ASP.NET MVC View Issue

I am trying to resolve the error 'List ActiveOrder02 does not contain a definition for Client' that appears when I put the mouse over '.Client' on the line @Html.DisplayNameFor(model => model.ActiveOrders02.Client) in the following View:

@model MVCDemo2.ViewModels.Order02VM

<table class="table">
<tr><th>@Html.DisplayNameFor(model => model.ActiveOrders02.Client)</th></tr>

@foreach (var item in Model.ActiveOrders02)
{
    <tr>
        <td>@Html.DisplayFor(modelItem => item.Client)</td>
    </tr>
}

For info here are the Controller and the ViewModel:

using MVCDemo2.Models;
using MVCDemo2.ViewModels;
using System.Linq;
using System.Web.Mvc;

namespace MVCDemo2.Controllers
{
public class Order02Controller : Controller
{
    private InventoryContainer db02 = new InventoryContainer();
    // GET: Order02
    public ActionResult Index()
    {
        //Create instance of the (View)Model
        var o = new Order02VM();
        //Retrieves DATA from the DB
        var resultSet02 = db02.SampleDbTable;
        // Push the retrieved DATA into the (View)Model
        o.ActiveOrders02 = resultSet02.Select(x => new ActiveOrder02
        {
            ID = x.tableId,
            Client = x.tableClient
        }).ToList();
//EDIT caused by answer of @David
        return View(o);
//IT WAS:            return View(o.ActiveOrders02.ToList());
    }
}
}

Here follows the ViewModel:

using System.Collections.Generic;

namespace MVCDemo2.ViewModels
{
public class Order02VM
{
    public List<ActiveOrder02> ActiveOrders02 { get; set; }
}

public class ActiveOrder02
{
    public decimal ID { get; set; }
    public string Client { get; set; }
}
}

EDIT: What I'm after is by DisplayNameFor to present the name of column tableClient from SampleDbTable as a Header of column Client in the Index view.

Thank you!
