单据表体弹出物料附件列表二开示例

单据表体弹出物料附件列表，以采购申请单为例。在BOS设计器中打开采购申请单，明细信息增加菜单“查看物料附件”。

在采购申请单的表单插件中挂上插件，插件代码示例如下：

using Kingdee.BOS.Core;
using Kingdee.BOS.Core.Attachment;
using Kingdee.BOS.Core.Bill.PlugIn;
using Kingdee.BOS.Core.DynamicForm;
using Kingdee.BOS.Core.List;
using Kingdee.BOS.Orm.DataEntity;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Kingdee.BOS.Printing.PlugIn.Test
{
    public class ShowAttachmentPlugIn : AbstractBillPlugIn
    {
        public override void EntryBarItemClick(Core.DynamicForm.PlugIn.Args.BarItemClickEventArgs e)
        {
            base.EntryBarItemClick(e);
            if (e.BarItemKey == "PAEZ_tbButton")
            {
                int rowIndex = this.View.Model.GetEntryCurrentRowIndex("FEntity");
                object entryPkValue = this.View.Model.GetEntryPKValue("FEntity", rowIndex);
                object obj = this.View.Model.GetValue("FMaterialId", rowIndex);
                if (obj is DynamicObject)
                {
                    ShowAttachmentList(Convert.ToString((obj as DynamicObject) ["Id"]));
                }
            }
        }
        private void ShowAttachmentList(string interId)
        {
            AttachmentKey attachmentKey = new AttachmentKey()
            {
                BillType = "BD_MATERIAL",
                BillNo = "",
                BillInterID = interId,
                EntryKey = " ",
                EntryInterID = "-1",
                OperationStatus = Core.Metadata.OperationStatus.E
