新功能介绍

Introduction to new functions

在PN码library界面增加了PN码多选功能，方便通过批量勾选进行删除操作，本来不想做这么琐碎的功能，结果自己用到这里发现没有还真不行。因为是PN码一般是批量生成，一错就是N个编码一起，一个一个地删除真是麻烦死了。这个复选框效果看着很简单，做起来细节非常多，你要做全乎了，还得把全选那个按钮做上，可真不是一般的麻烦，为此我还得专门自己写个复选框控件DataGridViewDisableCheckBoxCell（当然也是在网上大神的开源控件的基础上魔改的）

关于DataGridViewDisableCheckBoxCell

自己魔改的一个开源checkbox控件，专门放在datagridview的行里作为行控件使用，包括head行用的也是这个，利用.net开发的优势，可以做各种复杂的控件效果。DataGridViewDisableCheckBoxCell控件的代码直接分享：

public class DataGridViewDisableCheckBoxCell : DataGridViewCheckBoxCell
{

    private bool enabledValue;
    /// <summary>  
    /// This property decides whether the checkbox should be shown checked or unchecked.  
    /// </summary>  
    public bool Enabled
    {
        get
        {
            return enabledValue;
        }
        set
        {
            enabledValue = value;
        }
    }
    /// Override the Clone method so that the Enabled property is copied.  
    public override object Clone()
    {
        DataGridViewDisableCheckBoxCell cell =
            (DataGridViewDisableCheckBoxCell)base.Clone();
        cell.Enabled = this.Enabled;
        return cell;
    }


    public DataGridViewDisableCheckBoxCell()
    {
        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 checkBox cell is disabled, so paint the border,  
        // background, and disabled checkBox 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);
                cellBackground.Dispose();
            }

            // Draw the cell borders, if specified.
            if ((paintParts & DataGridViewPaintParts.Border) ==
                DataGridViewPaintParts.Border)
            {
                PaintBorder(graphics, clipBounds, cellBounds, cellStyle,
                    advancedBorderStyle);
            }

            // Calculate the area in which to draw the checkBox.
            CheckBoxState state = value.ToString() != "0" && (bool)value ?
                CheckBoxState.CheckedDisabled : CheckBoxState.UncheckedDisabled;
            Size size = CheckBoxRenderer.GetGlyphSize(graphics, state);
            Point center = new Point(cellBounds.X, cellBounds.Y);
            center.X += (cellBounds.Width - size.Width) / 2;
            center.Y += (cellBounds.Height - size.Height) / 2;

            // Draw the disabled checkBox.
            CheckBoxRenderer.DrawCheckBox(graphics, center, state);
        }
        else
        {
            // The checkBox cell is enabled, so let the base class 
            // handle the painting.
            base.Paint(graphics, clipBounds, cellBounds, rowIndex,
                elementState, value, formattedValue, errorText,
                cellStyle, advancedBorderStyle, paintParts);
        }
    }
}
