    RadComboBox not rendered (Rendered as "") when within asp panel with initial visible= false.

    The asp panel is set to visible= true when postback is triggered via client using ajaxManager.ajaxRequest('InitialPageLoad'

    protected void Page_Load(object sender, EventArgs e)
                // register ajax
                Telerik.Web.UI.RadAjaxManager ajaxMgr_CCF =   Telerik.Web.UI.RadAjaxManager.GetCurrent(Page);
                ajaxMgr_CCF.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(AjaxRequestsForCCF);



    protected void AjaxRequestsForCCF(object sender, AjaxRequestEventArgs e)
               if (e.Argument == "InitialPageLoad")
                  pnlWithComboBox.Visible = true;


     RadCombobox is always set to visible = true.

    The panel has other server side control but they render fine. 

    If I set radComboBox1.visible = true then it works fine. But should it automatically render and no need for setting specificly

    <asp:Panel ID="pnlWithComboBox" runat="server" visible="false">
            <telerik:RadComboBox ID="radcombobox1" runat="server"                                   Width="123px" RenderMode="Lightweight"                                    OnSelectedIndexChanged="btnSavePlaybackForward_Click" AutoPostBack="true" OnClientSelectedIndexChanged="comboBoxContext">
                                            <telerik:RadComboBoxItem Text="1" Value="1" runat="server" />
                                            <telerik:RadComboBoxItem Text="2" Value="2" runat="server" />
                                            <telerik:RadComboBoxItem Text="3" Value="3" runat="server" />

    function initializePage(sender, eventArgs) {                 var ajaxManager = $find('<%= RadAjaxManager.GetCurrent(this.Page).ClientID %>');                 ajaxManager.ajaxRequest('InitialPageLoad');   

    <telerik:AjaxSetting AjaxControlID="radAjaxManager1">  
            <telerik:AjaxUpdatedControl ControlID="pnlWithComboBox"  />
