添加某些列时，Crystal Report会变空

Question

我有这个CrystalReport，此报告显示来自4个数据表的数据 表格是，产品，订单，发票和客户 我的问题是报告显示我添加的所有数据，但不显示客户列。

当我尝试将任何列从客户添加到报告中时，报告会显示为空，并且不显示任何内容。

我创建了一个数据集作为数据源，并确保数据集由数据填充。

这是填充数据集的代码

public ActionResult Report(int CustmId, int OrderId)
    {

        DataSet1 ds = new DataSet1();
        ds.EnforceConstraints = false;

        SqlConnection con = new SqlConnection("Data Source=ENTERPRISE-PC;Initial Catalog=Fakturor;Integrated Security=True");
        con.Open();
        String query = "select * From Customer where id= "+CustmId+"";
        SqlDataAdapter adapter = new SqlDataAdapter(query, con);
        adapter.Fill(ds,"Customer");

        adapter = new SqlDataAdapter("SELECT * from Products v JOIN OrderVaror ov on v.id = ov.IdVara where ov.IdOrder = "+OrderId+"", con);
        adapter.Fill(ds,"Products ");

        adapter =  new SqlDataAdapter("SELECT * from [Order] where id ="+OrderId+"",con);
        adapter.Fill(ds, "Order");


        adapter = new SqlDataAdapter("Select id, Datum, Price, PaymentDay, moms from Invoice", con);
         adapter.Fill(ds, "Invoice");

        con.Close();



            ReportDocument rd = new ReportDocument();
            rd.Load(Path.Combine(Server.MapPath("~/Repport/CrystalReport1.rpt")));
            rd.SetDataSource(ds);

            Response.Buffer = false;
            Response.ClearContent();
            Response.ClearHeaders();


            try
            {
                Stream stream = rd.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
                stream.Seek(0, SeekOrigin.Begin);
               // return View("ViewPage1");
               return File(stream, "application/pdf", "EverestList.pdf");
            }
            catch (Exception ex)
            {
                throw;
            }
    }
