Hi,

I am having an asp ajax update panel and rad loading panel. I am using the below code to show the loading panel during ajax requests. I have a timer which keeps polling a DB for a specific interval.

Situation:

If the page is inactive for a long time, the session expires, but the timer is still polling the DB. Due to the session expiry or due to some error from the server, a script error is thrown. How do i handle this in the below code?

    
            <script>  
        
                    var loadingPanel = "";  
        
                    var pageRequestManager = Sys.WebForms.PageRequestManager.getInstance();  
        
                    var postBackElement = "";  
        
                    pageRequestManager.add_initializeRequest(initializeRequest);  
        
                    pageRequestManager.add_endRequest(endRequest);  
        
                    function initializeRequest(sender, eventArgs) {  
        
                        loadingPanel = $find('<% = RadAjaxLoadingPanel1.ClientID %>');  
        
                        postBackElement = eventArgs.get_postBackElement().id;  
        
                        loadingPanel.show(postBackElement);  
        
                        }  
        
                    }  
        
                    function endRequest(sender, eventArgs) {  
        
                        loadingPanel = $find('<% = RadAjaxLoadingPanel1.ClientID %>');  
        
                        loadingPanel.hide(postBackElement);  
        
                    }  
        
            </script>
