ASP.NET Core Partialview does not bind to the class with formserialize

I want to create a Quiz, add questions to the quiz, and add answers to the question. I bound all items with asp-for, serialize my form, and send it to the controller, but they don't bind.
My classes:
public class Answer
{
[Key]
public Guid Id { get; } = Guid.NewGuid();
public string Content { get; set; }
public Guid QuestionId { get; set; }
}
public class Question
{
[Key]
public Guid Id { get; } = Guid.NewGuid();
public string Content { get; set; }
public Guid QuizId { get; set; }
public ICollection<Answer> Answers { get; set; } = new List<Answer>() {
new Answer() { Content = "Answeeeer" },
new Answer() { Content = "Answeeeer2" },
new Answer() { Content = "Answeeeer3" }
};
}
public class Quiz
{
[Key]
public Guid Id { get; } = Guid.NewGuid();
public string Name { get; set; }
public ICollection<Question> Questions { get; set; } = new List<Question>() { };
}
Quiz view:

This is my controller:

public QuizesController(ApplicationDBContext context)
{
_context = context;
}
public async Task<IActionResult> Index()
{

return View(newquiz);

[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create(Quiz quiz)
{
if (ModelState.IsValid)
{
_context.Add(quiz);
await _context.SaveChangesAsync();
return RedirectToAction(nameof(Index));
}
return View(quiz);
}
public IActionResult AddBlankQuestion(Quiz model)
{
Question question = new Question();
//question.Answers.Add(new Answer() { QuestionId = question.Id, Content = "Salaaam Necesem" });
return PartialView("EditorTemplates/Question", question);
}
public IActionResult AddBlankAnswer(Question model)
{
var newanswer = new Answer() { QuestionId = model.Id, Content = String.Empty };
return PartialView("EditorTemplates/Answer", newanswer);
}
}
I want to create a Quiz, add questions to the quiz, and add answers to the question. I bound all items with asp-for, serialize my form, and send it to the controller, but they don't bind.

public ICollection Questions { get; set; }
You don't bind Content to your list ICollection<Question> Questions , so the Questions list is null.
You need to set name like name="Questions[0].Content" and name="Questions[1].Content".

Asp.net Core PartialView submits form unnecessarily

I want to create a Quiz website with Asp. I want to create Quiz, add questions to the quiz, and add answers to the question. Add question button adds a question, but the Addanswer button submits the form instead of adding an answer to the question.
My classes:
public class Answer
{
[Key]
public Guid Id { get; } = Guid.NewGuid();
public string Content { get; set; }
public Guid QuestionId { get; set; }
public class Question
{
[Key]
public Guid Id { get; } = Guid.NewGuid();
public string Content { get; set; }
public Guid QuizId { get; set; }
public ICollection<Answer> Answers { get; set; } = new List<Answer>() {
new Answer() { Content = "Answeeeer" },
new Answer() { Content = "Answeeeer2" },
new Answer() { Content = "Answeeeer3" }
};
public class Quiz
{
[Key]
public Guid Id { get; } = Guid.NewGuid();
public string Name { get; set; }
public ICollection<Question> Questions { get; set; } = new List<Question>() { };
In front side I have Question and Answer Partial views:
Question Partial View:
#model QuizIt_Tests.Entities.Question
<hr style="height: 4px; color: black;" />
<div class="w-100 p-3 px-5 my-3">

<div id="answerRows #Model.Id" class="w-75">
#Html.EditorFor(model => model.Answers)
<button class="btn btn-primary" id="addAnswer #Model.Id">Add Answer</button>
</div>
</div>
#section Scripts {

$.ajax({

success: function (html) {
$("#answerRows " + #Model.Id").append(html); },

});
return false;
});
</script>
}
Answer Partial View:
#model QuizIt_Tests.Entities.Answer
<div class="row" style="background-color:red; margin: 20px;">
<label asp-for="Content" class="control-label">Answer Content</label>
<input asp-for="Content" class="form-control" value="#Model.Content" />
<span asp-validation-for="Content" class="text-danger"></span>
</div>
My Controller:
public class QuizesController : Controller
{
private readonly ApplicationDBContext _context;
public QuizesController(ApplicationDBContext context)
{
_context = context;
}
public IActionResult AddBlankQuestion(Quiz model)
{
Question question = new Question();
return PartialView("EditorTemplates/Question", question);
}
public IActionResult AddBlankAnswer(Question model)
{
return PartialView("EditorTemplates/Answer", new Answer() { QuestionId = model.Id });
}
}

You did not specify the type attribute in the button, which by default is equal to submit which causes the form to be submitted, to change its behavior, change the type value to button as follows.
<button type="button" class="btn btn-primary" id="addAnswer #Model.Id">Add Answer</button>

How to pass data between views and controller?

