                 I have a tree with several nodes. I have function OnNodeClick to get the selected node. But I also want the node that lost focus. How do I get that information?..

    Hello Bharani,

    The last selected item can be retrieved from client side "OnClientNodeClicking" handler. Save the value in a global location (Eg:HiddenField) and access it from code behind.

    Client code is shown here:
    <script type="text/javascript">
        function OnClientNodeClicking(sender, args) {
            var text = args.get_node().get_text();
            if (sender.get_selectedNode() != null)
                alert(sender.get_selectedNode().get_text()); // get the last selected node
