dynatree: how to pass uniqueId for WebForm_DoCallback(first param,...) to onActivate: function (node)

Question

I want to call WebForm_DoCallback method when node is clicked

$("#tree").dynatree({
    onActivate: function (node) {
        ..something..
        WebForm_DoCallback(uniqueId, callBackArgument, ReceiveCallBackData, "", null, true);
 });

The idea is to pass the node.key to a asp.net page. I am new in jquery and all that callback stuff, so please tell me if the whole approach is wrong :)

Answer 1

I found it!

I created javasrcript class and property that receive uniqueId of the page. Then i pass that property to WebForm_DoCallback method.
