It is possible to have rows with varying heights? I know about the RowHeightPercent property. I have a scenario where some rows should be "single row height" (RowHeightPercent 100), some double height (200), and others triple height (300). I don't think I want higher than 300 for any given row.

Thanks

  Unfortunately this is not supported. You can use cell hints if you wish for the user to move the mouse over a cell and show its contents (dgShowCellHint) in conjunction with using OnCreateHintWindow.

   

  procedure TGridHintIniDemo.wwDBGrid1CreateHintWindow(Sender: TObject;
    HintWindow: TwwGridHintWindow; AField: TField; R: TRect;
    var WordWrap: Boolean; var MaxWidth, MaxHeight: Integer;
    var DoDefault: Boolean);
  begin
    WordWrap := True;
    if (AField is TBlobField) then
       MaxWidth := 100;
    MaxHeight := Screen.Height;
  end;

  The user can also resize the rows himself using dgRowResize.
