检测右键单击工具条按钮 [英] Detect right click on toolstrip button

问题描述

我有一个带有上下文菜单的工具栏和一个带有click事件的工具栏按钮. 最初，我尝试将上下文菜单分配给按钮本身，但是在其属性中找不到上下文菜单. 因此，我将上下文菜单分配给了工具栏. 现在，每当我右键单击要显示上下文菜单的按钮时，都会触发按钮单击事件. 我想检查单击了哪个鼠标按钮，所以我很累于将事件args强制转换为mouseeventargs:

I have a toolstrip with a context menu and a toolstrip button in it with a click event. Initially I tried to assign the context menu to the button itself, but couldn't find a context menu in its property. So I assigned the context menu to the toolstrip. Now whenever I right click the button for the context menu to appear, the button click event is triggered. I want to check which mouse button is clicked, so I tired to cast event args to mouseeventargs:

if (((MouseEventArgs)e).Button != MouseButtons.Left) return;

但是我有一个例外，我无法执行此强制转换. 我可以将上下文菜单分配给按钮还是可以检测单击了哪个鼠标按钮? 谢谢

but I got an exception that I can't do this cast. Can I either assign context menu to the button or detect which mouse button is clicked? Thanks

推荐答案

您可以像这样尝试ToolStripButton的MouseDown事件:

You can try the MouseDown event of the ToolStripButton like this:

private void toolStripButton1_MouseDown(object sender, MouseEventArgs e){
   if(e.Button == MouseButtons.Right){
      //...
   }
}
