<telerik:RadPanelBar runat="server" ID="RadPanelBar1" Skin="Mac" Height="100%" ExpandMode="FullExpandedItem" 
OnItemDataBound="RadPanelBar1_OnItemDataBound"
     
</telerik:RadPanelBar> 
<asp:XmlDataSource ID="xdsSummary" runat="server" XPath="Summaries/Items/Summary" EnableCaching="false" /> 

I am populating the RadPanelBar above as such:
this.xdsSummary.DataFile = "http://mywebservice/myService.asmx/GetSummaryContainer?acct=1234"
RadPanelBar1.DataSource = this.xdsSummary; 
RadPanelBar1.DataBind(); 

The DataFile for the xml datasource returns:
             <?xml version="1.0" encoding="utf-8" ?>  
<Summaries xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
<Items> 
<Summary> 
  <Title>Title 1</Title>   
  </Summary> 
<Summary> 
  <Title>Title 2</Title>    
  </Summary>-  
  </Items> 
  </Summaries> 

I then bind the Title of the RadPanel:
    protected void RadPanelBar1_OnItemDataBound(object sender, Telerik.Web.UI.RadPanelBarEventArgs e) 
    { 
        System.Xml.XmlElement xmlElement = e.Item.DataItem as System.Xml.XmlElement; 
 
        foreach (System.Xml.XmlNode node in xmlElement.ChildNodes) 
        { 
            if (node.Name == "Title"
                e.Item.Text = node.InnerText; 
        } 
    } 

Now, within each of the Panel, I want to call another web service asynchronously and display some text. The web service returns string as such;
  <?xml version="1.0" encoding="utf-8" ?>  
  <string><div id="WidgetContent"<script type="text/javascript"> //<![CDATA[ Sys.WebForms.PageRequestManager._initialize('ctl02$ScriptManager1', document.getElementById('ctl01')); Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90); //]]> </script> <div> <table cellspacing="0" border="0" id="ctl02_DetailsView1" style="border-collapse:collapse;"<tr> <td colspan="2"><b>Account Type:</b></td><td></td</tr></table</div> </div> <script type="text/javascript"> //<![CDATA[ Sys.Application.initialize(); //]]> </script></string>  

How can I do this?

Thanks

Hi Howard,

You can use  the ScriptManger control to call a web service which will return you some data(text or array).
Please see here for more details.

Then you can subscribe to the SucceededCallback event  and create an item in its event handler by using the data returned form the web service:

for example:
function SucceededCallback(result)  
{  
       var panel = $find("RadPanelBar1");  
       var item = new Telerik.Web.UI.RadPanelItem()'  
       item.set_text(result);  
       panel.get_items().add(item);  
 
}  
 

Hope this helps.

Kind regards,
