**【应用场景】**
在单据列表界面打印指定行逻辑。本案例模拟列表的[连续套打预览所选分录]
**【案例演示】**
<1>编写列表插件，代码如下。
``` csharp
using Kingdee.BOS.Core.CommonFilter;
using Kingdee.BOS.Core.Const;
using Kingdee.BOS.Core.DynamicForm.PlugIn.Args;
using Kingdee.BOS.Core.List;
using Kingdee.BOS.Core.List.PlugIn;
using Kingdee.BOS.Core.NotePrint;
using Kingdee.BOS.JSON;
using Kingdee.BOS.Util;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
namespace Kingdee.BOS.PlugInTest
{
/// <summary>
/// 【列表插件】二开连续套打所选分录
/// </summary>

public override void AfterBarItemClick(AfterBarItemClickEventArgs e)
{

{

return;
// 获取列表过滤选择的实体标识
string headEntityKey = string.Empty;

}
// 模板获取可以通过GetTemplatesByFormId方法获取
// 字典格式,key-套打模板ID,value-套打模板对应语言环境下的名称
// var templateDic = PrintServiceHelper.GetTemplatesByFormId(this.Context, this.View.BillBusinessInfo.GetForm().Id);
// 构建打印任务

{
var model = printJobsItemList.FirstOrDefault(x => x.BillId.Equals(selectedRow.PrimaryKeyValue));
if (model == null)
{
model = new PrintJobItem(selectedRow.PrimaryKeyValue, TemplateId);
// 老版本选中分录集合
model.SelectedEtyIds = new List<string>();
// 新版本树形选中分录集合
model.RootNode = new PrintSelectNode();
// 单据头
model.RootNode.EntityKey = headEntityKey;

// 单据体
model.RootNode.SelectNode = new List<PrintSelectNode>();
