asp.net - using Eval of ASP Listview as an inline CSS value -

my code :

<asp:listview id="lst1" runat="server">   <itemtemplate>     <div style="width:<%#eval("rating")%>%">     </div>   </itemtemplate> </asp:listview>

it works great, in visualstudio editor it's considered invalid. there way make valid?

i know can create whole ' style="width:xxx%" ' in eval i'm looking way.

 <div style='<%# eval("rating", "width:{0}%") %>'></div>

it make accepted editor, don't know else though.
