  • GridView列添加下拉框,绑定数据源并设置默认值

    添加下拉框:

    DataGridViewComboBoxColumn dataGridViewComboBoxColumn = new DataGridViewComboBoxColumn();
    dataGridViewComboBoxColumn.Name = "dgvcbcSeatType";
    dataGridViewComboBoxColumn.DataPropertyName = "SeatType";
    dataGridViewComboBoxColumn.DataSource = this.getSeatTypies();
    dataGridViewComboBoxColumn.ValueMember = "key";
    dataGridViewComboBoxColumn.DisplayMember = "value";
    dataGridViewComboBoxColumn.HeaderText = "席别";
    dataGridViewComboBoxColumn.Width = 100;
    this.dgvOrder.Columns.Add(dataGridViewComboBoxColumn);
    
    数据源:
            private List<KeyValuePair<string, string>> getSeatTypies()
            {
                return new List<KeyValuePair<string, string>>
                {
                    new KeyValuePair<string, string>("-1", "无座"),
                    new KeyValuePair<string, string>("1", "硬座"),
                    new KeyValuePair<string, string>("2", "软座"),
                    new KeyValuePair<string, string>("3", "硬卧"),
                    new KeyValuePair<string, string>("4", "软卧"),
                    new KeyValuePair<string, string>("6", "高级软卧"),
                    new KeyValuePair<string, string>("9", "商务座"),
                    new KeyValuePair<string, string>("7", "一等软座"),
                    new KeyValuePair<string, string>("8", "二等软座"),
                    new KeyValuePair<string, string>("M", "一等座"),
                    new KeyValuePair<string, string>("O", "二等座"),
                    new KeyValuePair<string, string>("P", "特等座")
                };
            }

    默认值只能在界面初始化直接中设置
