What is the best way to reuse pages from one website in another?

public class SomePresenter
{
    public ISomeView View{get; set;}

    public void InitializeView()
    {
        //Setup all the stuff on the view the first time

        View.Name = //Load from database
        View.Orders = //Load from database
    }

    public void LoadView()
    {
        //Handle all the stuff that happens each time the view loads
    }

    public Int32 AddOrder(Order newOrder)
    {
        //Code to update orders and then update the view
    }
}

public interface ISomeView
{
    String Name {get; set;}
    IList<Order> Orders{get; set;}
}

public partial class SomeConcreteView : System.Web.UI.Page, ISomeView
{
    public SomePresenter Presenter{get; set;}

    public SomeConcreteView()
    {
        Presenter = new SomePresenter();

        //Use the current page as the view instance
        Presenter.View = this;
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if(!IsPostBack)
        {
            Presenter.InitializeView();
        }

        Presenter.LoadView();
    }

    //Implement your members to bind to actual UI elements
    public String Name
    {
        get{ return lblName.Text; }
        set{ lblName.Text = value; }
    }

    public IList<Order> Orders
    {
        get{ return (IList<Order>)ordersGrid.DataSource; }
        set
        {
            ordersGrid.DataSource = value;
            ordersGrid.DataBind();
        }
    }

    //Respond to UI events and forward them to the presenter
    protected virtual void addOrderButton_OnClick(object sender, EventArgs e)
    {
        Order newOrder = //Get order from UI
        Presenter.AddOrder(newOrder);
    }
}
