Setting the scene for writing a new inner class

  • Create a new UIController called "ShowOrdersToDemoInnerClasses"
  • Use the Orders Table
  • Add the following local columns to collect the order statistics
  • Design the screen so that you'll have some columns on the grid, and the 3 local columns below the grid.
public class ShowOrdersToDemoInnerClasses : UIControllerBase
{

    public readonly Models.Orders Orders = new Models.Orders();
    public readonly NumberColumn Items = new NumberColumn("Items", "2");
    public readonly NumberColumn TotalQuantity = new NumberColumn("Total Quantity", "4");
    public readonly NumberColumn TotalAmount = new NumberColumn("Total Amount", "5C");
    public ShowOrdersToDemoInnerClasses()
    {
        From = Orders;
    }
    public void Run()
    {
        Execute();
    }
    protected override void OnLoad()
    {
        View = () => new Views.ShowOrdersToDemoInnerClassesView(this);
    }
}
