本文提供俩种不需要手动添加编辑控件方法。
方法一：创建新的右键菜单添加“执行选择”按钮，且抑制TreeList自带菜单
结果展示：
代码：
private void Form1_Load(object sender, EventArgs e) { CreateBarButtonItem(); } private void CreateBarButtonItem() { // 创建右键菜单 ContextMenuStrip contextMenuStrip = new ContextMenuStrip(); // 添加 "执行选择" 菜单项 ToolStripMenuItem execSelectedItem = new ToolStripMenuItem("执行选择"); execSelectedItem.Click += ExecSelectedItem_Click; ; contextMenuStrip.Items.Add(execSelectedItem); // 关联右键菜单与 TreeList 控件 treeList1.PopupMenuShowing += TreeList1_PopupMenuShowing; } private void TreeList1_PopupMenuShowing(object sender, PopupMenuShowingEventArgs e) { // 禁用自带的右键菜单 e.Allow = false; } private void ExecSelectedItem_Click(object sender, EventArgs e) { //处理“执行选择”事件逻辑 }
方法二：在TreeList自带菜单基础上添加“执行选择”按钮
结果展示：
右键空节点
右键节点，保留自带菜单功能
右键列标题，保留自带菜单功能
代码：
private void Form1_Load(object sender, EventArgs e) { treeList1.PopupMenuShowing += TreeList1_PopupMenuShowing;//自定义右键展示菜单 } private void TreeList1_PopupMenuShowing(object sender, PopupMenuShowingEventArgs e) { // 获取右键菜单 if (e.Menu is TreeListMenu menu) { // 添加自定义按钮 DXMenuItem execSelectedItem = new DXMenuItem("执行选择"); execSelectedItem.Click += ExecSelectedItem_Click; // 将自定义按钮插入到菜单的末尾 menu.Items.Add(execSelectedItem); } } private void ExecSelectedItem_Click(object sender, EventArgs e) { //处理“执行选择”事件逻辑 }
