[zhang]

I am using mvcgrid.i use popup edit.it works fine in IE .but when i change to Chrome,,
the TryUpdateModel methode in my controller dont work.
so i check in chrome to see the data posted back ,and i found a null key.
see the image bellow.
beside,i use a   tlerik editor in my edittemplate .it cause the Chrome send a
null key back.but it works well in IE.  

THIS IS MY EditorTemplates:
 @{ Html.Telerik().Editor()
        .Name("css")
        .HtmlAttributes(new { style = "height:300px;width:450px;" })
        .Encode(true)
       .Value(@<text>Model.css</text>) 
         .Render();
IT is SO simple,I do not know what is wrong.
