Hi,

Unfortunately I cannot replicate the issue at my end. Here is the full code that I tried.

ASPX:

<telerik:RadGrid AutoGenerateColumns="true" ID="RadGrid1" runat="server" DataSourceID="SqlDataSource2" Visible="false">
 <ClientSettings>
     <ClientEvents OnGridCreated="GridCreated" /></ClientSettings>
</telerik:RadGrid>

C#:

protected void Button2_Click(object sender, EventArgs e)
   {
       RadGrid1.Visible = true;
   }

JS:

function GridCreated() {
       alert("fired");
   }

Thanks,
Shinu

Thanks Shinu for replay.

But I skip one information, my dynamically added UserControls are placed on RadAjaxPanel.
Here is a bit of my sample code:

C#

public partial class TestForm : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            btnTest.Click += new EventHandler(btnTest_Click);
            for (int i = 0; i < Counter; i++)
                AddControl();
        }
        public int Counter
        {
            get
            {
                int? cc = (int?)Session["counter"];
                return cc.HasValue ? cc.Value : 0;
            }
            set
            {
                Session["counter"] = value;
            }
        }
        void btnTest_Click(object sender, EventArgs e)
        {
            AddControl();
            Counter++;
        }
        private void AddControl()
        {
            Control ctrl = LoadControl(" path to my uc ");
            ajax.Controls.Add(ctrl);

        }

Aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TestForm.aspx.cs" Inherits="xxx.TestForm" MasterPageFile="~/MasterPages/MasterPage.Master"%>
<%@ Register Src="~/Controls/xxx/StatusUserControl.ascx" TagName="ucStatus" TagPrefix="uc" %>

</asp:Content>

Hello Rafal,

Please note that using RadAjaxPanel simultaneously with RadAjaxManager or UpdatePanel ( or implementing multiple wrapped RadAjaxPanels ) is not a supported scenario and we highly recommend to avoid such implementation. Please either use just the manager to update your controls replacing the RadAjaxPanel with a regular asp:Panel, or use the RadAjaxPanel alone to wrap your page.

I hope the clarification was helpful.