This is our Home Index:
#model ELearning.Data.ELearningEgitimDTO
#{
ViewBag.Title = "Home Page";
}
<div class="jumbotron">
#if (TempData["message"] != null)
{
<div class="alert alert-info" role="alert">#TempData["message"]</div>
}
<div>
<div>
#if (Model.EgitimTuru == 5)

}
else {
document.getElementById("message").innerHTML = "Video tamamlanmadan eğitimi bitiremezsiniz.."
}

This is our main model:
public class ELearningEgitimDTO
{
public ELearningEgitimDTO() { }
public ELearningEgitimDTO(string PerNr, int ID)
{
this.ID = ID;
this.PerNr = PerNr;

public string PersonelAdi { get; set; } // eğitimi veren
public int FileId { get; set; }
public string FileName { get; set; }
public string[] Adi { get; set; }
}
This is our model:
public class VideoLogsModel
{
public int EgitimFilesId { get; set; }
public int PerNr { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
}
This is our Home Controller:
public class HomeController : Controller
{
public ActionResult Index(int EgitimId=4, string PerNr="2")
{
ELearningService service = new ELearningService();
ELearningEgitimDTO egitim = new ELearningEgitimDTO(PerNr, EgitimId);
return View(service.getInfo(egitim)); //eğitim bilgileri istenirken egitimId ve egitim kullanıcıdaki eğitmenin perNr si verilmeli!!

ELearningService service = new ELearningService();
service.UpdateLogs(user);
TempData.Add("message", String.Format("Eğitiminiz Tamamlanmıştır!"));
return RedirectToAction("Index", "Home");
}
}
My question is how can i pass the model from home index to video controller and then to video index?
Video Index doesn't run. It goes to video index but then it runs home index again.
Also it runs egitimibitir() function before button's onclick function.

You send an ajax request to your service. (endpoint => GetEndDate) I think you can change your code like that,
$.ajax({
type: "POST",
url: "/Video/GetEndDate", //your reqeust url
contentType: "application/json; charset=utf-8",
data: JSON.stringify({
// your data here
}),
success: function (data) {
// check state of data
// after check window.location = // redirect url
},
error: function (data) {
// handle exception
}
});
You can change your controller method to a data controller. (not an ActionResult. create a custom result object which include your data and your success state. you can use this custom result object every ajax requests for return state and data). If an exception occurs while executing "GetEndDate" method, you need to handle exception and you need to show it to client. You send exception or your success complete response to to client(view). (you can handle your exception data in ajax error: function)

How to Ajax call to controller with value pass?

$(document).ready(function(e) {

Your javascript code should be wrapped in a jQuery load function, like this:
$(function () {
//Paste all your java script here
});
That was the only change I made on my side and the AJAX call to GetFile in the Document controller is now working

As Denis Wessels said you have to enclose jquery code inside document ready block
$( document ).ready(function() {
var currentDataItem = this.dataItem(this.select());
id = currentDataItem.Id;
var p = { Data: $('#fileId').val() };
$('#fileId').click(function () {
$.ajax(
{
url: '#Url.Action("GetFile", "Document")?id=' + id,
//url: '/Document/GetFile',
type: "POST",
// data: {Id:id},
success:function(data)
{
},
error:function(e)
{
}
});
})
});

First all let me correct certain mistakes in your code. In view haven't passed any id that could be passed in the action method. So either in the FileManager class change the returntype of GetData method as
Dictionary<int,string>
OR
create a model class say FileManagerModel as follows
public class FileManagerModel
{
public int ID {get;set;}
public string FileName{get;set;}
}
and change the return type as
List<FileManagerModel>
accordingly change the model in the view as
#model Dictionary<int, string> // If the return type is Dictionary<int,string>
and then in the view change your for loop as follows
#foreach(var file in Model)
{
<tr>
<td>
<li>
#file.Value
</li>
</td>
</tr>
<br />
}
and also change your GetFile method as follows
public FileStreamResult GetFile(int? id)
{
string fileName = "IFrameTest.txt";
var t = ConfigurationManager.AppSettings["FilePath"];
string filePath = ConfigurationManager.AppSettings["FilePath"] + fileName;
FileStream fs = new FileStream(Server.MapPath(filePath), FileMode.Open, FileAccess.Read);
return File(fs, "text/plain");
}
add nullable int arguement in your method as on page load your id will be null.
As the method by default is HTTPGET method in your Ajax call you need to make changes as follows
<script>
$(document).ready(function(e) {
var id = $('#fileId').text();
$('#fileId').click(function (event) {
event.preventDefault();
var id = $(this).data("id");
$.ajax(
{
url: '#Url.Action("GetFile", "Document")',
type: "GET",
data: { id: id },
success:function(data)
{
},
error:function(e)
{
}
});
})
});
</script>
On doing these changes it worked for me .I hope this will rectify your issue
UPDATE
If you are using IEnumerable pass the Id in the data attribute as
#file.Name

