How to deliver two params when I remote data with AJAX

[Chenkai]

   ds_par is the first node, and when I collapsed, I want to deliver two params to remote method like "public Node GetNode(string id, string name)", How can I to complete it? Thanks.

<script>

    var ds_sub={
        transport:{
           read:{url:"http://......"},
           dataType:"json",
           data:{ how to use params of parent}
        },
       schema:{ 
          model:{
              NodeId:"NodeId",
             NodeName:"NodeName"
            }
    }
    var ds_par={
         transport:{
           read:{url:"http:...."}
        },schema:{model:{children:"ds_sub"}}
     }


</script>

Hi Chenkai,

This could be achieved by subscribing to the TreeView's collapse event. Once the event is triggered you can get the collapsed node through the handler's arguments and its respective dataItem, then pass it to the server using an AJAX request.
