XtraGrid控件-----List数据源实现主从表关系绑定
一、实现方式
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);
