title: How do I add a ContextMenuStrip to a ToolStripButton?
body: <p>I have a toolstrip containing, among other things, a ToolStripComboBox and a ToolStripButton.  I want to add a ContextMenuStrip to both of them, but I don't have direct access to the toolstrip or its other contents, so I can't set the context menu of the toolstrip.</p>
  
  <p>Setting the ContextMenuStrip for the ToolStripComboBox is easy:</p>
  
  <pre><code>myToolStripComboBox.ComboBox.ContextMenuStrip = myContextMenu;
  </code></pre>
  
  <p>but there's no obvious equivalent for the ToolStripButton.  How do I add a ContextMenuStrip to a ToolStripButton?</p>
