PrevItem method

Applies To
TQDB, TQDBItem, TQDBView

Declaration
procedure PrevItem;

Description

In TQDB
The PrevItem method moves to the previous item in the list whose key matches the Filter pattern.

A call to PrevItem, when it actually moves to a different item, generates an OnNavigate event. BoF might also be set (see AggressiveUpdate). If ItemIndex already points to the unfiltered first entry PrevItem generates the EQDBOutOfBounds exception or, if a handler for it has been assigned, the WarnOutOfBounds event.

In TQDBItem
As above but also loads the previous item and parses it into fields.

In TQDBView
As above but also displays the previous item in the Panel.
