Detect right click on toolstrip button

问题

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;

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

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

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