using ENV.Data;
using System.Diagnostics;

namespace Northwind.Exercises.SelectionList

    public class SelectCustomers : UIControllerBase
    {

        public readonly Models.Customers Customers = new Models.Customers();
        internal TextColumn _CustomerID = new TextColumn();

        public SelectCustomers()
        {
            From = Customers;
        }

        public void Run(TextColumn customerId)
        {
            _CustomerID = customerId;
            Execute();
        }

        protected override void OnLoad()
        {
            Activity = Activities.Browse;
            AllowDelete = false;
            AllowInsert = false;
            AllowUpdate = false;
            AllowSelect = true;
            View = () => new Views.SelectCustomersView(this);
        }
        protected override void OnSavingRow()
        {
-            Debug.WriteLine("Selecting Customer ID" + Customers.CustomerID);
             _CustomerID.Value = Customers.CustomerID;
        }
