datagridView的数据列绑定问题

单元格格式化数据
private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    if (e.ColumnIndex == 1 /*status列的Index*/)
    {
        if (object.Equals(e.Value, 0))
        {
            e.Value = "未完成";
            e.CellStyle.ForeColor = Color.Red;
        }
        else
        {
            e.Value = "已完成";
            e.CellStyle.ForeColor = Color.Green;
        }
    }
}

 

行数据格式化数据，一行的单元格数据可以根据另一个单元值而定

 

private void dataGridView1_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)
        {

                int rowsindex=e.RowIndex ;
                int row_count=dataGridView1 .Rows.Count ;
                if (rowsindex < row_count - 1)
                {

                    DataGridViewRow dgr = dataGridView1.Rows[e.RowIndex];
                    try
                    {
                        dgr.Cells["name_values"].Value = dgr.Cells["Column0"].Value.ToString();
                        //dgr.DefaultCellStyle.ForeColor = 设置的颜色;                       
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                    }
                }

        }
