关键代码：

        /// <summary>        /// 隐藏CheckBox        /// 说明        /// 在CustomDrawNodeCheckBox事件中使用        /// eg:        /// TreeList _curTree = (TreeList)sender;        /// _curTree.HideCheckBox(n => n.GetNodeType() == NodeType.Area || n.GetNodeType() == NodeType.CabsGroupRoot, e);        /// </summary>        /// <param name="tree">TreeList</param>        /// <param name="conditionHanlder">委托</param>        /// <param name="e">CustomDrawNodeCheckBoxEventArgs</param>        public static void HideCheckBox(this TreeListNode tree, Predicate<TreeListNode> conditionHanlder, CustomDrawNodeCheckBoxEventArgs e)        {            if (conditionHanlder(e.Node))            {                e.Handled = true;            }        }

代码使用：

        void LHTree_CustomDrawNodeCheckBox(object sender, CustomDrawNodeCheckBoxEventArgs e)        {            TreeList _curTree = (TreeList)sender;            _curTree.HideCheckBox(n => n.GetNodeType() == NodeType.Area || n.GetNodeType() == NodeType.CabsGroupRoot, e);        }
