Try this..

ASP.NET

<asp:TemplateField>
               <ItemTemplate>
                   <asp:Label ID="lbl" runat="server" Text='<%#     Eval("Promised_Date_Time") == "1/1/1999"? "":Eval("Promised_Date_Time")  %>'></asp:Label>
               </ItemTemplate>
           </asp:TemplateField>

it did not worked karthik.. actually value of Promised_Date_Time is "1/1/0001 12:00:00 AM".. I tried it this way.
<asp:TemplateField HeaderText="Promise Date Time">
<itemtemplate>
<asp:Label ID="lblPromisedDateTime" runat="server" Text='<%# Eval("Promised_Date_Time")=="1/1/0001 12:00:00 AM"?"":Eval("Promised_Date_Time") %>'>

but the value 1/1/0001 12:00:00 AM is still shown.. can it not be done using template field???
