Prepare the view for a general use

Let's modify our view code so any controller can use it. First let's create an AddColumns method that receives an array of columns and calls the AddColumn method for each column:

partial class ShowView : Shared.Theme.Controls.Form
{
-   ShowCustomers _controller;
-   public ShowView(ShowCustomers controller)
    public ShowView()
    {
-       _controller = controller;
        InitializeComponent();
-       foreach (var col in _controller.Customers.Columns)
-       {
-          AddColumn(col);
-       }
    }
    public void AddColumns(prams ColumnBase [] columns)
    {
        foreach (var col in columns)
        {
            AddColumn(col);
        }
    }

} 

Now we need to modify the controller's code, so it would use this view and the AddColumns method:

    protected override void OnLoad()
    {
-       View = () => new Views.ShowView(this);
        View = () =>
        {
            var view = new Views.ShowView();
            view.AddColumns(Customers.CustomerID, Customers.Address, Customers.City, Customers.Phone);
            return view;
        };   
} 

The result will look like this:

As we did in the previous example, you can use the foreach loop to add all the columns.

So now, adding a new controller with no view, that will use our existing view in the same manner, is easy. The next article will show it.
