Solution

The most simple way is to place a class on your Date Text box, and just use jQuery to add the datepicker...

<EditItemTemplate>
<asp:TextBox ID="txtDate" CssClass="clDate" 
  runat="server" Text='<%# Eval("DATE","{0:dd.MM.yyyy}") %>'></asp:TextBox>
</EditItemTemplate>

and the javascript for init this is: $(".clDate").datepicker(); but the update panel is need again initialization after the Update, so the final code will be:

<script type="text/javascript"> 
   // if you use jQuery, you can load them when dom is read.
   $(document).ready(function () {
       var prm = Sys.WebForms.PageRequestManager.getInstance();    
       prm.add_initializeRequest(InitializeRequest);
       prm.add_endRequest(EndRequest);

       // Place here the first init of the DatePicker
       $(".clDate").datepicker();
    });        

    function InitializeRequest(sender, args) {
       // make unbind to avoid memory leaks.
       $(".clDate").unbind();
    }

    function EndRequest(sender, args) {
       // after update occur on UpdatePanel re-init the DatePicker
       $(".clDate").datepicker();
    }
</script>
