| The Basics > Specifying a Data Source > What is Application Mode? |
If you prefer to work with standard Visual Basic arrays, application mode is recommended, as it is well-suited to array manipulation. To use application mode, set the DataMode property of a TDBList or TDBCombo control to 3 - Application at design time. At a minimum, you will need to write code to handle two events: ClassicRead and UnboundGetRelativeBookmark. The former is fired whenever the list requests a value to be displayed in a particular cell; the latter is fired whenever the list needs to determine the bookmark used to identify a particular row.
