Post subject:  how to highlight current column

Hi Dear Team,
Good day.
Is there a way to highlight current column title when the current cell is moving around the DBGridEh?
My use case is: Too many columns in the grid, the user couldn't easily find which column he is working on.
Thanks.

Hello

Yes, you can.
Use TDBGridEh.OnGetTitleParams event like this.

Code:
procedure TForm1.FormCreate(Sender: TObject);
begin
  DBGridEh1.TitleParams.FillStyle := cfstGradientEh;
end;

procedure TForm1.DBGridEh1ColEnter(Sender: TObject);
begin
  DBGridEh1.InvalidateTitle;
end;

procedure TForm1.DBGridEh1GetTitleParams(Grid: TCustomDBGridEh;
  Params: TDBGridDrawTitleCellParamsEh);
begin
  if (Params.Column.Index = DBGridEh1.SelectedIndex) then
  begin
    Params.Color := clWebOrange;
  end;
end;

Is it possible to do this in the EhLib source code so you don't have to repeat this encoding every time you need it? Because I tried to implement and it didn't work
