DataGridView特殊按鈕（DisableButtonColumn）

實現的效果如下圖，點擊一次按鈕之後，按鈕不可再點擊：

主要代碼如下：

        private void AddButtonColumn()
        {
            DataGridViewDisableButtonColumn column1 = new DataGridViewDisableButtonColumn();
            column1.Name = "allowinpacuButton";
            column1.HeaderText = "";
            column1.DefaultCellStyle.NullValue = "批准";
            dataGridView_pacuRecord.Columns.Add(column1);
        }

    public class DataGridViewDisableButtonColumn : DataGridViewButtonColumn
    {
        public DataGridViewDisableButtonColumn()
        {
            this.CellTemplate = new DataGridViewDisableButtonCell();
        }
    }

    public class DataGridViewDisableButtonCell : DataGridViewButtonCell
    {
        private bool enabledValue;
        public bool Enabled
        {
            get
            {
                return enabledValue;
            }
            set
            {
                enabledValue = value;
            }
        }

        // Override the Clone method so that the Enabled property is copied.
        public override object Clone()
        {
            DataGridViewDisableButtonCell cell =
                (DataGridViewDisableButtonCell)base.Clone();
            cell.Enabled = this.Enabled;
            return cell;
        }

        // By default, enable the button cell.
        public DataGridViewDisableButtonCell()
        {
            this.enabledValue = true;
        }

        protected override void Paint(Graphics graphics,
            Rectangle clipBounds, Rectangle cellBounds, int rowIndex,
            DataGridViewElementStates elementState, object value,
            object formattedValue, string errorText,
            DataGridViewCellStyle cellStyle,
            DataGridViewAdvancedBorderStyle advancedBorderStyle,
            DataGridViewPaintParts paintParts)
        {
            // The button cell is disabled, so paint the border,  
            // background, and disabled button for the cell.
            if (!this.enabledValue)
            {
                // Draw the cell background, if specified.
                if ((paintParts & DataGridViewPaintParts.Background) ==
                    DataGridViewPaintParts.Background)
                {
                    SolidBrush cellBackground =
                        new SolidBrush(cellStyle.BackColor);
                    graphics.FillRectangle(cellBackground, cellBounds);

                }

                if ((paintParts & DataGridViewPaintParts.Border) ==

                        advancedBorderStyle);
                }

                // Calculate the area in which to draw the button.
                Rectangle buttonArea = cellBounds;
                Rectangle buttonAdjustment =
                    this.BorderWidths(advancedBorderStyle);

                    cellStyle, advancedBorderStyle, paintParts);
