  Hello,

  
  

  I am using load on demand (serversidecallback) to populate nodes, the issue i am having is that when a new node is loaded it will always show + next to it, even if it has no children.
  
  

  Is there a setting that I have to give a node so that it will hide this image if it has no children? 

  
  

  Is there a way to programatically show or hide these images?

  
  

  thanks very much

  
  

  Nick

  Hi Nick,
  
  Actually this is expected behavior since the subnodes are loaded on demand and you don't know in advance how many subnodes a node will have.
  
  All the best,

  thank you i understand that, but is there a way to programatically show or hide these images? or is it only possible editing the skin/css?

  
  

  thanks

  Hi Nick,
  
  I suggest you set ContentCssClass property to the node that doesn't need images:
  
  

  node.ContentCssClass="noSigns";

  
  and add  "noSigns"  css class to your page:
  
  

  <style type="text/css">

      div.noSigns .rtPlus,

      div.noSigns .rtMinus {

          display: none;

      }

   

  </style>
