重绘DataGridView的DataGridViewCheckBoxCell控件

最近项目中要用到在DataGridView单元格里面放置一个带有文本的 DataGridViewCheckBoxCell控件但原有

的是不支持的然后我就想着重写个 DataGridViewCheckBoxTextCell
下面是源码：(如有疑问可以加源码分享群 81582487 来问我)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Windows.Forms.VisualStyles;
using System.Drawing;

namespace WindowsDemo
{
public class DataGridViewCheckBoxTestCell : DataGridViewCheckBoxCell
{

public DataGridViewCheckBoxTestCell()
: base()
{

}

public CheckBoxState CheckBoxTestState { get; set; }
        /// <summary>
        /// 单元格边框颜色
        /// </summary>
        private Color CellBorderColor { get { return Color.FromArgb(172, 168, 153); } }

protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle

cellBounds, int rowIndex, DataGridViewElementStates cellState, object value, object

formattedValue, string errorText, DataGridViewCellStyle cellStyle,

DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts)
        {
            var check = (Boolean)value;
            CheckBoxTestState = check ? CheckBoxState.CheckedNormal :

CheckBoxState.UncheckedNormal;
if (paintParts == DataGridViewPaintParts.Background || paintParts ==

DataGridViewPaintParts.All)
            {
                graphics.FillRectangle(new SolidBrush(cellStyle.BackColor), cellBounds);
            }
            if (paintParts == DataGridViewPaintParts.Border || paintParts ==

DataGridViewPaintParts.All)
            {
                graphics.DrawRectangle(new Pen(CellBorderColor), cellBounds);
            }
            if (paintParts == DataGridViewPaintParts.SelectionBackground || Selected)
            {
                graphics.FillRectangle(new SolidBrush(cellStyle.SelectionBackColor),

cellBounds);
            }
            var col = OwningColumn as DataGridViewCheckBoxTextColumn;
            if (col != null && !string.IsNullOrEmpty(col.Text))
            {
                graphics.DrawString(col.Text, cellStyle.Font, new SolidBrush(Selected ?
                    cellStyle.SelectionForeColor : cellStyle.ForeColor),
                    new Point(cellBounds.X + 25, cellBounds.Y + cellBounds.Height / 4));
            }
            if (!string.IsNullOrEmpty(Text))
            {
                graphics.DrawString(Text, cellStyle.Font, new SolidBrush(Selected ?
                  cellStyle.SelectionForeColor : cellStyle.ForeColor),
                  new Point(cellBounds.X + 25, cellBounds.Y + cellBounds.Height / 4));
            }
            CheckBoxRenderer.DrawCheckBox(graphics, new Point(cellBounds.X + 4, cellBounds.Y +

cellBounds.Height / 4), CheckBoxTestState);
// ButtonRenderer.DrawButton(graphics, new Rectangle(new Point(cellBounds.X + 50,

cellBounds.Y + cellBounds.Height / 4), new Size(20, 20)), true, PushButtonState.Default);
// base.Paint(graphics, clipBounds, cellBounds, rowIndex, cellState, value,

formattedValue, errorText, cellStyle, advancedBorderStyle, paintParts);
}

protected override void OnMouseDown(DataGridViewCellMouseEventArgs e)
        {
            var check = (bool)Value;
            CheckBoxTestState = check ? CheckBoxState.CheckedNormal :

CheckBoxState.UncheckedNormal;
            Value = !check;
            base.OnMouseDown(e);
        }

public string Text { get; set; }

}
}

使用也很简单：（使用时先把结构加载完了在对这列进行如下操作）
DataGridViewCheckBoxTestCell check3 = new DataGridViewCheckBoxTestCell();
            check3.Text = "请选择";
            check3.Value = true;
            row.Cells["check"] = check3;
