entity framework - Formatting Date on Html.TextBoxFor - other solutions not working -

using ef-generated classes, here's metadata class:

    [displayname("approved date")]     [datatype(datatype.datetime)]     [displayformat(applyformatineditmode = true,                             htmlencode = false,                             nulldisplaytext = "",                              dataformatstring = "{0:mm/dd/yyyy}")]     public object approveddate{ get; set; } 

the view:

<%: html.editorfor(model => model.standard)%> 

the editor:

<%:html.editorfor(model => model.approveddate)%> 

the datetime.ascx:

<%string name = viewdata.templateinfo.htmlfieldprefix;%> <%string id = name.replace(".", "_");%>  <div class="clear">     <div class="editor-label"><%:html.labelfor(model => model)%></div>     <div class="editor-field">         <%:html.textboxfor(model => model)%>         <%= html.validationmessagefor(model => model)%>     </div> </div>  <script type="text/javascript">     $(document).ready(function () {          $("#<%=id%>").datepicker({             showon: 'both',             dateformat: 'm/d/yy',             changemonth: true,             changeyear: true         });     }); </script> 

nothing seems work. have maintain binding, don't want raw html.

all date fields output same formatting, includes time.
