[RESOLVED] UpdateProgress not working under Updatepanel control.?

[PPCC]

Dear All,

In my aspx page I have UploadFile, Button and a Gridview. I have embedded all controls in Updatepanel control but upon selecting file in UploadFile control, Upon click of the button UpdateProgress text message does not work whereas without using Updatepanel it works very fine.

What could be the reason? and solution for this.

see the code below:

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" >
                        <ContentTemplate>
                            <table border="0" cellpadding="0" cellspacing="0" style="width: 100&#37;;">
                                <tr>
                                    <td>
                                        <asp:Panel ID="Panel2" runat="server" GroupingText="Production Scheduling(Excel File)"
                                            Width="100%" Font-Bold="True" Font-Size="Larger" BorderColor="navy">
                                            <table id="Table1">
