    Hi, I've started to try RadAjaxLoadingPanel, but it does work. I use MS Visual Studio 2010.
    Loading pannel does nothing when I click button.

    The Code I have tried is:


    <%@ Page Language="c#" CodeBehind="TesU.aspx.cs" Inherits="ASOI.TesU" %>
    <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/tr/xhtml11/DTD/xhtml11.dtd">
    <html xml:lang="en-US" xmlns="http://www.w3.org/1999/xhtml">
    <head id="Head3" runat="server">
        <style type="text/css">
                background-color: #dff3ff;
                border: 1px solid #c6e1f2;
    <body class="BODY">
        <form runat="server" id="Form2" method="post">
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server" />

          <telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1" IsSticky="false"
                EnableViewState="true" Enabled="true" MinDisplayTime="2000">
                <img id="imgLoader" src="Images/loading.gif" />

        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                <telerik:AjaxSetting AjaxControlID="Buttton1">
                        <telerik:AjaxUpdatedControl ControlID="Panel1" LoadingPanelID="RadAjaxLoadingPanel1" />

        <fieldset class="module1">
            <asp:Panel ID="Panel1" runat="server" HorizontalAlign="Center" Height="275px">

          <asp:Button ID="Button1" runat="server" Text="Click to see the loading image" OnClick="Button1_Click"
                    Style="margin-top: 15px; margin-left: 15px"  />


    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;

    namespace ASOI
        public partial class TesU : System.Web.UI.Page
            protected void Page_Load(object sender, EventArgs e)


            protected void Button1_Click(object sender, EventArgs e)

    Could anybody tell me, please, what I do wrong?

    Hello Denis,

    Please verify that you are pointing to the correct existing image into the Image folder. Find attached a small application which uses your code and works as expected.

    All the best,
