    Hello everyone.

    I'm using a Window on my page that has a Rotator in it. The Rotator is bound to a LINQ data set. It worked fine,
    but then I tried to put an AJAX Loading Panel to show a "loading" image while the rotator is bound and I get the following error:

    The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

    I tried using a RadCodeBlock without luck.

    Here is my code:

    (Main .aspx page)

    <telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
        <script type="text/javascript">
            function openWin()
                var oWnd = radopen("SCARLog.aspx", "RadWindow1");

    <telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false"
    ReloadOnShow="true" runat="server" Skin="Hay" EnableShadow="true">
            <telerik:RadWindow ID="RadWindow1" runat="server" Behaviors="Close" NavigateUrl="Log.aspx">

    (.aspx window page)
    <body height="100%" scroll="no" style="overflow:hidden;" scrooltop="oTop" >
    <title>Detail Log</title>

    <telerik:RadScriptManager ID="RadScriptManager1" runat="server" ></telerik:RadScriptManager>

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

    <telerik:RadFormDecorator ID="RadFormDecorator1" DecoratedControls="All" runat="server" Skin="Hay" />

    <asp:Panel ID="Panel1" runat="server" HorizontalAlign="Center" Height="275px">
    <telerik:RadRotator ID="Rotator" runat="server" Skin="Hay" ScrollDirection="Up"
    RotatorType="AutomaticAdvance" FrameDuration="3000" Width="300px" ItemWidth="302px" Height="100px" ItemHeight="100px">
        <div style="text-align:center">
            <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
                <asp:Label ID="lblDate" runat="server">Date: <%# DataBinder.Eval(Container.DataItem,"DateChanged") %></asp:Label>
        <div style="text-align:center">
            <asp:Label ID="Label2" runat="server">User ID: </asp:Label>
            <telerik:RadCodeBlock ID="RadCodeBlock2" runat="server">
                <asp:Label ID="lblUser" runat="server"><%# DataBinder.Eval(Container.DataItem, "UserID")%></asp:Label>
        <div style="text-align:center">
            <asp:Label ID="Label3" runat="server">From status: </asp:Label>
            <telerik:RadCodeBlock ID="RadCodeBlock3" runat="server">
                <asp:Label ID="lblFrom" runat="server"><%# DataBinder.Eval(Container.DataItem, "FromStatus")%></asp:Label>
        <div style="text-align:center">
            <asp:Label ID="Label4" runat="server">To status: </asp:Label>
            <telerik:RadCodeBlock ID="RadCodeBlock4" runat="server">
                <asp:Label ID="lblTo" runat="server"><%# DataBinder.Eval(Container.DataItem, "ToStatus")%></asp:Label>

    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" BackgroundPosition="Center" EnableSkinTransparency="true">
        <asp:Image id="Image1" runat="server" ImageUrl="~/images/Loading.gif" ></asp:Image>



    (.aspx.cs code)

    if (!this.IsPostBack)
        Int32 Snum = Convert.ToInt32(Session["IDNumber"].ToString());
        using (Entity db = new Entity())
            var data = from L in db.Log
            where L.IDNumber == Snum
            orderby L.DateChanged
            select new
            Rotator.DataSource = data;
