Data grid title button attributes

Delphi 10.4 + latest Firepower.

Is it possible to change the color of a grid title button.  As a user presses a title button I set that column readonly = false (all other columns readonly = true) so I need to do this to indicate which column is able to be edited.  Another option would be to set and activate an icon to visible on a clicked button but can't seem to find any examples to do any of this.

The app is being built for iOS and uses a style.

Any help would be appreciated.

thanks

  I would use the OnCustomDrawCell event. For instance the following changes the background color to yellow for the buyer column.

   

  procedure TDataGridControlsForm.wwDataGrid1CustomDrawCell(Sender: TObject;
    CellAttributes: TwwCustomDrawCellAttributes);
  begin
    if (cellattributes.DataRow<0) and
      (cellattributes.Column<>nil) and
      (cellattributes.Column.FieldName='Buyer') then
      cellattributes.BackColor:= TAlphaColorRec.Yellow;
  
  end;
