You have to set Timer1.Enabled = false; in finally block

    protected void Timer1_Tick(object sender, EventArgs e)
    {
        try
        {
           // your code ............
        }
        catch
        {             
        }
        finally
        {
            divLoading.Visible = false;
            Timer1.Enabled = false;
        }
    }

I'm a little unclear on what you need here - but what I think you're asking for is you'd like a button to be clicked on the client side, have a 20 second wait period on the client side while your timer is still running, then submit the page for processing. If this is what you want it has to be fully client driven - the timer isn't "running" in the server code. This is all based on the assumption that you're talking about an AJAX timer...

If this is what you're asking for, the following code should get you there:

        function onButtonClick(e) {
            var evt = Sys.UI.DomEvent.isInstanceOfType(e) ? e : new Sys.UI.DomEvent(e);
            if(evt.target["_doClick"] === true) {
                // just let the event happen 
                // (still w/ button disabled to prevent double click)
                evt.target["disabled"] = "disabled";
                evt.target["_doClick"] = false;
                alert('the real click');
            } else {
                evt.target["disabled"] = "disabled";
                evt.target["_doClick"] = true;
                evt.preventDefault();
                evt.stopPropagation();
                var t = evt.target;
                setTimeout(function () { t["disabled"] = ""; t.click(); }, 20000);
            }
        }
