A good morning to you all.

I have a string grid, with data in it.
Has 6 rows and 3 colums. Want I need to be able to do is color the colum that has the selected cell. So, If the click on a cell in coloum 2 that whole colums color becomes dark blue. Or if they selected a cell in coloum 1 that whole colums color would go dark blue.

Basically, it's getting the selected cells coloum and using that on the ondraw event - shouldn't be to hard :)

I assume that you've 1 fixed row and no fixed col...

var
  Form1: TForm1;
  BlueCol: Integer;
implementation

{$R *.dfm}

procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
  Rect: TRect; State: TGridDrawState);
begin
If (ACOl=BlueCOl) and (ARow > 0) then
   StringGrid1.Canvas.Brush.Color := clNavy
else
   StringGrid1.Canvas.Brush.Color := clWIndow ;
   StringGrid1.Canvas.FillRect(Rect);
end;

procedure TForm1.StringGrid1SelectCell(Sender: TObject; ACol,
  ARow: Integer; var CanSelect: Boolean);
begin
   BlueCOl := ACol;
   STringGrid1.Refresh;
end;

Ohh one thing (if u got a sec)
Can I make it so when I click say, a button I can select a row in a certain cell in the string grid?
Ie, click button and on the string grid it selects stringgrid.cells[0,2]
Thought there would be a way to call stringgrid.select[0,2] but alas there isnt. If its a quick 5 seconds then sweet. Otherwise I will create a new question :)

Cheers

What about calling

Procedure TForm1.Button1CLick(Sender: TObject);
begin
   STringGrid1.Col := 0;
   StringGrid1.Row := 2;
end;
