I have a xmlhttppanel loading inside a radajaxloading panel and then a radgrid inside the xmlpanel. When there is a selection in the radgrid made it triggers a grid selected function which is where the onservicerequest is made. The problem is the panel.set_value is showing the panel null even though I am using the var panel = $find("<%=xmlPanel1.ClientID %>"); any ideas??

<asp:Content ID="Content1" ContentPlaceHolderID="cphHead" Runat="Server">
   
    <script type="text/javascript">
        function rdGrid1_RowSelected(sender, args) {
            var StartDate = args.getDataKeyValue("Start Date");
            var EndDate = args.getDataKeyValue("End Date");
            var panel = $find("<%=xmlPanel1.ClientID %>");
            panel.set_value(StartDate + '|' + EndDate);
        }
        </script>

   
    <style type="text/css">
        .style1
        {
            font-size: medium;
            font-weight: bold;
        }

        .divContainer
        {
            width: 100%;
            height: 160px;
            position: relative;
        }
        .divGrid, .divXmlHttpPanel
        {
            position: absolute;
            top: 2px;
            left: 0px;
        }
        .divXmlHttpPanel
        {

            left: 170px;
        }

Hello Jeff,

I created a sample page with the code you provided, but I am unable to reproduce your problem. The client-side object of the RadXmlHttpPanel appears to be referenced correctly.  Please check the attached test page and let me know if there are any differences, compared to your project. Here you can find a screen capture of the RadXmlHttpPanel on my end.

I will need to reproduce the problem on my end in order to help you accordingly. Please try modifying the attached sample so that it matches your case. If this is not possible, you can also send a simple, runnable page that isolates the issue so that I can examine it locally and provide a more to the point answer. I would suggest opening a support ticket in order to send a sample.

All the best,
Slav
