    RadControls version 2012.2.724.35

    If you are using RadTreeView as a site map and at the times of reloading / post-back / opening a new RadTab / Browser window / Browser tab, following code keeps the current node selected.

    Of course the RadTree needs to be in the master page

    Well we can definitely use this functionality for one more purpose.

    Assume that you are working on some wholesale management system and you have node "Invoices" for example, which in turn has enlisted all the her invoices  as the child nodes. And if you wish to "highlight" the particular node which refers to the invoice currently open, the code above should work.

    Alternative approach:
    This may also be accomplished by saving the node id / name to a cookie / session variable and then retrieving it to the other page / tab / radtab.

    Main reason for this post
    I posted a related question in forums for 3/4 days or so and was not able to find exactly what I wanted, all posts talked about using "SelectedNode.Selected=true;" which seemed to be working if we navigate to a new Browser window / Browser tab, or even a new RadTab.
