OnClientClose client script not firing

[Mark]

Need some help...

Here's the js to open my rad window (working great)

function GetRadWindow(){
   var oWindow = null;
   if (window.radWindow) oWindow = window.radWindow;
   else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
   return oWindow;
}

function OpenRadWindow(url, modal, width, height, name, cancelReturnValue, title, refresh, refreshElement, onClose) {
    var oManager = GetRadWindowManager();
    if (oManager == null) {
        alert("No Rad manager is available");
        return;
    }
    Wnd = oManager.open(url, name);
    Wnd.setSize(width, height);
    Wnd.set_title(title);
    Wnd.setActive(true);
    Wnd.SetModal(true);
    Wnd.set_showContentDuringLoad(true);
    Wnd.center();
    Wnd.refresh = refresh;
    Wnd.cancelReturnValue = cancelReturnValue;
    Wnd.returnValue = cancelReturnValue;
    if (onClose!=null) Wnd.add_close(onClose);
    if (refreshElement==null) refreshElement = "custom";
    Wnd.refreshElement = refreshElement;
}

Here's my code that SHOULD be firing when the window closes:

<telerik:RadCodeBlock ID="cb1" runat="server">
    <script type="text/javascript">
        function refreshCustomFields(sender,eventArgs)
        {
          var ajaxManager = $find("<%= rapCustom.ClientID%>");
          ajaxManager.ajaxRequest(eventArgs);
        }
    </script>
</telerik:RadCodeBlock>

So, window opens great, when I close it, it should fire the "refreshCustomFields" JavaScript method which in turn will trigger an AjaxRequest on my RadAjaxPanel.  However, I get the following error in Firefox:

Error: a[b] is not a function

And this error in IE 8 (Windows 7)

The client script "refreshCustomFields" is in the source and the add_close(onClose) gets called and set properly when the window opens (JavaScript debugger).  But I get errors when I close the window.  Any help would be appreciated.

Hi MJ,

Your code looks fine. Have you checked if your refreshCustomFields() function is executed? What happens when you put a standard alert in it - does it fire at all?

If you still experience problems, please open a support ticket and send us a small sample project where this issue could be reproduced. We will check it and do our best to help.

refreshCustomFields() doesn't fire at all.  I'll give it another go and open a support ticket if it still doesn't work.

OK MJ,

We'll be expecting your project - once we receive it, we will do our best to help.

Did this ever get resolved?  I'm seeing the same issue when attempting to close a RadWindow.

Never mind, found my problem - passing in the function name as a string instead of as a function.  For anyone that runs across similar issues, here's a utility function I wrote as I was researching the issue:

function getFunctionFromName(fnName) {
    if (typeof fnName === 'function') return fnName;
    if (typeof fnName === 'string' && typeof window[fnName] === 'function') return window[fnName];
    return null;
}

It returns null if nothing is found, which of course is typeof object, because the rest of our window popup code is checking explicitly for null rather than checking for undefined.  You may want to adjust that bit for use elsewhere.
