Using DisplayFor inside a for each loop

Question

I have the following view:-

@foreach(var info in Model.Firewall.FirewallCustomers.OrderBy(a=>a.CustomerName)){

<td>@Html.DisplayFor(info.CustomerVLAN.VLANID)</td>
}

But I am unable to write the following

@Html.DisplayFor(info.CustomerVLAN.VLANID)</td>

I will get the following error:-

The type arguments for method 'System.Web.Mvc.Html.DisplayExtensions.DisplayFor(System.Web.Mvc.HtmlHelper, System.Linq.Expressions.Expression>)' cannot be inferred from the usage. Try specifying the type arguments explicitly

So can anyone advice , how to use DisplayFor inside my foeach loop ?

Thanks

Try replacing var with the type of info in the foreach — acfrancis

DisplayFor needs an expression. Try this:

@foreach(var info in Model.Firewall.FirewallCustomers.OrderBy(a=>a.CustomerName)){
    <td>@Html.DisplayFor(model => info.CustomerVLAN.VLANID)</td>
}

Here, model is a lambda expression parameter, and even though it's not actually used in the lambda expression, this syntax is needed to construct the expression.
