Working with data-bound TreeView involves one confusing moment - SelectedItem do not refers to a RadTreeViewItem but an item from the ItemsSource collection. To access the related tree-view item we have to address the ContainerFromItemRecursive method:

object item = myTree.SelectedItem; 
if (item != null) 
{ 
    RadTreeViewItem tvi = myTree.ContainerFromItemRecursive(myTree.SelectedItem); 
    if (tvi != null) 
    { 
        // here we can deal with the tree-view item 
        // ... 
    } 
} 

According to this state we should care when accessing SelectedItem property.

In attached archive you can find an example how to access the Container of SelectedItem.

Note: Data-binding of the TreeView control is realized as it is described in the How to Databind RadTreeView in WPF article.
