hiding the asyncupload container and persisting upload

I have a wizard-like screen that has several steps. The first step includes an async-upload. I have set the PostbackTriggers property so that only the submit button on the last step causes the file to be uploaded. This all works fine to persist the file upload through the postbacks associated with the Next/Previous buttons of the wizard, however, the way the wizard works is to hide/show panel controls depending on which step is currently being viewed. If I set the panel.visible property to false for the panel which contains the async-upload, I notice when I return to this step by setting panel.visible to true, the upload is gone. I have found one potential workaround by setting panel.Style("display") = "block" or "none" depending on whether I want to hide it or not and this seems to persist the upload. I would prefer to use the built-in asp.net visible property. I am wondering if this is a known limitation or am I doing something wrong?

MegaMenu and Literal

I am using the demo of the mega menu and now that I have it built one of the sub-menus I want to have it filled via a custom list. I put a literal in and can't access the literal. I am sure I am missing something simple. The menu section is below. Thanks, John

Usercontrol on dynamically created dock return Null Reference Exception

Hello,

I'm creating a 'dashboard' on which the user can dynamically add dock controls. Each dock control contains a certain usercontrol.

Using the examples from the Telerik site, I already have created the dashboard and the functionality to add dock controls. But when I add a usercontrol, I get a null reference exception form the usercontrol. The usercontrol itself contains several buttons, which are null when I call dockLayout.Controls.Add(dock);
I'm not sure, but I think it has to do with the state of the page lifecycle.

The dock-widget example (http://www.telerik.com/help/aspnet-ajax/dock-widgets.html) I've using is probably the way to solve this problem, but the example doesn't explain how LoadControl() should be implemented. Is this the missing link? If so, can you give an example code, based on the provided example?

<asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server">
    <telerik:RadAjaxLoadingPanel runat="server" ID="ralpConfiguration">
    </telerik:RadAjaxLoadingPanel>
 
    <telerik:RadAjaxPanel runat="server" ID="rapConfiguration" LoadingPanelID="ralpConfiguration">
          <telerik:RadWindow ID="modalPopup" runat="server" Width="360px" Height="360px" Modal="true">
               <ContentTemplate>
                    <asp:DropDownList runat="server" ID="ddlControls" ></asp:DropDownList>
                    <asp:Button runat="server" ID="btnAddRadDock" Text="Add" />
               </ContentTemplate>
          </telerik:RadWindow>
     </telerik:RadAjaxPanel>
 
    <telerik:RadDockLayout ID="dockLayout" runat="server">
    </telerik:RadDockLayout>

// the following line will trigger the page load of the user control, which in turn returns the null ref exception on a button within the user control
