You can use an AsyncPostBackTrigger with the UpdatePanel to do this.
try some thing like this:-

without any hidden button;-

__doPostBack('<%=UpdatePanel1.ClientID %>', null);

or with hidden button:-

XML

<asp:UpdatePanel ID="UpdatePanel1" runat="server" >
    <ContentTemplate>

    </ContentTemplate>
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="ReloadThePanel" EventName="Click" />
    </Triggers>
</asp:UpdatePanel>
<asp:Button ID="ReloadThePanel" runat="server" style="display:none;" />

When you want the panel to be updated, you just need to call:

__doPostBack('<%=ReloadThePanel.ClientID %>', null);
