Hiding Control In Master Page When in RadWindow

[Brian Mains]

Hello,

I have a control in a master page that I want to display only when the master page is not in a RadWindow; when in a RadWindow, it should be hidden.  Is that possible to do, to detect when the page request is inside the RadWindow?

Thanks.

Hello Brian,

Such check can be done on the client only - there isn't a server-side method that would detect how the HTML is rendered - in the topmost page or in some container like IFRAME.
To detect on the client if a page is loaded in a RadWindow, you could use a slightly modified version of the GetRadWindow() function:

<script type="text/javascript">
    function GetRadWindow()
    {
        var oWindow = null;
        if (window.radWindow) oWindow = window.radWindow;
        else if (window.frameElement && window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
        return oWindow;
    }

    function CheckWnd()
    {
        var wnd = GetRadWindow();
        if (wnd)
        {
            alert("This page is loaded in a RadWindow");
        }
        else
        {
            alert("The page is loaded in the browser");
        }
    }
</script>
