C#对XtraGrid控件实现主从表关系绑定

1、准备源数据。

/// <summary>
/// 记录基础信息
/// </summary>
public class DetailInfo
{
    public DetailInfo()
    {
        this.ID = Guid.NewGuid().ToString();
    }

    /// <summary>
    /// ID标识
    /// </summary>
    public string ID { get; set; }

    /// <summary>
    /// 名称
    /// </summary>
    public string Name { get; set; }

    /// <summary>
    /// 描述信息
    /// </summary>
    public string Description { get; set; }
}

/// <summary>
/// 二级层次的列表
/// </summary>
public class Detail2Result : DetailInfo
{
    public List<DetailInfo> Detail2List { get; set; }
}

2、绑定数据源

/// <summary>
/// 绑定数据源
/// </summary>
private void BindData()
{
    //创建测试数据
    var result1 = new Detail2Result()
    {
        Name = "测试1",
        Description = "描述内容",
        Detail2List = new List<DetailInfo>()
        {
            new DetailInfo()
            {
                Name = "111测试",
                Description = "111描述内容"
            },
            new DetailInfo()
            {
                Name = "222测试",
                Description = "222描述内容"
            },
            new DetailInfo()
            {
                Name = "333测试",
                Description = "333描述内容"
            }
        }
    };

    var result2 = new Detail2Result()
    {
        Name = "测试2",
        Description = "描述内容",
        Detail2List = new List<DetailInfo>()
        {
            new DetailInfo()
            {
                Name = "111测试",
                Description = "111描述内容"
            },
            new DetailInfo()
            {
                Name = "222测试",
                Description = "222描述内容"
            },
            new DetailInfo()
            {
                Name = "333测试",
                Description = "333描述内容"
            }
        }
    };

    //构造一个记录的集合
    var list = new List<Detail2Result>() { result1, result2 };

    //绑定数据源
    this.gridControl.DataSource = list;
}

3、DevExpress的GridControl控件的设置

在主视图下添加一层视图为gridView2,并修改当前视图的 Change LeveName 为Detail2List (如果不修改结果是数据绑定失败)

设置gridView2属性中的ViewCaption 属性。

4、效果

5、子表格获取行数据

DevExpress.XtraGrid.Views.Grid.GridView currentView = (DevExpress.XtraGrid.Views.Grid.GridView)this.gridControl.FocusedView;
DetailInfo focusRow = currentView.GetFocusedRow() as DetailInfo; //用在事件中：currentView.GetRow(e.RowHandle) as DetailInfo;
XtraMessageBox.Show(focusRow.Name);
