title: KendoUI TreeList Change Expand/Collapse Icon
body: <p>Im trying to change the default expand/collapse icons to bigger icons. I've set the following css change which doesnt seem to be taking any effect:</p>
  
  <pre><code>.k-treelist .k-minus {        
       background: url('../img/Misc/customCollapsedIcon.png') center center;
  }
  
  .k-treelist .k-plus {
      background: url('../img/Misc/customExpandedIcon.png') center center;
   }
  </code></pre>
  
  <p>Can anyone give me some advice on what I need to change for this to take affect on  the TreeList?</p>
