Your question isn't clear enough. Could you try and describe it again?

Don't understand you clearly but see you have some problems with adding order line to shopping cart. I would implement it as follows:

public class Order
    {
        public int Amount { get; set; }
        public Guid ProductId { get; set; }
    }

public class ShoppingCart
    {
        public List<order> Orders { get; set; }
        public void Add(Order order)
        {
            if (order == null) return;
            if (Orders.Where(p => p.ProductId == order.ProductId).Count() > 0)
            {
                var existedOrder = Orders.Single(o => o.ProductId == order.ProductId);
                existedOrder.Amount += order.Amount;
            }
            else
            {
                Orders.Add(order);
            }
        }
    }</order>

Also I advice you to separate your bussiness domain logic from UI. It means the method for adding products should not contain some actions for UI just bussiness logic.
