dropdownlist in firefox

Hi all,
i have a ddl
<asp:DropDownList ID="ddl1" runat="server" CssClass="Dateinput" TabIndex="2"> <asp:ListItem>dd/MM/yyyy</asp:ListItem> <asp:ListItem>MM/dd/yyyy</asp:ListItem> <asp:ListItem>dd MMM yyyy</asp:ListItem> <asp:ListItem>dd MMMM yyyy</asp:ListItem> </asp:DropDownList> In firefox the first letter in the ddl is showing uppercase Dd/MM/yyyy but i gave as dd/MM/yyyy. what should i do to represet the same dd/MM/yyyy in ddl in firefox.
Same way in my application, if the data am getting from data base consider student is my data and am binding to ddl, it shows Student. S uppercase where as i save in DB as student.
Please any one can provide me the solution for this

Thanks,
Vishal
