    I have a page with Radtreeview enable drag & drop. I implement a radconfirm to check exist node name when drop nodes

    Script on client node dropping

    function onNodeDropping(sender, args) {
               var dest = args.get_destNode();
               var source = args.get_sourceNode();
               if (dest) {
                   var result = false;
                   for (var i = 0; i < dest.get_nodes().get_count() ; i++) {
                       var node = dest.get_nodes().getNode(i);
                       if (node.get_text() == source.get_text()) {
                           result = true;
                   if (result) {
               else {

    And code to call confirm :

    function callConfirm(nodeText) {
                            radconfirm(nodeText + ' folder is existing, Do you want to overwrite?', confirmCallBackFn);
                            return false;
                        function confirmCallBackFn(arg) {
                            var ajaxManager = $find("<%=RadAjaxManager1.ClientID%>");
                       if (arg) {
                       else {

    Code of RadAjaxManager1_AjaxRequest
    if (e.Argument.ToString() == "ok")
                    lbStatus.Text = "OK";
                else if(e.Argument.ToString() == "cancel")
                    lbStatus.Text = "Cancel";

    But when drop an item on Radtreeview to another Node that the same node name, RadTreeView_NodeDrop event always fire before RadAjaxManager1_AjaxRequest. How to solve it?

    Update: Confirmbox show on the same time with RadTreeView_NodeDrop event fire.

    I want them follow with sequence :
    User drag item to others node > if it has same node name > show confirm box > User choose Yes or No > fire event RadAjaxManager1_AjaxRequest > fire event RadTreeView_NodeDrop

    But current sequence is :User drag item to others node > same node name > show confirm box + fire event RadTreeView_NodeDrop

    Hi Huy,

    I suggest you cancel the OnClientNodeDropping event in case the user click on the "Cancel" button in the radconfirm window. This way you will no longer need OnAjaxRequest event and you can move your server logic in the RadTreeView_NodeDrop event and
