    The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
    The question is: Do I need a special configuration is IIS OR with      routing sloved this problem

<asp:HyperLink ID="Fsyllab" NavigateUrl='<%# `String.Format(Eval("FCourseID","~/ReDownload/{0}/" +  Eval("FCourseName") + `".doc" ))%>'   target="_blank"  runat="server" Width="20px"  Height="10px"
 ImageUrl="/Images/main/download.png" CommandArgument='<%# `Eval("FCourseID") %>'  Font-Underline="false" Text='<%# `Eval("FCourseDuration").ToString()  %>' />

routes.MapPageRoute(
         "products1-browse1", "ReDownload/{id}/{name}", "~/ReDownload.aspx",true);
