            //fpSpread1.StartAnnotationMode();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            fpSpread1.StopAnnotationMode();
        }

        private void fpSpread1_AnnotationModeStarting(object sender, FarPoint.Win.Spread.AnnotationModeEventArgs e)
        {
            
            e.DrawingSurface.ForeColor = Color.BlueViolet;
            e.DrawingSurface.BackColor = Color.Thistle;
        }
