    Your HTML Table is incorrectly formed. You have no <tr> elements, but the real problem probably lies with your style attributes, please see my updated code below.

    You can find a good example of how to accomplish what you are trying to do here: http://blogs.visoftinc.com/2008/03/13/Modal-UpdateProgress-for-UpdatePanel-Revisited/

    Try adjusting your code to the following:

    <asp:UpdatePanel ID="SendMailUpdatePanel" runat="server">
    <ContentTemplate>
        <div style="float: right;">
            <asp:Button ID="btnSend" runat="server" Text="Send" ToolTip="Send "
                Visible="false" Font-Bold="True" OnClick="btnSendResume_Click" />                          
            <asp:Button ID="btnDown" runat="server" Text="Download IDs" ToolTip="follow-up"
                Visible="false" Font-Bold="True" OnClick="btnDownloadEmailIDs_Click" />
        </div>
    </ContentTemplate>
</asp:UpdatePanel>
<asp:UpdateProgress ID="UpdateProgress2" runat="server" AssociatedUpdatePanelID="SendMailUpdatePanel">
    <ProgressTemplate>
        <div id="blur" style="position:fixed; top:0px; bottom:0px; left:0px; right:0px; overflow:hidden; padding:0; margin:0; background-color:black; filter:alpha(opacity=50); opacity:0.5; z-index:1000;" />
        <div id="progress" style="position:fixed; top:30%; left:43%; width:14%; z-index:1001; background-color:white; border:solid 1px black; padding:5px; text-align:center;">
            <b>Mail in progress.Please Wait...</b>
            <br />
            <br />
        </div>
    </ProgressTemplate>
</asp:UpdateProgress>
