I get into the post.aspx
URL example post: www.site.com/post/2342-Zlatan-scores-again
What I want to do is when im in the Post page I want to highlight the category to which it belongs in the treeview...but considering that each post is not in the sitemap file it just looses focus...so how can I set the selected treeview node to be
www.site.com/sports/soccer/europe/ when im on the

On clicking posts of particular category, get the category of that post and store it into Session variable.
Now, in master page's Page_Load event, get category from Session variable and set the selected node accordingly.

Make sure that the TreeView is getting populated before setting the selected node.

I tried using a Session variable and put it in page_load doesnt work...am I suposed to use
Treeview1.SelectedNode.NavigateUrl = Session["Category"];
but I still get Object not set to a reference of an object...If I remove this line...I have the treeview visible with all categories collapsed and I print the value of the session variable so those two things work so basically it feels like that the tag
Treeview1.SelectedNode.NavigateUrl is not the right attribute to select a node.
is this something you can confirm or am I in the wrong...I really need to fix this...I have built the entire website and have everything working but this minor snag and I cant figure it out...so this is the only thing I have to fix before taking this site

Refer this link to set the SelectedNode :
Also, debug the application and before setting the SelectedNode, check whether TreeView is populated or not.
