How to call jquery function from server code with no clicks/links

How to call jquery function from server code with no clicks/links

Hi,
 
I am new to Jquery.
 
I have a small jquery popup function which I am using for displaying help file. It works fine when I
call it from getfocus of a control.
 
I would like to call the same or similar function from ASP server code to display a message after a successful update.
 
I would like to display the popup without hitting a button or link.
 
How do I accomplish call that function from asp server side using c#.
 
 function showPopup() {
        ShowPopup();
        setTimeout(HidePopup, 2000);
    }


Thanks
Suresh
