Winform让DataGridView左侧显示图片

效果图片

重写DataGridView的OnRowPostPaint方法或者直接在DataGridView的RowPostPaint事件里写，如下(重写DataGridView的OnRowPostPaint方法)

using System;
using System.Text;
using System.Windows.Forms;
using System.Drawing;
namespace Test
{
 class DataGridViewEx : DataGridView
 {
   SolidBrush solidBrush;
   public DataGridViewEx()
   {
     solidBrush = new SolidBrush(this.RowHeadersDefaultCellStyle.ForeColor);
   }

protected override void OnRowPostPaint(DataGridViewRowPostPaintEventArgs e)
   {
     e.Graphics.DrawImage(Image对象, e.RowBounds.Location.X, e.RowBounds.Location.Y); base.OnRowPostPaint(e);
   }
 }
}
