{
    if (e.ColumnIndex == 性别列编号)
    {
        e.Value = (int)e.Value > 0 ? "男" : "女";
        e.FormattingApplied = true;
    }
}

Answer 1

private void dgvPatientDocInfo_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
        {
            DataGridViewRow row = this.dgvPatientDocInfo.Rows[e.RowIndex];
            if (e.ColumnIndex == 2)
           {
                if (row != null)
                {
                   e.value=row.Cells["sex"].Value.ToString()=="1"?"男":"女";
}
}
}

Answer 2

CellFormatting 总是触发呢，怎么办，改了的值一会儿就给变回去了！
