    [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?

   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
