title: How to capture hovermouse event in designmode for winform UserControl
body: <p>I'm building a user control with two control inside it (a Label and a textbox).  When a user drags the user control onto a WinForm, I want to allow them to use their mouse as a splitter control to control the label/textbox proportions in the box.  I tried to wire up the hover event in the control, but it's only in affect during runtime..  How can I do it in DesignMode.???

  Example:</p>
  
  <pre><code>    private void NgoUserControl_MouseHover(object sender, EventArgs e)
      {
          Control c = sender as Control;
          Point pos = c.PointToClient(Cursor.Position);
  
          c.Cursor = Cursors.SizeWE;
  
          //
          // resize logic
          // 
      }
  </code></pre>
