篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了WPF 托盘图标右键弹出的ContextMenu如何关闭相关的知识，希望对你有一定的参考价值。
我在托盘加入了NotifyIcon控件，在Click事件中加入了contextMenu.IsOpen=true;这样来打开右键菜单。
我想在弹出菜单后，鼠标点击其他位置时，菜单自动消失，请问怎么做？
我的系统托盘里，其他软件图标都是右键点击后，弹出菜单，点击其他位置菜单消失。
我只能实现右键点击弹出菜单，但是点击其他位置菜单不消失，怎么办？我尝试了菜单在LostFocus时context.IsOpen=false;这样也不行。
谢谢~！
System.Windows.Forms.ContextMenuStrip contextMenu = new System.Windows.Forms.ContextMenuStrip();
System.Windows.Forms.ToolStripMenuItem item1 = new System.Windows.Forms.ToolStripMenuItem();
item1.Click += new EventHandler(item1_Click);
item1.Text = "显示主面板";
System.Windows.Forms.ToolStripMenuItem item2= new System.Windows.Forms.ToolStripMenuItem();
item2.Text = "退出";
item2.Click += new EventHandler(item2_Click);
contextMenu.Items.Add(item1);
contextMenu.Items.Add(item2);
this.notifyIcon.ContextMenuStrip = contextMenu; 参考技术A LostFocus 基本没用的,WPF里面没有NotifyIcon控件,你用的,应该是从Winform里面拿过来的对吧?那样就要自己判断全局的鼠标事件,程序加载时,设置全局监听钩子.只能这样处理.
bootstrap treeview 和Table 击右键弹出菜单
本文参考了Bootstrap Styled Context Menu Plugin With jQuery 并且在该网页上下载了bootstrap-contextmenu.js.
contextmenu 实现击右键弹出子菜单。 它可以和bootstrap-treeview以及table 结合起来使用。
测试过的代码：
