add your comments to a list view control:
<asp:ListView ID="lv" DataSourceID="dsCommnets" runat="server">
<ItemTemplate>
<%#Eval("Rate") %>
<%#Eval("COMENT") %>
<%#Eval("DATE") %>
<%#Eval("USER") %>
</ItemTemplate>
</asp:ListView>
this is up to you how style this!
and if in database you put ID identity on auto increasement , put datasource sorting on Ascending.
