ActiveReport+MVC+ajax 通过前台参数传递如何动态绑定数据源？

收藏

1.请问下 AcitveReport.Parameters 这个能动态赋值吗？有实际例子吗？
2.以下是我绑定数据源的代码，现在我着需要根据页面传递的参数来绑定数据源
例如： DataTable tb = DBContext.ExecuteDataTable("SELECT Name,Sex,Age FROM Student");
前台传递一个id的参数，DataTable tb = DBContext.ExecuteDataTable("SELECT Name,Sex,Age FROM Student where id="+id);
根据不同的id获取不同的数据源，使用ajax 后直接跳过pageDocument.LocateDataSource ，无法绑定，请问怎么通过参数来绑定不同数据源

public ActionResult Index()

   {
      GetReport();
      return View();
   }

   public void GetReport()
   {
      GrapeCity.ActiveReports.PageReport report = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(Server.MapPath("/PageReport1.rdlx")));
      PageDocument pageDocument = new PageDocument(report);
      System.Action<object, LocateDataSourceEventArgs> action = new Action<object, LocateDataSourceEventArgs>(Document_LocateDataSource);
      pageDocument.LocateDataSource += (sender, args) =>
      {
      action(sender, args);
      };
      ViewData.Model = report;
   }

   private void Document_LocateDataSource(object sender, LocateDataSourceEventArgs args)
   {
      List<Student> list = new List<Student>();
      //
      DataTable tb = DBContext.ExecuteDataTable("SELECT Name,Sex,Age FROM Student");
      foreach (System.Data.DataRow row in tb.Rows)
      {
      Student stu = new Student();
      stu.Name = row["Name"].ToString();
      stu.Sex = row["Sex"].ToString();
      stu.Age = row["Age"].ToString();
      list.Add(stu);
      }
      int ss = args.Report.Parameters.Count();
      args.Data = list;
   }
