Passing a list from angular to c# through http request

My method in c# receives a list as a parameter, I am trying to call this method in angular by passing it an array, but the problem is that the info doesn't reach the c# method, the list is always empty, even though there was information in the angular array.
export class StationAllocationPostModel{
idAppDeviceOwnerEntity: number;
idAppDeviceOwnerEntityOriginal: number;
idAppDeviceOwnerEntityRentalLocationId: number;
Observations: string;
selectedAppDevices: StationAllocationModel[];
}
createNewStationAllocation(selectedAppDevices: StationAllocationPostModel){
return this.post("home/CreateAppDeviceRentalLocationAllocation", selectedAppDevices, {
params: {
'idAppDeviceOwnerEntity': selectedAppDevices.idAppDeviceOwnerEntity,
'idAppDeviceOwnerEntityRentalLocationId': selectedAppDevices.idAppDeviceOwnerEntityRentalLocationId,
'Observations': selectedAppDevices.Observations,
'selectedAppDevices': selectedAppDevices.selectedAppDevices
}
});
}
public post(url: string, data: any, options = null) {
return new Promise<any>((resolve, reject) => {
let response;
this.http.post(
this.baseUrl + url,
{
data: data
},
{
headers: options ? options.headers : null,
observe: options ? options.observe : null,
params: options ? options.params : null,
reportProgress: options ? options.reportProgress : null,
responseType: options ? options.responseType : null,
withCredentials: options ? options.withCredentials : null
}
)
.subscribe(
data => {
response = data;
if (response && !response.success) {
if (response.response.ServerResponse[0].MessageType == "NOSESSIONEXCEPTION") {
localStorage.removeItem('userSession');
this.router.navigate(['/login'], { queryParams: { returnUrl: this.router.url } });
}
}
},
error => {
resolve(null);
this.handleError(url, options ? options.params : null );
console.log(error);
}, () => {
if (response) {
resolve(response);
} else {
resolve(null);
}
}
);
})
}
This is my c# method:
public Object CreateAppDeviceRentalLocationAllocation(<other params>, List<AppDeviceRentalLocationAllocationHistoryExtended> selectedAppDevices)
{
...
}
I am expecting that the c# method receives a list with elements, but it always comes out empty for some reason. The 'other params' are getting the right information, so I don't know what's wrong with the list.
Sorry for the long post, I'm new here.

Could you please form a param object on the C# method that holds the following :
public class SelectedAppDevice
{
public int idAppDevice { get; set; }
public int idAppDeviceOwnerEntity { get; set; }
public int idAppDeviceOwnerEntityRentalLocationId { get; set; }
public string Observations { get; set; }
public string DeviceId { get; set; }
public string EntityRentalLocationName { get; set; }
public DateTime CreationDate { get; set; }
public DateTime EndDate { get; set; }
public string CreatedByUserName { get; set; }
public int RentalStatus { get; set; }
public int idAppDeviceRental { get; set; }
public bool IsRentalStart { get; set; }
public bool IsRentalEnd { get; set; }
public object idNextExpectedEntityRentalLocationName { get; set; }
public object NextExpectedEntityRentalLocationName { get; set; }
public string LastKnownEntityRentingId { get; set; }
public string CallerId { get; set; }
public int RentalStatusId { get; set; }
public int DeviceStatusId { get; set; }
}
public class Data
{
public string Observations { get; set; }
public int idAppDeviceOwnerEntityRentalLocationId { get; set; }
public int idAppDeviceOwnerEntity { get; set; }
public List<SelectedAppDevice> selectedAppDevices { get; set; }
}
public class RootObject
{
public Data data { get; set; }
}
and make it as a controller method parameter :
public Object CreateAppDeviceRentalLocationAllocation(RootObject param)
{
...
}

