Problem is AssociatedUpdatePanelID . You havn't set Associateid of your 'UpdateProgress`
set it on UpdateProgress
<asp:UpdateProgress ID="UpdateProgress" runat="server" AssociatedUpdatePanelID="Upnl1">
As per MSDN
The UpdateProgress control renders a element that is displayed or hidden depending on whether an associated UpdatePanel control has caused an asynchronous postback. For initial page rendering and for synchronous postbacks, the UpdateProgress control is not displayed.
EDIT:
Reason is <asp:PostBackTrigger ControlID="btnShowReport" />
Which will cause a full page postback. You should change your Trigger to
<asp:AsyncPostBackTrigger ControlID="btnShowReport" />
and it will do the job for you...If you could have read the quoted statement you would have able to solve it by yourself too...
