        {
            try
            {
                switch (e.KeyCode)
                {
                    case Keys.C:
 
                        if (e.Control == true)
                        {
                            if (FormulaGrid.Selected.Cells.Count == 1)
                            {
                                System.Windows.Forms.Clipboard.SetText(this.FormulaGrid.Selected.Cells[0].Value.ToString());
                            }
                        }
                        break;
