在gridview中显示名称而不是引用ID

Question

我有4个表tblEmployee，tblDepartment.tblCompany，tblNationality，第一个表是父表，所有三个表都带有引用ID＆＃39; s。 follwoing是我的代码，用于获取员工数据详细信息

public class MainActivity extends Activity implements OnItemSelectedListener {
    Spinner spinnerOsversions;
    TextView selVersion;
    private String[] state = { "Cupcake", "Donut", "Eclair", "Froyo",
       "Gingerbread", "HoneyComb", "IceCream Sandwich", "Jellybean",
       "kitkat" };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        System.out.println(state.length);
        selVersion = (TextView) findViewById(R.id.selVersion);
        spinnerOsversions = (Spinner) findViewById(R.id.osversions);
        ArrayAdapter<String> adapter_state = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, state);
        adapter_state.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinnerOsversions.setAdapter(adapter_state);
        spinnerOsversions.setOnItemSelectedListener(this);
    }

    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        spinnerOsversions.setSelection(position);
        String selState = (String) spinnerOsversions.getSelectedItem();
        selVersion.setText("Selected Android OS:" + selState);
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
      // TODO Auto-generated method stub
    }
}

我正在使用DataViewController.js这是一个脚本文件（AngularJS）

public JsonResult EmployeeRequests()
{
    List<EmployeeRequests> CO = new List<EmployeeRequests>();
    using (EmployeeContext dc = new EmployeeContext())
    {
        //var cust = dc.Customers.OrderBy(a => a.ContactName).ToList();
        dc.Configuration.LazyLoadingEnabled = false;

       var cust = dc.Employees.OrderBy(a => a.EmpName).ToList();
          foreach (var i in cust)
        {
            var requests = dc.Requests.Where(a => a.EmployeeID.Equals(i.EmployeeID)).OrderBy(a => a.RequestDate).ToList();
            CO.Add(new EmployeeRequests
            {
                Employee = i,
                Requests = requests
            });
        }        

    }
    return new JsonResult { Data = CO, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}

DataView.cshtml如下图所示，我试图显示O.Company.CompName，O.Department.DeptName，O.Natioality.NatName，但它什么也没显示。

 angular.module('MyApp')  //extending angular module from first part
.controller('DataViewController', function ($scope, RequestService) { //explained about controller in Part2
    $scope.Requests = [];


    RequestService.GetRequests().then(function (d) {
        $scope.Requests = d.data
    });
})

.factory('RequestService', function ($http) { //explained about factory in Part2
    var fac = {};
    fac.GetRequests = function () {
        return $http.get('/Data/EmployeeRequests');
    }
    return fac;
});
