Hello Zahi,

You should create the RadXmlHttpPanel control in the Page_Init. Then you should attach an event handler to the ServiceRequest server-side event or set the WebMethodName and WebMethodPath in case you are using WebServices. Here is a sample project that shows how to dynamically create a RadXmlHttpPanel control:

.aspx

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head id="Head1" runat="server">

<title></title>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function SetValue()

{

var panel = $find("RadXmlHttpPanel1");

panel.set_value("test");

}

</script>

</telerik:RadScriptBlock>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<input value="Set Value" onclick="SetValue(); return false;" type="button" />

<div>

</div>

</form>

</body>

</html>

.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using Telerik.Web.UI;

public partial class Dynamic_XmlHttpPanel : System.Web.UI.Page

{

protected void Page_Init(object sender, EventArgs e)

{

RadXmlHttpPanel xmlPanel = new RadXmlHttpPanel();

xmlPanel.ID = "RadXmlHttpPanel1";

xmlPanel.EnableClientScriptEvaluation = true;

xmlPanel.ServiceRequest += new XmlHttpPanelEventHandler(xmlPanel_ServiceRequest);

xmlPanel.WebMethodName = "";

xmlPanel.WebMethodPath = "";

form1.Controls.Add(xmlPanel);

}

protected void xmlPanel_ServiceRequest(object sender, RadXmlHttpPanelEventArgs e)

{

Label lbl = new Label();

lbl.ID = "Label1";

lbl.Text = DateTime.Now.ToString();

RadXmlHttpPanel panel = (RadXmlHttpPanel)sender;

panel.Controls.Add(lbl);

}
