【c# winform】devexpress treeList右键菜单添加按钮
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
}
