For this tutorial, and as an example to refer to throughout this documentation, we’ll create a grid with Invoice information.

First of all we need to decide what data we want to represent at the client. Let’s have the following:

• Invid – the invoice number,
  
• invdate – the date of the invoice,
  
• amount,
  
• tax,
  
• total (including tax), and
  
• note – additional information about the invoice.
