    Hi,
           I am using a tree view where the nodes are using a context menu with two options "Delete"and "View". Depening on certain condition I need to remove the "Delete" menu option from some of the nodes. Could you please let me know how to achieve that?

    Thanks

    Hi Hemangajit,

    I suggest you subscribe to OnClientContextMenuShowing event of the treeview and show/hide the "Delete" item in its handler:

    <script type="text/javascript">
        function contextMenuShowing(sender, args) {
            if (//condition)
                args.get_menu().findItemByText("Delete").set_visible(false);
            else
                args.get_menu().findItemByText("Delete").set_visible(true);
        }
    </script>