Have to show Model data into View using JavaScript MVC C#

I have page where I save user, contact and address details. The users could have multiple contact and address, So I have added the control to populate dynamically.
Form is working fine, except if any exception occurrs, the controller action return view with model.
This follows the structure of Model:
Model
public class UserModel
{
public UserDetail User { get; set; }
public IList<UserContact> Contact { get; set; }
public IList<UserAddress> Address { get; set; }
}
Contact Model :
public partial class UserContact
{
public int Id { get; set; }
public int UserId { get; set; }
public string ContactType { get; set; }
public string Mobile { get; set; }
public string Email { get; set; }
public bool IsActive { get; set; }
public virtual UserDetail UserDetail { get; set; }
}
Address Model
public partial class UserAddress
{
public int Id { get; set; }
public int UserId { get; set; }
public string AddressType { get; set; }
public string AddressName { get; set; }
public string AddressLine1 { get; set; }
public string AddressLine2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string PostCode { get; set; }
public bool IsActive { get; set; }
public virtual UserDetail UserDetail { get; set; }
}
When value return, the following function suppose to check the Contact and Address and then then populate each record in dynamic created input section in view.
<script type="text/javascript">
$(document).ready(function () {
AddDynamicData();
function AddDynamicData() {
var valuesContacts = eval('#Html.Raw(Json.Encode(Model.Contact))');
var valuesAddresses = eval('#Html.Raw(Json.Encode(Model.Address))');
if (valuesContacts != null) {
var iContact = 0;
$(valuesContacts).each(function () {
$("#divContact").append(GetDynamicContact(iContact++, valuesContacts.contactType, valuesContacts.mobile, valuesContacts.email));
});
}
if (valuesAddresses != null) {
var iAddress = 0;
$(valuesAddresses).each(function () {
$("#divAddress").append(GetDynamicAddress(iAddress++, valuesAddresses.addressType, valuesAddresses.addressName, valuesAddresses.addressLine1, valuesAddresses.addressLine2, valuesAddresses.city, valuesAddresses.state, valuesAddresses.postCode));
});
}
}
</script>
The Function does not work properly, It does create the field but does not populate the user input data into textbox... Please advise how to fix the same and how to populate the records in view....
Added the View after submitting the form
<Update>
#Updated New Code with function & added screenshot

When creating double dropdown SelectList with JQuery on POST returns 0. ASP.Net CORE 2.1

I have created two dropdownlists, of which one acts as a filter for the other. So, with dropdown Customer a customer is selected and only a limited set of ClientUsers is presented in in the dropdown ClientUser. I use a Jquery function to make this happen.
The selection works excellent, but when I POST the form the ClientUser is set to 0, instead of the choice.
The View is as follows (simplified for readability purposes):
#model DropDownTester2.Models.CaseViewModel
<form asp-action="Maak">
<label asp-for="CaseTitle" class="control-label"></label>
<input asp-for="CaseTitle" class="form-control" />
<select id="customerId" asp-for="CustomerId" asp-items='#(new SelectList(ViewBag.customers, "CustomerId", "CompanyName"))'>
<option>Select Customer Name</option>
</select>
<select id="clientUserId" asp-for="ClientUserId" asp-items='#(new SelectList(string.Empty, "ClientUserId", "LastName"))'>
</select>
<input type="submit" value="Maak" class="btn btn-default" />
</form>
#section Scripts {
#{await Html.RenderPartialAsync("_ValidationScriptsPartial");}
<script src="~/lib/jquery/dist/jquery.js"></script>
<script type="text/javascript">
$(function () {
$("#customerId").change(function () {
var url = '#Url.Content("~/")' + "Case/getClientUserById";
var ddlsource = "#customerId";
$.getJSON(url, { id: $(ddlsource).val() }, function (data) {
//$.getJSON("#Url.Action("getClientUserById","Case")", { id: $(ddlsource).val() }, function (data) {
var items = '';
$("#clientUserId").empty();
$.each(data, function (i, row) {
items += "<option value='" + row.value + "'>" + row.text + "</option>";
});
$("#clientUserId").html(items);
})
});
});
</script>
}
The CaseViewModel is:
public class CaseViewModel
{
public int CaseId { get; set; }
public string CaseTitle { get; set; }
public int CustomerId { get; set; }
public int ClientUserId { get; set; }
public IEnumerable<Customer> CustomerList { get; set; }
public IEnumerable<ClientUser> ClientUserList {get; set;}
My Model for Case is:
public class Case
{
public int CaseId { get; set; }
public string CaseTitle { get; set; }
public string CaseRoleDescription { get; set; }
public int CustomerId { get; set; }
public int ClientUserId { get; set; }
public virtual Customer Customer { get; set; }
public virtual ICollection<ClientUser> ClientUsers { get; set; }
}
Finally my controllers are :
// GET: Case/Maak
public IActionResult Maak()
{
ViewBag.customers = _context.Customer.ToList();
return View();
}
public JsonResult getClientUserById(int id)
{
List<ClientUser> list = new List<ClientUser>();
list = _context.ClientUser.Where(c => c.Customer.CustomerId == id).ToList();
list.Insert(0, new ClientUser { ClientUserId = 0, LastName = "Please select a clientuser" });
return Json(new SelectList(list, "ClientUserId", "LastName"));
}
// POST: Case/Maak
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Maak(CaseViewModel model)
{
if (ModelState.IsValid)
{
var newCase = new Case
{
CaseId = model.CaseId,
CaseTitle = model.CaseTitle,
CustomerId = model.CustomerId,
ClientUserId = model.ClientUserId
};
_context.Add(newCase);
await _context.SaveChangesAsync();
return RedirectToAction(nameof(Index));
}
ViewData["CustomerId"] = new SelectList(_context.Set<Customer>(), "CustomerId", "CustomerId", model.CustomerId);
return View(model);
}

