You will need to add the Triggers as shown below to the UpdatePanel, or remove it from the UpdatePanel all together.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
   <Triggers>
      <asp:PostBackTrigger ControlID="CrystalReportViewer1" />
   </Triggers>
   <ContentTemplate>
      <CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="true" />
   </ContentTemplate>
</asp:UpdatePanel>
