Class: TEgFireGrid
property ShowImageOnEmpty: Boolean default False;
Whether a data cell’s icon is shown when the cell has no text. With
False (the default) an empty cell shows nothing, so an icon
marks only the rows that have a value.
Set it to True for a column made only of icons, for
example a column with no field that shows an action icon on every row
(OnCellImageClick
then tells which row was clicked).
It applies to every column with no ShowImageOnEmpty
of its own.
