Class: TEgFireGridColumn
property PickList: TStrings;Values the editor of a text or number cell offers in a drop-down
list, as the VCL grid’s Column.PickList. Empty (the
default) means no list.
With a list, the edit box has a button that opens it (Alt+Down does
too); choosing an item writes it and ends the edit. The text can still
be typed freely, unless PickListOnly
is True. The list is not used by memo, lookup, check box or
picture columns, nor for a value that has line breaks.
