[WinForm][DevExpress][TreeList]条件隐藏节点CheckBox_.NET_编程开发_程序员俱乐部

关键代码：

class="csharpcode">        /// <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);
        }
