title: HoverMenuExtender doesn't show up from within hidden table cell
body: <p>I've programmatically added a column to a GridView for the sole purpose of adding a HoverMenuExtender and Panel to it's cells.  The HoverMenuExtender displays when you hover over a row no problem.</p>
  
  <p>However, there is now an extra column in my grid that I don't want there.  I've tried 3 things to hide it:</p>
  
  <p>1) set the column to Visible=false on the server.  This doesn't work because the column will then not be rendered, so the HoverMenuExtenders don't exist on the page.</p>
  
  <p>2) set the cells of the column to visibility: hidden.  This almost works, but cells still occupy the same space on the page as when they are visible(as they should with visibility).</p>
  
  <p>3) set the cells of the column to display: none.  This hides the column but prevents the hoverMenu from displaying for some reason.</p>
  
  <p>So my question is, why does option #3 prevent the HoverMenuExtender from displaying when I hover over the row?  </p>
  
  <p>Wouldn't the HoverMenuExtender have to mark the popup div/panel as display:none anyway and then change that when the target is hovered over?</p>
  
  <p>Any ideas would be great, I'm just curious.  Thanks for reading...</p>
