Try to use uploadify's onAllComplete event to refresh your update panel from client-side code. For that purpose add onto the page button, add AsyncPostbackHandler for this button to updatepanel's triggers collection and fire click on this button programmatically in uploadify onAllComplete event handler:

$('#fuFiles').uploadify({
    onAllComplete: function (event, data) { $("#<%= HiddenButton.ClientID %>").click(); return true; },
    uploader: 'Scripts/uploadify.swf',
    script: 'FileUploads.aspx',
    cancelImg: 'Scripts/cancel.png',
    auto: 'true',
    multi: 'true',
    buttonText: 'Browse...',
    queueSizeLimit: 5,
    simUploadLimit: 2
});


<asp:Button runat="server" ID="HiddenButton" Style="display: none;" />

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false">
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="HiddenButton" />
            </Triggers>
