    This happens when the focused node's parent node is deleted by TreeList.DeleteNode,
    seems the FocusedNode property is not updated in this case.

      use the following function to replace TreeList.DeleteNode will fix the bug:
             internal static void DeleteNode(TreeListNode node)
             {
                 List<TreeListNode> listNode = new List<TreeListNode>(node.Nodes);
                 foreach (TreeListNode nodeChild in listNode)
                     DeleteNode(nodeChild);
                 node.TreeList.DeleteNode(node);
             }
