DataGridView中设置列高自动调整

private void dgvParent_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
        {
            this.dgvParent.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader; //根据数据内容自动调整列宽
            this.dgvParent.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCellsExceptHeaders; //根据数据内容自动调整行高
        }
