NetAdvantage UltraWinTree 绑定(Binding)到类(class),非Datatable数据集成，C#中叫做POCO，领域对象，

UltraWinTree 层次树，表格树，Outlook展示

解决：Re: how to bind WinTree from instance Class

 public class ProductBomTree:Model.ProductBom
    {
        //必须是第一个属性
        public string Part_Name { get; set; }
        public string Part_No { get; set; }
        public List<ProductBomTree> Childrens { get; set; }
    }

 private void button4_Click(object sender, EventArgs e)
        {
            this.ultraTree1.Override.ShowExpansionIndicator = ShowExpansionIndicator.CheckOnDisplay;
            this.ultraTree1.ViewStyle = ViewStyle.OutlookExpress;
            var d = new ProductBomTree { Part_Name="备注1", Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 10, Childrens = new List<ProductBomTree>(){ new ProductBomTree(){ Part_Name="OK1111", Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 3 } }};
            d.Childrens.Add(new ProductBomTree() {Part_Name="OK222", Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 1 });
            var d2 = new ProductBomTree { Part_Name = "备注2", Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 10, Childrens = new List<ProductBomTree>() { new ProductBomTree() { Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 3 } } };
            d2.Childrens.Add(new ProductBomTree() {   Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 2 });
            var d3 = new ProductBomTree { Part_Name = "备注3", Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 10, Childrens = new List<ProductBomTree>() { new ProductBomTree() { Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 3 } } };
            d3.Childrens.Add(new ProductBomTree() { Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 3 });

            var d4 = new ProductBomTree { Part_Name = "备注4", Bom_ID = Guid.NewGuid(), Part_ID = Guid.NewGuid(), Amount = 10, Childrens = null };
            var ds = new List<ProductBomTree>() { d, d2, d3,d4 };
            ultraTree1.DataSource = ds;
}
