title: Handling a Click for all controls on a Form
body: <p>I have a .NET UserControl (FFX 3.5).  This control contains several child Controls - a Panel, a couple Labels, a couple TextBoxes, and yet another custom Control.  I want to handle a right click anywhere on the base Control - so a right click on any child control (or child of a child in the case of the Panel).  I'd like to do it so that it's maintainable if someone makes changes to the Control without having to wire in handlers for new Controls for example.</p>
  
  <p>First I tried overriding the WndProc, but as I suspected, I only get messages for clicks on the Form directly, not any of its children.  As a semi-hack, I added the following after InitializeComponent:</p>
  
  <pre><code>  foreach (Control c in this.Controls)
    {
      c.MouseClick += new MouseEventHandler(
        delegate(object sender, MouseEventArgs e)
        {
          // handle the click here
        });
    }
  </code></pre>
  
  <p>This now gets clicks for controls that support the event, but Labels, for example, still don't get anything.  Is there a simple way to do this that I'm overlooking?</p>
