radtreeview with checkbox

[Federik]

Hi,

I need a radtreeview with checkboxes which allow to check a child only if its parent is checked.

Thanks & regards
Federik

Hi Federik,

Try the following Javascript to achieve your scenario.

JS:

<script type="text/javascript">
 function OnClientNodeChecking(sender, args)
  {
    if ((args.get_node().get_level() != 0) && (!args.get_node().get_parent().get_checked()))
    {
        args.set_cancel(true);
    }
    if (args.get_node().get_checked())
    {
        var nodes = args.get_node().get_allNodes();
        for (var i = 0; i < nodes.length; i++)
      {
        nodes[i].uncheck();
      }
    }
  }
</script>

Thanks,
Princy.
