You define the appearance and behavior of controls in DataWindow objects in the DataWindow painter. By doing that, you specify the controls’ properties. For example, by placing a border around a column, you are setting that column’s Border property.
In most cases, the appearance and behavior of controls is fixed; you do not want them to change at runtime. When you make headings bold, you generally want them to be bold at all times.
In the DataWindow object in Figure 23-1, the Salary Plus Benefits column has a Shadow box border around every data value in the column. To display the border, you set the border property for the column.
