It seems you messed up your code. Try to keep it simple and then try again:

    <asp:UpdateProgress runat="server" id="PageUpdateProgress1" AssociatedUpdatePanelID="UpdatePanel1" DynamicLayout="false">
<ProgressTemplate>
Processing Request from Update 1. Please Wait..
</ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel runat="server" id="UpdatePanel1">
<ContentTemplate>
<asp:Button runat="server" id="UpdateButton" onclick="UpdateButton_Click" text="Update 1" />
</ContentTemplate>
</asp:UpdatePanel>


    protected void UpdateButton_Click(object sender, EventArgs e)
    {
      System.Threading.Thread.Sleep(5000);
    }
