    I have recently upgraded a project to Telerik.Web.UI.dll 2013.3.1015.40.  Our RadWindows are opened through a common handler function which calls set_visibleStatusbar(false), this no longer works if I set RenderMode to auto in web.config and view in a modern browser.  I have verified by manually getting a reference to the window in the browser console and calling the method directly, the status bar does not disappear.

    The status bar does disappear if I set the RenderMode to classic in web.config or set VisibleStatusbar="false" in the aspx.

    This seems like a bug to me, anything I might have overlooked?

    Hi Rob,

    Unfortunately I couldn't replicate the issue at my end. Please have a look into the sample code I tried which works fine at my end.

    <telerik:RadWindow ID="RadWindow1" runat="server" Title="Details">
    <telerik:RadButton ID="RadButton1" runat="server" Text="ShowWindow" OnClientClicked="OnClientClicked1"

      <add key="Telerik.Web.UI.Window.RenderMode" value="lightweight" />

    <script type="text/javascript">
        function OnClientClicked1(sender, args) {
            var win = $find("<%=RadWindow1.ClientID %>");

    Here is a screenshot of it not working.  I'll open a support ticket so I can upload the code.

    Hi guys,

    I can confirm this is a bug with the lightweight render mode and I have logged it for fixing.

    In the meantime I can offer two workarounds:
    - set the VIsibleStatusbar property of the RadWIndowManager to false, if all your RadWindows need no statusbar


    - use the following script if some do and you need to hide it for the rest:
    oWnd = window.radopen(pageURL, winName);
    //will work for classic rendermode
    //will work for lightweight. In classic jQuery will not throw exceptions because of the element it cannot find
    $telerik.$(".rwStatusBar", oWnd.get_popupElement()).hide();
    var contentElem = $telerik.$(".rwContent.rwExternalContent", oWnd.get_popupElement());
    contentElem.height(contentElem.height() + 20);

    In Shinu's sample the visibility of the statusbar is toggled before the UI of the control is rendered (i.e., shown for the first time), which is why it worked. After the call to show() (or radopen() or, of course) the set_visibleStatusbar(false) call will not work.
