Is there a way to get the column header check box to check all of the rows that are displayed when the grid is in a filtered state using narrow down filtering? If I load 20 rows, filter it down to 5 and then check the header box, it checks 5 boxes, but not necessarily the ones that are displayed.
with AdvStringGrid1 do
begin
ControlLook.NoDisabledCheckRadioLook := True;
Options := Options + [goEditing];
ShowSelection := False;
ColCount := 4;
FixedCols := 1;
FixedColWidth := 22;
RowCount := 2;
FixedRows := 1;
ColWidths[1] := 14;
ColWidths[2] := 150;
ColWidths[3] := 600;
AddCheckBoxColumn(1);
AddCheckBox(1,0,false,false);
MouseActions.CheckAllCheck := True;
end;
