    On the website there seems to be missing an explicit explanation that After you do an CallbackUpdate you have to add a Javascript function where you do a so your notification window could be seen on clientside.


    Hello, I started using RadNotification control today and I have encountered a problem that is really weird.

    The problem is that I am using a really simple implementation of this control using a callback method on the server, and this the notification doesn't Fire up when the event ends... in Fact it never FIRES up anytime the event ends.

    Here is my code (I used the same code provided in the Demo website) REF:

    The only difference is that I am not using the QuickStart Library or Event Log Console.


    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="ListaBase.UserControls.WebForm1" %>
    <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
    <head runat="server">
        <form id="form1" runat="server">
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
        <br />
        <telerik:RadNotification ID="RadNotification1" runat="server" LoadContentOn="TimeInterval"
            Width="300" Animation="Fade" EnableRoundedCorners="true" EnableShadow="true"
            Title="Received messages" OffsetX="-20" OffsetY="-20"
            TitleIcon="none" UpdateInterval="3000" AutoCloseDelay="1500" OnCallbackUpdate="OnCallbackUpdate">
                <asp:Literal ID="lbl" runat="server"></asp:Literal>

    namespace ListaBase.UserControls
        public partial class WebForm1 : System.Web.UI.Page
            protected void Page_Load(object sender, EventArgs e)
            protected void OnCallbackUpdate(object sender, RadNotificationEventArgs e)
                int newMsgs = DateTime.Now.Second % 10;
                if (newMsgs == 5 || newMsgs == 7 || newMsgs == 8 || newMsgs == 9) newMsgs = 0;
                lbl.Text = "You have " + newMsgs + " new messages!";
                RadNotification1.Value = newMsgs.ToString();

    Nice post!
    Didn't see this anywhere else, but you can also explicitly show it a button
