Error/Login page appearing in RadWindow

[Michael]

Hello,

We use radwindows in several places in our application.  Errors cause a redirect either to our login page or to an error page.  Most common is due to session timeout. 

It is a problem when this happens while the user is in a radwindow and the radwindow itself displays the login page.   We have fixed this for IE by placing this javascript on our login page:

 

<script type="text/javascript">
        if (window != window.top) window.top.navigate(window.location.href);
</script>

This doesn't work on Mozilla.  This may be because mozilla creates each window on a seperate thread and thinks that the radwindow IS the top window?

Can you please advise how we can handle this issue.

Thanks

Hi Michael,

I am not sure what your exact scenario is, but to manipulate the parent window you first need to get a reference to it. RadWindow offers a user-friendly API that enables you to easily achieve that - its BrowserWindow property.

For your convenience I created and attached a small sample that redirects the browser window upon a click of a button (you can use the same logic, just call the function when appropriate in your custom scenario). To get the URL of the RadWindow you can use its get_navigateUrl() method.

Kind regards,

Hello Marin,

Thank you for the assistance.  Again the issue is when a session had expired and the user opens a rad window and finds the login page inside the rad window.  I am attempting to have them redirect with the main window.

Thank you for the code sample.   I have to run the code at the start of the page to see if the  window that got there was a radwindow or the main browser window.  When I would navigate to the login page normally it would give me errors that radWindow is undefined or null.

I made some modifications do the code you provided that seems to work but I'm not at all good with javascript and can you advise if this is a good solution.  I left my previous code there commented out.

Thank you

<script type="text/javascript">
    //if (window != window.top) window.top.navigate(window.location.href);
    var oWindow = null;
    if ("radWindow" in window)
        oWindow = window.radWindow;
    else if (window.frameElement != null) {
        if ("radWindow" in window.frameElement) {
            oWindow = window.frameElement.radWindow;
        }
    }
    if (oWindow != null) {
        oWindow.BrowserWindow.location = '<%= Page.ResolveUrl(Paths.Login) %>';
    }
</script>

Hi Michael,

If I understand you scenario correctly this JavaScript function is run when the login page is opened. If so this seems to be a good check whether the user has been redirected within a RadWindow or within the browser window.

Without your actual logic I cannot confirm if this will always produce the desired result, but based on the provided information it seems as a good solution.

I hope your project is going well. If you have further issues with our controls do not hesitate to contact us again.

All the best,
