C# datagridView 表格渲染变色 ( 动态改变表格值) 绘制时改变表格值

private void DGV_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
        {

            if (e.ColumnIndex >= 0 && DGV.Columns[e.ColumnIndex].Name == "字段名称")
            {
                if (Collections.Entity.to_double(e.Value) > 0)
                {
                    e.CellStyle.BackColor = Color.Red;
                }
                else
                { }
            }
          

        }

这个方法好像更好一些
