UserMethods class

In this page we'll

• introduce the ENV.UserMethods class - used by the u member
• u is a member of the base classes we use from ENV and that is how we can access it through out our code
• We'll show how it has any function that you knew in magic with it's source code
• We'll explain that it serves 3 roles:
  • You're always productive - You'll never be stuck, you can always think, "How would I have done that in magic" and start from there
  • You can read it's code and learn how to "do it in .NET"
  • New .NET Developers can learn from it the subtleties in your application (Like Date.Empty etc...)

protected override void OnSavingRow()
{
-    if (Orders.OrderDate.Year < 1990)
     if (u.Year( Orders.OrderDate) < 1990)
    {
        Message.ShowError("Invalid Year");
    }
}
