Some elements from JSON object passed to MVC controller are NULL

I am trying to pass a JSON object to my MVC controller action via POST. The controller action is called but some elements of the object are NULL. The 'ArticleKey' is there but the 'MeasureDefinitions' are NULL (see below).
Here is the object which I am trying to parse (it gets appended with more values by the user):
var articleValues = [
{
'ArticleKey': {
'ArticleNo': 'ArticleNo',
'CustomerName': 'CustomerName',
},
'MeasureDefinitions ': [
{
'DisplayIndex': 0,
'MeasureType': 'MeasureType',
'Percentage': 99.99,
'OriginalPercentage': 0
}
]
}
];
My model looks like this:
public class ArticleValuesModel
{
[Key]
public ArticleKey ArticleKey { get; set; }
public List<MeasureDefinition> MeasureDefinitions { get; set; }
public string ArticleDescription { get; set; }
public bool AddToList { get; set; }
}
public class ArticleKey
{
public string ArticleNo { get; set; }
public string CustomerName { get; set; }
}
public class MeasureDefinition
{
public long DisplayIndex { get; set; }
[Key]
public string MeasureType { get; set; }
public double Percentage { get; set; }
public double OriginalPercentage { get; set; }
}
Here is my controller action:
[HttpPost]
public ActionResult UpdateArticleValuesJson(List<Gui.Models.ArticleValuesModel> modelList)
{
return RedirectToAction("Index");
}
Here is my Ajax POST:
$('#btnSaveArticleValues').click(function() {
$.ajax({
url: "/ArticleList/UpdateArticleValuesJson",
contentType: "application/json;charset=utf-8",
dataType: "JSON",
type: "POST",
data: JSON.stringify(articleValues),
success: function() {
console.log("Saved");
},
error: function(e) {
console.log(e);
}
});
});
Can you please help me to make the 'MeasureDefinitions' list accessible in my controller?

Removing the extra spaces in my JSON object like indicated by the_lotus did help to resolve the problem.

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)
{
...
}

How to send selected values to viewModel from multiselect (Kendo MultiSelect)

I'm using Kendo MultiSelect in my mvc5 project. So I have a View with multiselect:
#model Library.ViewModels.Models.BookViewModel
#{
ViewBag.Title = "Edit";
}
<script>
$(document).ready(function () {
$("#multiselect").kendoMultiSelect({
placeholder: "--Select Public Houses--",
dataTextField: "PublicHouseName",
dataValueField: "PublicHouseId",
autoBind: true,
dataSource: {
transport: {
read: {
dataType: "json",
url: "/book/getallpublichouses"
}
}
}
});
});
</script>
And I have 2 viewModels:
public class BookViewModel
{
public int BookId { get; set; }
public string Name { get; set; }
public string AuthorName { get; set; }
public int YearOfPublishing { get; set; }
public ICollection<PublicHouseViewModel> PublicHouses { get; set; }
}
public class PublicHouseViewModel
{
public int PublicHouseId { get; set; }
public string PublicHouseName { get; set; }
public string Country { get; set; }
public ICollection<BookViewModel> Books { get; set; }
}
In my Kendo MultiSelect a get all Public Houses from Book controller in JSON format. Next I selected some values:
So, how can I pass this selected values in public ICollection<PublicHouseViewModel> PublicHouses { get; set; } property in BookViewModel ?

You can use:
public int[] PublicHouses { get; set; }
instead of:
public ICollection<PublicHouseViewModel> PublicHouses { get; set; }
Or you can create a new field in BookViewModel only for posting.
When you are posting values from kendoMultiSelect, he posts only "dataValueField". After you post only id's you can do the rest of the logic in POST action.
It depends how you implemented your POST action and also on the relationship between two tables: Is it 1...N, or N....N.

Post Kendo Multiselect values to controller

I seem to be having a problem posting the selected values from my Kendo Multiselect widget to an action on my controller. I've never had this issue before and as far as I know I am doing everything right, but something is obviously causing an issue.
I have this input on my view:
<input id="ProductHandlingTypes" name="ProductHandlingTypes" style="width: 100%"/>
My ViewModel
public class BuyerProfileViewModel
{
public string UserId { get; set; }
public string Name { get; set; }
public int BuyerTypeId { get; set; }
public string Address { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zipcode { get; set; }
public string Description { get; set; }
public List<int> ProductHandlingTypes { get; set; }
public bool Producer { get; set; }
}
And my JavaScript:
$("#ProductHandlingTypes").kendoMultiSelect({
placeholder: "-- Select Type(s) --",
dataTextField: "Name",
dataValueField: "Id",
dataSource: new kendo.data.DataSource({
transport: {
read: {
url: "/Helper/GetProductHandlingTypes",
dataType: "json",
type: "GET"
}
}
})
});
$("#btnSave").on("click", function (e) {
e.preventDefault();
var formCreate = $(".form-register-buyer");
formCreate.validate();
if (formCreate.valid()) {
var options = {
url: $(formCreate).attr("action"),
type: $(formCreate).attr("method"),
data: $(formCreate).serialize()
};
$.ajax(options)
.done(function(data) {
if (data.success === true) {
window.location.href = data.redirectTo;
} else {
toastr.options = { "postiionClass": "toast-bottom-full-width" };
toastr.error(data.message, "Uh, Oh!");
}
});
}
});
When I submit my form to the controller I can see that all of the correct values are being passed except for ProductHandlingTypes. It just says it has a count of 1 and when I expand it out it says 0.