I can't reproduce your issue :
The difference part of codes is that i create the Customer/ClientUser manually but that shouldn't be the issue cause :
public class Customer {
public int CustomerId { get; set; }
public string CompanyName { get; set; }
}
public class ClientUser
{
public int ClientUserId { get; set; }
public string LastName { get; set; }
}
You may search the "ClientUserId " in your pages to confirm whether other function reset the value .
As a workaround, you can also :
Create a hidden filed in your page and bind to your model property , create the select change event javascript function to set the value based on the selection .
Use Jquery to get the selected opinion , use Ajax to call action function and pass the value as parameter .

Json invoke not working after moving to mvc5

Same code stopped working after move to mvc5. In the following code I am trying to get cities for a country which is chosen in a dropdownlist using json.
The View.cshtml
#Html.DropDownList("CountryId", (SelectList)ViewBag.Countries, " -- choose a country -- ", new { onchange = "CountryDDLChanged()", #class = "form-control" })
JavaScript file (a part of the code)
function CountryDDLChanged() {
var url1 = "../Country/GetCitiesByCountryId";
var countryid = $("#CountryId").val();
$.ajax({
type: "GET",
url: url1,
data: { countryId: countryid },
dataType: "json",
success: function (result) {
alert("yes");
},
error: function(req, status, error){
alert(error);
}
});
}
CountryController
public JsonResult GetCitiesByCountryId(int countryId)
{
JsonResult result = new JsonResult();
using (var db = new DBContext())
{
List<City> cities = db.Cities.Where(c => c.CountryId == countryId).ToList();
result.Data = cities;
result.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
}
return result;
}
When I digg down in the code and debugging it. it generates this error.
he ObjectContext instance has been disposed and can no longer be used for operations that require a connection.
Why this works in MVC4 but not in MVC5? is it because of different version of EF?
how can I solve it?
UPDATED: Here is my Country Entithy and City :
[Table("Country")]
public class Country
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int CountryId { get; set; }
[StringLength(100)]
public string Name { get; set; }
public virtual List<City> Cities { get; set; }
public virtual List<Member> Members { get; set; }
public virtual List<MemberFee> MemberFees { get; set; }
}
[Table("City")]
public class City
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int CityId { get; set; }
public string Name { get; set; }
public int CountryId { get; set; }
[ForeignKey("CountryId")]
public virtual Country Country { get; set; }
public virtual List<Member> Members { get; set; }
}
