Podarilo sa mi nájsť na internete. Ak to niekomu pomôže:

  #region Select item TreeView pravým tlačítkom
        private void TreeView_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
        {
            TreeViewItem treeViewItem = VisualUpwardSearch(e.OriginalSource as DependencyObject);
            if (treeViewItem != null)
            {
                treeViewItem.Focus();
                e.Handled = true;
            }
        }
        static TreeViewItem VisualUpwardSearch(DependencyObject source)
        {
            while (source != null && !(source is TreeViewItem))
                source = VisualTreeHelper.GetParent(source);
            return source as TreeViewItem;
        }
        #endregion
