How to stop refreshing whole page while using timer & trigger in asp.net

I am using update panel,timer and trigger to show top 5 songs of the week one by one but due to the Timer_Tick event of the trigger the whole web page is not working fine means when I slide the scroller down it automatically comes up means the page is getting refreshed and due to which scroller automatically comes to its initial position.I am writing the code below.Please give any suggestion where I'm going wrong.
Thanx in advance.

  <asp:Timer ID="Timer1" runat="server" Interval="2000" OnTick="Timer1_Tick">
  </asp:Timer>
                                
 <asp:ScriptManager ID="ScriptManager1" runat="server">
 </asp:ScriptManager>
                                 
 <asp:UpdatePanel ID="UpdatePanel1" runat="server">
 <Triggers>
           <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
                                        
 </Triggers>
 <ContentTemplate>
