title: Triggering resize of jqGrid after user shows/hides columns
body: <p>In jqGrid, after a users chooses to remove a column(s), a grid's width becomes smaller.  Therefore, I think it would be appropriate to trigger a resize at this point using <code>$("#myGrid").trigger("resize")</code>. However, <strong>to what jqGrid event should I attach this?</strong></p>
  
  <p>I tried triggering a resize manually on the Firebug Console after using the Column Chooser and it worked well.</p>
  
  <p>I also tried the recommendations in <a href="https://stackoverflow.com/questions/5515899/jqgrid-with-columnchooser-how-to-prevent-autoresize-after-columns-choice">this question</a> but without any results.</p>
