一、绑定DataSet
1. 创建数据源 DataSet;DataSet中有两张表,并且主表与子表必须建立关联;
DataTable dtMaster =new DataTable(); DataTable dtDetail= new DataTable(); dtMaster .Columns.Add("RelationColumn"); dtDetail.Coumns.Add("RelationColumn"); using (DataSet ds = new DataSet()) { ds.Tables.AddRange(new DataTable[] { dtMaster .Copy(), dtDetail.Copy() }); // 创建表关系 DataRelation relation = new DataRelation("detailTable", ds.Tables[0].Columns[0], ds.Tables[1].Columns[0], false); ds.Relations.Add(relation); // 添加 gridControl1.DataSource = ds.Tables[0]; // 指定数据源 }
2. ui 设置 gridControl 控件;
gridControl中已有一默认的Gridview1 为MainView 用来显示dtMaster的数据;
gridControl 添加一个level.在该level中创建 gridView 命名为gvDetial. 用来显示dtDetail的数据;
修改level的名称,名称必须和数据源中定义的DataRelation的名称一致;gridcontrol 会根据MasterTable的relation来创建并显示detail的数据结构;
将两个Gridveiw中的添加Column ,并绑定相应数据源表的字段;
1 this.gvTable.OptionsDetail.AllowExpandEmptyDetails = true; 2 this.gvTable.OptionsDetail.ShowDetailTabs = false; 3 this.gvTable.OptionsPrint.ExpandAllDetails = true; 4 this.gvTable.OptionsPrint.PrintDetails = true;
二、绑定实体对象
[DataContract] [Serializable] public class PlanInfo:C_ProductPlan { public PlanInfo() { Items = new List<ProducePlanItem>(); } [DataMember] public List<ProducePlanItem> Items { get; set; } } [DataContract] [Serializable] public class ProducePlanItem :C_ProductPlanItem { public ProducePlanItem() { ProcessConfig = new List<ProcessInfo>(); } [DataMember] public List<ProcessInfo> ProcessConfig { get; set; } } [Serializable] public class ProcessInfo { public String Name{get;set;} public int Order{get;set;} public bool? IsChecked{get;set;} public String Memo{get;set;} }
public class ProducePlanItems : ArrayList, IRelationList { public ProducePlanItems() { } #region IRelationList 成员 public System.Collections.IList GetDetailList(int index, int relationIndex) { return this[index].ProcessConfig; } public string GetRelationName(int index, int relationIndex) { return "ProcessConfig"; } public bool IsMasterRowEmpty(int index, int relationIndex) { return false; } public int RelationCount { get { return 1; } } #endregion public virtual new ProducePlanItem this[int index] { get { return base[index] as ProducePlanItem; } } }
需要引用Dexexpress.Data.dll,
1.gridview-MainView 绑定到UI中定义的ProducePlanItems.
2.添加一个level1 将level1重命名称ProcessConfig(对应上面IRelationList.GetRelationName的返回
3.level1 添加 gridview2 ,需要手动设置gridview的列,可以设置gridview2的ViewCaption
4.获取数据后将items转化成producePlanItems,并绑定到UI
