本文介绍了一个用于展示物料清单(BOM)物料详细信息的方法，包括如何从数据服务获取机器模型、物料信息，并将其绑定到UI控件上。通过遍历BOM物料列表，将物料的ERP代码、名称、规格等属性填充到树形列表中，同时递归地添加子物料节点。

    public FrmBOM_MaterialDetails(Bomlist bom) : this()
        {
            var lstMachine = JsonData<List<Machinemodel>>(AppSession.WindowsDataService.GetMachineModels(JsonData(null)));

            lookUpMachineModel.Properties.DataSource = lstMachine;
            lookUpMachineModel.Properties.DisplayMember = "Modelname";
            lookUpMachineModel.Properties.ValueMember = "Id";

            this.txtBomName.Text = bom.BOMName;
            this.lookUpMachineModel.EditValue = bom.MachineModel.Id;
            this.editComments.Text = bom.Comments;

            var lstBomMateial = JsonData<List<BomMaterial>>(AppSession.WindowsDataService.GetMasterBOMMaterial(bom.Id));
            this.BindingColum(typeof(BomMaterial), this.treeList1);
            //this.treeList1.DataSource = lstMateial;
            //this.treeList1.ParentFieldName = "ParentID";
            //this.treeList1.KeyFieldName = "ID";
            if (lstBomMateial == null)
                return;

            foreach (var item in lstBomMateial.ToArray())
            {
                var treeNode = treeList1.Nodes.Add();      //为treeList控件绑定类型
                treeNode.SetValue("ERPCode", item.ERPCode);
                treeNode.SetValue("Material.Materialname", item.Material.Materialname);
                treeNode.SetValue("Specification", item.Specification);
                treeNode.SetValue("Weight", item.Weight);
                treeNode.SetValue("Count", item.Count);
                treeNode.SetValue("Unit", item.Material.MaterialUnit?.UnitName);
                treeNode.SetValue("Comment", item.Comment);
                treeNode.SetValue("Isfixed", item.Isfixed);

                AddBOMChildNode(item.ChildMaterial, treeNode);   //增加子节点
            }
        }
        private void AddBOMChildNode(IList<BomMaterial> lstChilds, TreeListNode node)
        {
            foreach (var item in lstChilds)
            {
                var subNode = node.Nodes.Add();           //为treeList的子节点控件绑定类型
                subNode.SetValue("ERPCode", item.ERPCode);
                subNode.SetValue("Material.Materialname", item.Material.Materialname);
                subNode.SetValue("Specification", item.Specification);
                subNode.SetValue("Weight", item.Weight);
                subNode.SetValue("UseCount", item.Count);
                subNode.SetValue("Unit", item.Material.MaterialUnit?.UnitName);
                subNode.SetValue("Comment", item.Comment);
                subNode.SetValue("IsFixed", item.Isfixed);

                AddBOMChildNode(item.ChildMaterial, subNode);
            }
        }
    }
