    I am having a hell of a time getting this to work correctly.  I have a RadWindow that can be launched from any site on the page (the link resides on a master page) and will bring up a login window.

    When the user successfully logins in, the SQL reader will set a variable in session and then once the data reader has closed SHOULD redirect to a page based on what is stored in the session variable.

    So I need to be able in my code behind to say If Session("ThisValue") = Something then Close RadWindow and redirect parent.

    I have this code in the RadWindow:
        <script type="text/javascript">
            function RedirectUser(sender, args) {
                GetRadWindow().BrowserWindow.location.href = '../ThisPageWhenRedirectUser.aspx';
                GetRadWindow().close();       //closes the window    
            }
            function GetRadWindow()   //Get reference to window 
            {
                var oWindow = null;
                if (window.radWindow)
                    oWindow = window.radWindow;
                else if (window.frameElement.radWindow)
                    oWindow = window.frameElement.radWindow;
                return oWindow;
            }    
    </script>

    I just don't know how to call that from my code behind.  I am trying it like so:

    'after database has retrieved and stored the value in session
    If (Session("UserType") = Something Then CloseRadAndRedirect()
     
    Public Sub CloseRadAndRedirect()
            If (Not ClientScript.IsStartupScriptRegistered("GetRadWindow")) Then
                ScriptManager.RegisterStartupScript(Page, Me.GetType(), "GetRadWindow", "RedirectUser();", True)
            End If
        End Sub

    This does not work.  In fact it simply refreshes the radwindow and the controls lose their formatting and styles.

    Any help would be greatly appreciated.

    Hello,

    One suggestion is you can try to close the RadWindow on client side and redirect to the parent page as shown using RadAjaxManager.
    JS:
    function windowclose()
       {   
         var win = $find("<%= RadWindow1.ClientID %>");
         win.close();
         var mngr = $find("<%= radajaxmngr.ClientID %>");
         mngr.ajaxRequest(arguments)
     }
    C#:
    protected void radajaxmngr_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)
       {
           if ( Session["temp"]==" ")// check your condition here
           {
               Response.Redirect("~/sample/mainPage.aspx");
           }
       }

    Thanks,
    Princy.

    Hi Shawn,

    The first thing I notice in your snippet is that it calls the RedirectUser() function, while in your JavaScript it does not exist, you have RedirectUser() instead. Also, the call to check if the script is registered is not necessary and it may not even be entering the body of the if statement in your case. You can also examine this help article on calling a JavaScript function from the server. Please also make sure you do not have some JavaScript error on the page and if so - resolve it first. Alternatively, you may simply redirect the topmost frame without ever referencing the RadWindow with the following simple line:  window.top.location.href = "yourUrl.aspx";
