I am currently launching a window (named "rwAttachmentsMaster" in the example below) from within a window (named "rwRequestMasterpage" in the example below), and trying to get it to update the first window when the second window is closed, without much luck.

I have both windows declared in a window manager, which is in my masterpage, and am using the following code -

    
            function LaunchAttachments() {  
        
                    var parent = GetRadWindow().BrowserWindow;  
        
                    var attach = parent.radopen("Attachments.aspx", "rwAttachmentsMaster");  
        
                    setTimeout(function() { attach.setActive(true); }, 100);  
        
                    attach.add_close(function() { UpdateAttachmentCount(); });  
        
                }  
        
                function UpdateAttachmentCount() {  
        
                    var requestWindow = GetRadWindowManager().BrowserWindow.getWindowById("rwRequestMasterpage");  
        
                    requestWindow.get_contentFrame().contentWindow.UpdateAttachmentCountStep2();  
        
                }  
        
                function UpdateAttachmentCountStep2() {  
        
                    var label = document.getElementById("<%= lblNumAttachments.ClientID %>");  
        
                    label.value = "x";  
        
                }

All of that code is currently sitting in the page you get when you open the first window. I'm not entirely sure if that is where it is all meant to go or not.

That demo works great, and has enabled me to achieve my functionality, but it has uncovered a new problem with it.

In the demo, Dialogue2 is closed via a button, which runs the following script (slightly adapted to meet my needs) -

    
            function UpdateAttachmentsCount() {  
        
                    //Get a reference to the parent page (Default.aspx)   
        
                    var oWnd = GetRadWindow();  
        
                    if (getQstring("updateattachments", "") != "") { // the getQstring function simply gets a querystring value  
        
                        //get a reference to the second RadWindow  
        
                        var dialog1 = oWnd.get_windowManager().getWindowByName(getQstring("updateattachments"));  
        
                        // Get a reference to the first RadWindow's content  
        
                        var contentWin = dialog1.get_contentFrame().contentWindow  
        
                        //Call the predefined function in Dialog1  
        
                        contentWin.UpdateAttachmentCount(document.getElementById("<%= hfRowCount.ClientID %>").value);  
        
                    }  
        
                    //Close the second RadWindow  
        
                    oWnd.close();  
        
                }

Now, this works great as a button, but if I try to assign that function to the close button via add_close(), it does not work. How would I go about getting the same functionality to occur when pressing the X in the corner of the window?

So, in summary, I am trying to accomplish the following -

Open Window1 from MainPage (which I can do fine)
Open Window2 from Window1 (which I can do fine)
Click X button in corner of Window2 and have it pass back info to Window1 (this produces errors)
