本方法主要实现检验单上二开增加下拉列表绑定使用决策枚举值时，如何与使用决策表体使用决策可选择项一致，即根据业务类型来区分，本例以在检验项目表体增加下拉列表为例：

1、检验单检验项目表体增加下拉列表类型字段，绑定使用决策枚举；

2、二开表单插件继承BaseControlEdit，挂在检验单表单插件列表的最后；

3、二开示例代码如下：

using Kingdee.BOS.Core.Metadata.FieldElement;

using Kingdee.BOS.Core.SqlBuilder;

using Kingdee.K3.Core.MFG;

using Kingdee.BOS.Core.Metadata;

using Kingdee.BOS.Orm.DataEntity;

using Kingdee.BOS.ServiceHelper;

using Kingdee.K3.Core.MFG.EntityHelper;

using Kingdee.BOS;

using Kingdee.BOS.Core.DynamicForm.PlugIn.ControlModel;

namespace Kingdee.K3.MFG.QM.Business.PlugIn.Bill

{

    public class test : BaseControlEdit

    {

        public override void EntityRowClick(BOS.Core.DynamicForm.PlugIn.Args.EntityRowClickEventArgs e)

        {

            base.EntityRowClick(e);

            switch (e.Key.ToUpperInvariant())

            {

                case "FITEMDETAIL"://此处为增加的二开下拉列表字段所在的单据体标识大写形式

                    string businessType = this.View.Model.GetValue<string>(CONST_QM_InspectBill.CONST_FBillHead.KEY_FBusinessType);

                    this.setOtherPolicyItemsByBusType(businessType,e.Row);

                    break;

            }

        }

/// <summary>

        /// 根据业务类型获取使用决策

        /// </summary>

        /// <param name="businessTypeId"></param>

        private void setOtherPolicyItemsByBusType(string businessTypeId, int row)

        {

            //使用策略处理

            ComboField useItemField = this.View.BusinessInfo.GetField("FTestPolicy") as ComboField;//此处为二开增加的枚举下拉列表字段的标识

            DynamicObject useItemFieldObj = useItemField.EnumObject;

            IEnumerable<DynamicObject> items = useItemFieldObj.GetDynamicValue<DynamicObjectCollection>("Items") .OrderBy(g => g.GetDynamicValue<int>("Seq")).ToList();

            List<DynamicObject> useItems = new List<DynamicObject>();

            //获取汇总模型预插

            QueryBuilderParemeter param = new QueryBuilderParemeter();

            param.FormId = MFGFormIdConst.SubSys_QM.PolicyQtySumModel;

            param.SelectItems = SelectorItemInfo.CreateItems(

                CONST_QM_PolicyQtySumModel.CONST_FBillHead.KEY_FQCBusinessType,

                CONST_QM_PolicyQtySumModel.CONST_FEntity.KEY_FUsePolicy);

            DynamicObjectCollection policyObjs = QueryServiceHelper.GetDynamicObjectCollection(this.View.Context, param);

            List<string> otherBTIds = policyObjs .Where(w => w.GetDynamicValue<string>(CONST_QM_PolicyQtySumModel.CONST_FBillHead.KEY_FQCBusinessType) == businessTypeId)

                    .Select(s => s.GetDynamicValue<string>(CONST_QM_PolicyQtySumModel.CONST_FEntity.KEY_FUsePolicy)).Distinct().ToList();

            useItems = items.Where(w => otherBTIds.Contains(w.GetDynamicValue<string>("Value"))).ToList();

            List<EnumItem> matchPolicys = new List<EnumItem>();

            foreach (DynamicObject item in useItems)

            {

                matchPolicys.Add(new EnumItem

                {

                    Value = item.GetDynamicValue<string>("Value"),

                    Caption = item.GetDynamicValue<LocaleValue>("Caption"),

                    Seq = item.GetDynamicValue<int>("Seq")

                });

            }

            //获取字段编辑器，设置新的下拉列表

            ComboFieldEditor cfe = this.View.GetFieldEditor<ComboFieldEditor>("FTestPolicy", row);//此处为二开增加的枚举下拉列表字段的标识

            cfe.SetComboItems(matchPolicys);

        }

       public override void AfterCreateNewEntryRow(BOS.Core.DynamicForm.PlugIn.Args.CreateNewEntryEventArgs e)

        {

            base.AfterCreateNewEntryRow(e);

            switch (e.Entity.Key)

            {

                case "FItemDetail"://此处为增加的二开下拉列表字段所在的单据体标识

                    string businessType = this.View.Model.GetValue<string>(CONST_QM_InspectBill.CONST_FBillHead.KEY_FBusinessType);

                    this.setOtherPolicyItemsByBusType(businessType,e.Row);

                    break;

            }

        }

    }
