How to retrieve the date only (without the time) in a textbox

Hi All
I would like to display a date entered in my db in the following txtBox:
<asp:textbox id="txtDOB" runat="server" Text='<%# Eval("DOB") %>'></asp:text But the text box displays:
    09/01/1980 00:00:00
 I've tried both;
      Text='<%# Eval("DOB", "{0:dd-MMM-yyyy}") %>'
      dataformatstring="{0:dd/MM/yyyy}"
but this still returns the Time.  Am I missing something?
 
Please help
