Class: TEgDBGridEx
property ShowImageOnEmpty: Boolean default True;Whether a column’s data-cell ImageIndex icon (not the
field’s own graphic/BLOB content) still shows when the cell’s content is
empty. True (the default) preserves this unit’s original
behavior - the icon always showed, regardless of text.
“Empty” means the field is null or CellText = '', except
for a graphic/BLOB column, which checks only whether the field itself is
null, since its CellText is normally blank anyway (the real
image fills that space instead).
Overridable per column - see TEgColumn.ShowImageOnEmpty.
