Question

DBGrid Row Colors

Asked by: stevenorris

I would like to take a DBGrid and color every ODD row a separate color.  The Even rows should remain white.  My problem is the ROW property is not published and I know of no other way.  Does anyone have any ideas on getting this accomplished.  Thanks in advance.

hi stevenorris;

try this, on the event OnDrawColumnCell

      procedure TForm1.DBGrid1DrawColumnCell(Sender: TObject; const Rect:  Trect;
        DataCol: Integer; Column: TColumn; State: TGridDrawState);
      var Color : TColor;
      begin
        if not(gdSelected in state) then
        begin
          if (Table1.RecNo mod 2)=1 then
            Color := RGB(224, 231, 223)   //a color
          else
            Color := RGB(254, 255, 239); //another color
          Dbgrid1.Canvas.Brush.Color := Color;
          Dbgrid1.Canvas.FillRect(Rect);
        end;
        dbGrid1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
      end;

This will do exactly what you require:
-Rob.


procedure TForm1.DBGrid1DrawColumnCell(Sender: TObject; const Rect: TRect;
  DataCol: Integer; Column: TColumn; State: TGridDrawState);
begin
//  Memo1.Lines.Add(inttostr(Rect.Top));  I used this to determine column height (= 18)
  if Rect.Top mod 36 = 0 then
  begin
    DBGrid1.Canvas.Brush.color := clred;
    DBGrid1.Canvas.FillRect(Rect);
  end;
  DBGrid1.Canvas.TextOut(Rect.Left+3,Rect.Top+3,DBGrid1.Fields[Datacol].Value);
end;

Meikl.. I don't see rows highlited...

hi again rob, :-)

>Meikl.. I don't see rows highlited...
? what does you mean with highlited ?

meikl

 

by: RBertoraPosted on 1999-09-03 at 11:40:39ID: 2021755

Highlited -> every odd row is not coloured....


this line of yours:

if (Table1.RecNo mod 2)=1 then

does it do what it supposed to ?

Rob. -I just don't get the results I expected using your code... but perhaps this is due to delphi versions etc.. I am using D4.

hi kenny, hi rob,
>if (Table1.RecNo mod 2)=1 then
>does it do what it supposed to ?
only for paradox-tables :-(

well, a little change and should work now on all linked databases

procedure TForm1.DBGrid1DrawColumnCell(Sender: TObject; const Rect: TRect;
  DataCol: Integer; Column: TColumn; State: TGridDrawState);
var Color : TColor;
begin
  if not(gdSelected in state) then
  begin
    if (dbgrid1.MouseCoord(Rect.Left,Rect.Top).y mod 2)=1 then
      Color := RGB(224, 231, 223)
    else
      Color := RGB(254, 255, 239);
    Dbgrid1.Canvas.Brush.Color := Color;
    Dbgrid1.Canvas.FillRect(Rect);
  end;
  dbGrid1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
end;

tested with d3. but should work for d4 also.

Hello All,

I have tried each example and I have the following:

procedure TForm1.DBGrid1DrawColumnCell(Sender: TObject; const Rect: TRect;
  DataCol: Integer; Column: TColumn; State: TGridDrawState);
begin
   if not (gdSelected in state) then begin
      if Rect.Top mod 36 = 0 then begin
         DBGrid1.Canvas.Brush.Color := RGB(192,220,192);
         DBGrid1.Canvas.FillRect(Rect);
      end;
      DBGrid1.DefaultDrawColumnCell(Rect,DataCol,Column,State);
   end;
end;


It seems to work fine with the tables I'm using (Codebase).  Thanks to all for the information, I have been asking this question for about a month on several news groups.  Thanks again.

Steve
