Hello,
             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?..

Thanks,
Bharani

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
    }
</script>
