Choosing a Column Layout

In a TDBList or TDBCombo display, each column represents a single field of data. For each column, the list needs to know the field name associated with the data, and optionally a heading to be displayed above the data column.

True DBList gets information about field names and headings in one of three ways:

Automatic layouts, derived at run time from the Data control's Recordset (Data control).
Customized layouts, derived at design time from the Data control's Recordset (Data control), and optionally tailored using the control's property pages.
Run-time layouts, created or modified in code by manipulating the Columns collection and its Column object members.
