    Is it possible to make a treeview with checkboxes, but only on certain levels?
    like not on first and second level, but on 3 or 4 level/ or all other levels below second level.

    Thanks

    Hello Bjorn,

    One approach is to hook onClientLoad event and loop through each nodes. There you can check for the node level and access the checkbox element and hide it . Here is a same script which hides the first level CheckBoxes.

    Javascript:
    <script type="text/javascript">
    function OnClientLoad(sender, args)
      {
            for (var i = 0; i < sender.get_allNodes().length; i++)
            {
                if (sender.get_allNodes()[i].get_level() == "1")
                {
                    sender.get_allNodes()[i].get_checkBoxElement().style.display = "none";
                }
            }
        }
    </script>

    Thanks,
    Princy.