Issue passing back dynamic string array

I have a form inside a modal popup, The user can enter text in a text box and click a plus button which dynamically adds the text they have typed in to a div so they can then proceed to add another one.
<div class="form-group">
<label class="control-label col-sm-4" for="prefix">
Cast <span style="color:red">*</span>
</label>
<div class="col-sm-5">
<input type="text" class="form-control col-sm-5" id="Cast" />
</div>
<div class="col-sm-1">
<button type="button" id="btnNewCast" class="btn btn-default">+</button>
</div>
</div>
<div class="form-group">
<label class="control-label col-sm-4" for="prefix"></label>
<div class="col-sm-6" id="newCast">
</div>
</div>
As shown here:
The NewCast is where I display the entered value by jquery.
When they click btnNewCast the following script is called
$("#btnNewCast").click(function () {
$("#newCast").append("<span class='label label-success label-as-badge custom-line-height' id='cast[]'><i class='glyphicon glyphicon-tag'></i> "+ $("#Cast").val() + "</span><br/>");
$("#Cast").val('');
});
Which looks like this:
The HTML is as follows:
<span id="cast[]" class="label label-success label-as-badge custom-line-height">
<i class="glyphicon glyphicon-tag"></i>
They Appear Here
</span>
When they press submit on on the form I pass the values back as shown here:
$("#btnAddMovie").click(function() {
$.ajax({
url: '/Movies/Add',
//data: $('NewMovie').serialize(),
data: { "Title": $("#Title").val(), "Classification": $("#Classification").val(), "Rating": $("#Rating").val(), "ReleaseDate": $("#ReleaseDate").val(), "Cast": $("#Cast").val() },
cache: false,
type: "POST",
success: function (result) {
if (result.success) {
}
},
error: function (result) {
alert("Error");
}
});
});
Which get mapped to my Model, and is working correctly.
Controller:
[HttpPost]
public ActionResult Add(Movie model)
{
return View();
}
My Model is declared like this:
public int MovieId { get; set; }
public int Rating { get; set; }
public int ReleaseDate { get; set; }
public string Title { get; set; }
public string Classification { get; set; }
public string Genre { get; set; }
public string[] Cast { get; set; }
The issue I have is as you can see Cast is a string array, the items the user enters (which is shown in the pictures) I'm trying to map them all to the Cast string array when they post.
I have tried
"Cast": $("#cast[]").val()
But I get a jquery error when posting, unrecognized expression
I can't get it to map correctly..
** Update** Complete post method
$("#btnAddMovie").click(function () {
var stringArr = $('span[data-id="cast[]"]').map(function() {
return $(this).text().trim();
});
$.ajax({
url: '/Movies/Add',
//data: $('NewMovie').serialize(),
data: { "Title": $("#Title").val(), "Classification": $("#Classification").val(), "Rating": $("#Rating").val(), "ReleaseDate": $("#ReleaseDate").val(), "Cast": stringArr },
cache: false,
type: "POST",
success: function (result) {
if (result.success) {
}
},
error: function (result) {
alert("Error");
}
});
});

Few issues :
<span> does not have .val() (value), use text().
The error
Unrecognized expression
Is because : [] - special chars are not allowed in plain #.. selectors. Use [id=""]
So use map() to iterate over this.
var stringArr = $('span[id="cast[]"').map(function(){
return $(this).text().trim();
});
Also, the way you are creating span through jQuery, the ID = cast[] is getting duplicated, and Duplicated Ids is Invalid markup. Use class attribute or data-* attributes like data-id="cast[]. The code would then be :
var stringArr = $('span[data-id="cast[]"').map(function(){
return $(this).text().trim();
});
