{
    public override void OnPaint(CellDrawingContext dc)
    {
        dc.DrawCellBackground();
        var bounds = GetBodyBounds();
        var color = Cell?.Data is "OK" ? SolidColor.Green : SolidColor.Red;
        dc.Graphics.FillRectangle(
            new Rectangle(bounds.X + 2, bounds.Y + 2, 12, bounds.Height - 4), color);
        dc.DrawCellText();
