value binding to property in cshtml

I have a view model having 2 properties: one is a list of items class objects and the other one is an object of order class. I want to show the sum of the price calculated from items' list in order.price

Here is view model:

public class PlaceOrderViewModel
{
    public Orders Order { get; set; }
    public List<Items> Items { get; set; }
}

Here is items model:

public class Items
{
    public long Id { get; set; }
    public long OrderId { get; set; }
    public int ItemType { get; set; }
    public string Detail { get; set; }
    public int ItemsCount { get; set; }
    public int Price { get; set; }
}

I am looking for something like this,

@Html.DisplayFor(model => model.Order.Price, new { Value = @Model.Items.Sum(s => s.Price)})

I did try this but this doesn't work for me.

I want to bind the sum value with the order.price property. Any help?

Let's say you have this:

public class Order
{
    public int Id { get; set; }
    public List<Items> Items { get; set; }
    ...
    public int TotalPrice 
    {
        get
        {
             return Items == null ? 0 : Items.Sum(p => p.Price);
        }
    }
}

And in your view should have:

@Html.DisplayFor(model => model.Order.TotalPrice)