Breeze.js /NET+EF complex object behaviors rather strange

I’m developing a custom data access layer to be consumed in breeze.js
What I have:
The Model:
public class Product
{
[Key]
public int ProductId { get; set; }
public string Upc { get; set; }
public string Name { get; set; }
public decimal MsrpPrice { get; set; }
public int Quantity { get; set; }
public virtual ICollection<ProductFeature> Features { get; set; }
public virtual B2BCategory InB2BCategory { get; set; }
public virtual ICollection<ImageDescriptor> Images { get; set; }
public int CategoryId {get; set;}
}
public class ProductFeature
{
public int ProductId { get; set; }
public string Name { get; set; }
public string GroupName { get; set; }
public string Operation { get; set; }
public decimal Value { get; set; }
}
public class ImageDescriptor
{
public int ProductId { get; set; }
public string Uri { get; set; }
public DateTime Updated { get; set; }
public bool IsDefault { get; set; }
}
The Context Provider:
public class ProductContextProvider : ContextProvider
{
private readonly ProductRepository repo =new ProductRepository();
public IQueryable<B2BCategory> Categories
{
get { return repo.Categories.AsQueryable(); }
}
public IQueryable<Product> Products
{
get
{
return repo.Products.OrderBy(p => p.ProductId).AsQueryable();
}
}
protected override string BuildJsonMetadata()
{
var contextProvider = new EFContextProvider<ProductMetadataContext>();
return contextProvider.Metadata();
}
protected override void SaveChangesCore(SaveWorkState saveWorkState)
{…
}
// No DbConnections needed
public override IDbConnection GetDbConnection()
{
return null;
}
protected override void OpenDbConnection()
{
// do nothing
}
protected override void CloseDbConnection()
{
// do nothing
}
}
internal class ProductMetadataContext : DbContext
{
static ProductMetadataContext()
{
Database.SetInitializer<ProductMetadataContext>(null);
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Configurations.Add(new ProductFeatureConfiguration());
modelBuilder.Configurations.Add(new ImageDescriptorConfiguration());
}
public DbSet<Product> Products { get; set; }
public DbSet<B2BCategory> Categories { get; set; }
}
internal class ImageDescriptorConfiguration : EntityTypeConfiguration<ImageDescriptor>
{
public ImageDescriptorConfiguration()
{
// I tried to mess up with key orders
HasKey(i => new { i.Uri, i.ProductId});
}
}
internal class ProductFeatureConfiguration : EntityTypeConfiguration<ProductFeature>
{
public ProductFeatureConfiguration()
{
HasKey(f => new { f.ProductId, f.Name });
}
}
I’m stuffing the Features and Images properties of a Product directly:
product.Features = new Collection<ProductFeature>();
product.Images = new Collection<ImageDescriptor>();
…
var imgd = new ImageDescriptor
{
ProductId = product.ProductId,
Updated = DateTime.Now,
Uri = defsmall,
IsDefault = !product.Images.Any()
}
product.Images.Add(imgd);
…
var pf = new ProductFeature
{
ProductId = product.ProductId,
GroupName = "Size",
Name = size,
Value = size == "Small" ? new decimal(.75):size == "Medium" ? new decimal(1.3):new decimal(1.8),
Operation = "*"
};
product.Features.Add(pf);
Totally there are, say, 3 product features and 2 images per product item.
In the client side I query this like:
return entityQuery.from('Products').using(EntityManager).execute();
And… I’ve got the very strange thing:
The images property contains an empty array, the features property contains an array of 5!!! elements – 3 of type ProductFeature and 2 of type ImageDescriptor.
I think this is a bug – could you help me, please?

I don't see any code that creates a breeze EntityManager and adds or attaches your newly created entities and then saves them. Please take a look at the Breeze examples in the downloadable zip from the BreezeJs website.
