Answer 1

Try decreasing the time after which the ProgressTemplate is displayed. By default this is 5 seconds. This behaviour is controlled by the Property: DisplayAfter

Specify the number of milliseconds to elapse before showing the progress control, i.e 2000 if you wish to wait for 2 seconds

<asp:UpdateProgress DisplayAfter="2000" AssociatedUpdatePanelID="UpdtBank"
     id="updateProgress" DynamicLayout="true" runat="server" />
