DBGrid1.Columns[1].Font.Color

[Henry Olive 5]

Good Day,

My table looks like below (In a DBGrid)

CODE

-------

AAA

AAA-AA

AAA-AA-BB

BBB

BBB-BB

BBB-BB-CC

 

I want to make font color ClRed  if the Value.Length <= 3

That is  just AAA and BBB value's font.color should be red

 

procedure TAccAccounts.DBGrid1DrawColumnCell(Sender: TObject; const Rect: TRect;
  DataCol: Integer; Column: TColumn; State: TGridDrawState);
  var
  Str : String;
begin
  Str := DBGrid1.Columns[0].Field.Value;
  if Length(Str) <= 3 then
     DBGrid1.Columns[0].Font.Color := ClRed else
     DBGrid1.Columns[0].Font.Color := ClWindowText;
   Self.Canvas.FillRect(Rect);
end;

 

Eventhough Delphi makes AAA clRed but doesnt make BBB clRed it is still clBlack

Thank You

Have you tried using the debugger to inspect the actual content of Str in the problematic case?

In the event you should change the color of the font on canvas not the column.

sure what... this:

 

procedure TForm1.DBGrid1DrawDataCell(Sender: TObject; const Rect: TRect; Field: TField; State: TGridDrawState);
begin
  if Field.AsString.trim.Length <= 3 then
    DBGrid1.Canvas.Font.Color := clRed
  else
    DBGrid1.Canvas.Font.Color := clBlue;

  DBGrid1.DefaultDrawColumnCell(Rect, 0, DBGrid1.Columns[0] , State);
end;
