鼠标右键功能 contextMenuStrip 控件

转自：http://blog.163.com/qiaoqiaoyouxiang@126/blog/static/132607431201062692649980/

ContextMenuStrip 控件提供了与某个控件关联的快捷菜单。也就是说通过这个控件可以方便的实现在别的控件上弹出右键快捷菜单。

例子：

1、先添加一个ContextMenuStrip 控件到Form上

2、设置目标控件（如窗体、文本框等）的ContextMenuStrip属性，指向你刚才添加的ContextMenuStrip 控件。这样就实现了两者的关联。

3、动态将一些菜单项添加到 ContextMenuStrip  控件中，如：

//上下文菜单项

ContextMenuStrip1.Items.Add(msEditNew);//ToolStripItems

ContextMenuStrip1.Items.Add(msEditBar1);//ToolStripItems

ContextMenuStrip1.Items.Add(msEditCut);//ToolStripItems

ContextMenuStrip1.Items.Add(msEditPaste);//ToolStripItems

ContextMenuStrip1.Items.Add(msEditDelete);//ToolStripItems

ContextMenuStrip1.Items.Add(msEditBar2);//ToolStripItems
