Sometimes you need to select and show (i.e. bring into the view) an item from a data bound TreeView immediately on initial load.

Please note that with the current Q3-2009 release calling the ExpandAll, the ContainerFromItemRecursive and even the GetItemByPath methods will not work for you. To work this around you should rely on a combination shown below:
 
this.treeView1.ExpandItemByPath(People.pathXMan, People.PathSeparator);
RadTreeViewItem container = this.treeView1.GetItemByPath(People.pathXMan);
if (container != null)
{
    container.BringIntoView();
    container.IsSelected = true;
}
 
We prepared (and attached to this article) a small example where a hierarchical item is selected in a data bound TreeView on initial load.
