Hello Telerik Team,
          I have a RadTreeView in which i want to trigger an event in Expand and Colapse
         i tried lot of jquery code but i cant access

jQuery('li.rtLI div > span:eq(2)').live('click', function () {
    //xyz
});
jQuery('li.rtLI div > span.rtPlus').live('click', function () {
    //xyz
});

 I hope this helps.

function ClientNodeExpanded(sender, eventArgs) {
        var node = eventArgs.get_node();
        alert("Parent node " + node.get_text() + " is expanded to show " + node.get_nodes().get_count()+ " child nodes");
    }
