Getting viewmodel value null on Http Post method,

My View page, it contains many dynamic controls
I know this question has been asked and answered a dozen of times but none of the solutions help me.
I have a following ViewModel which is consisted of QuestionBatch data model,listResponseTag and a list of listQuestion data model.
View Model
public class VM_Questionaire
{
public QuestionBatch ThequestionBatch { get; set; }
public List<Question> listQuestion { get; set; }
public List<ResponseTag> listResponseTag { get; set; }
}
Controller
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult submit_Questionaire(VM_Questionaire vm_question)

if (ModelState.IsValid)
{
Console.Write(Newtonsoft.Json.JsonConvert.SerializeObject(vm_question));
}
return View("Index");
}

First object getting value, but the list getting null.

#Html.DisplayFor() will not post values. You need to use #Html.HiddenFor() along with #Html.DisplayFor(). Refer: Html.DisplayFor not posting values to controller in ASP.NET MVC 3

if you're not passing any type of data then make your data as a hidden field and after that you will received your data at your respective controller.
Thanks.

how to properly fix MVVM scaffolding issue with duplicate name tag? (ASP Core 2.2)

Here's my problem, I have a Book that contains List<Page> that contains List<Line> and I'm trying to create a view that will edit my book. This view contains all the lines from the book. I've made an MVVM for List<Page> that calls smaller MVVM for List<Line>. The problem is that MVVM is not counting all Line as one single form, so this happens:
<form>
<h1>Page one</h1>
<input type="hidden" name="[0].lineContent" value=""/>
<input type="hidden" name="[1].lineContent" value=""/>
<h1>Page one</h1>
<input type="hidden" name="[0].lineContent" value=""/>
<input type="hidden" name="[1].lineContent" value=""/>
<input type="hidden" name="[2].lineContent" value=""/>
</form>
Each time my for loop for page iterates, my for loops in lines get reset to 0, this creates duplicate name entries.
There are multiple ways to correct this, the easiest:
Build input by hand with unique name id instead of using HTML helpers
My question is the following: how can I achieve a clean razor that can be reused, and that will not duplicate name entries in my form?
UPDATE:
Context:
Just like the book exemple up, my models have the same structure.
in my case I have a Submission that contains a list of Section that contains a list of SubSection that contains a list of SubmissionLine.
Here's my main view:
#model
QuotingPlus.Models.Submission
#{
ViewData["Title"] = "Edit";
}

<td>#Html.CheckBoxFor(x => Model[indexLine].IsDisplayed, new {#class = "checkbox"}).
</td>
</tr>
}
I only want to know how I can keep this structure with MVVM and avoid the input name duplicate issue?
RE-UPDATE:
I'm not quite sure why this would be useful since I get name duplicate input, but here's my save action:
[HttpPost]
[ValidateAntiForgeryToken]
[Authorize(Roles = "Admin, SuperAdmin, Employe")]
public ActionResult Edit(int id, Submission submission, [FromForm] List<SubmissionLine> lines)
{
var test = Request.Form;
if (id != submission.IdSubmission)
{
return NotFound();
}
if (ModelState.IsValid)
{
SubmissionUpdateHelper.SaveSubmissionModifications(_context, submission, lines);
return RedirectToAction(nameof(Index));
}
ViewData["IdProject"] = new SelectList(_context.Project, "IdProject", "Name", submission.IdProject);
ViewData["IdTypeSubmission"] = new SelectList(_context.TypeSubmission, "IdTypeSubmission",
"TypeSubmission1", submission.IdTypeSubmission);
return View(submission);
}

For showing sub-list properties in View, Try code below:
<div class="row">
<div class="col-md-4">
<form asp-action="Edit">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<input type="hidden" asp-for="Id" />
<div class="form-group">
<label asp-for="BookName" class="control-label"></label>
<input asp-for="BookName" class="form-control" />
<span asp-validation-for="BookName" class="text-danger"></span>
</div>
<div class="form-group">
#for (int i = 0; i < Model.Pages.Count; i++)
{
<div class="form-group">
<label asp-for="Pages[i].PageName" class="control-label"></label>
<input asp-for="Pages[i].PageName" class="form-control" />
<span asp-validation-for="Pages[i].PageName" class="text-danger"></span>
</div>
<div class="form-group">
#for (int j = 0; j < Model.Pages[i].Lines.Count; j++)
{
<div class="form-group">
<label asp-for="Pages[i].Lines[j].LineContent" class="control-label"></label>
<input asp-for="Pages[i].Lines[j].LineContent" class="form-control" />
<span asp-validation-for="Pages[i].Lines[j].LineContent" class="text-danger"></span>
</div>
}
</div>
}
</div>
<div class="form-group">
<input type="submit" value="Save" class="btn btn-primary" />
</div>
</form>
</div>
</div>

Finally, I've just added the input by hand so I could keep my MVVM pattern. I've also used an increment variable in TempData so I could keep track of the input
in Edit.cshtml
#{
TempData["submissionLineCount"] = 0;
}
here's the new version of SubmissionLineEditor.cshtml
#model List<SubmissionLine>
#for (var indexLine = 0; indexLine < Model.Count; indexLine++)
{
<tr>
<input name="[#(TempData["submissionLineCount"])].IdSubmissionLine" value="#(Model[indexLine].IdSubmissionLine)" type="hidden"/>
<input name="[#(TempData["submissionLineCount"])].IdArticle" value="#(Model[indexLine].IdArticle)" type="hidden"/>
<input name="[#(TempData["submissionLineCount"])].IdSubmissionSubSection" value="#(Model[indexLine].IdSubmissionSubSection)" type="hidden"/>
<td>#TempData["submissionLineCount"]</td>
<td>
<input name="[#(TempData["submissionLineCount"])].Quantity" value="#(Model[indexLine].Quantity)" type="number" step="0.5" min="0"/>
</td>
<td>#Model[indexLine].IdArticleNavigation.Designation</td>
<td>#Model[indexLine].TotalMaterial</td>
<td>#Model[indexLine].IdArticleNavigation.UnitPriceMaterial</td>
<td>#Model[indexLine].TotalSubContractor</td>
<td>#Model[indexLine].IdArticleNavigation.UnitPriceSubContractor</td>
<td>#Model[indexLine].TotalWorkforce</td>
<td>#Model[indexLine].IdArticleNavigation.UnitPriceWorkforce</td>
<td>
<input type="checkbox" name="[#(TempData["submissionLineCount"])].IsDisplayed" class="checkbox" value="#(Model[indexLine].IsDisplayed)"/>
</td>
</tr>
{
TempData["submissionLineCount"] = (Convert.ToInt32(TempData["submissionLineCount"]) + 1);
}
}
This is clearly not the best way, I hope there will be more documentation on how to apply MVVM in AspNet.Core in the future...
If this answer gets deprecated, make sure to post your own!

ASP.NET Core 2.1 Unobtrusive Ajax Validation Not Working With Partial View Form Swap

I've spent several hours combing Stackoverflow and other sites trying everyone's solutions with no luck so far. I'm sure I've missed something, but I can't see it. Hopefully you can point me to a fix.
I have an initial form inside a partial view that is rendered into a parent view whose validation works fine. Once the form is submitted via Ajax replace, I return either a login or registration partial view with a new form in the response. This second form will not display the model validation errors when an incomplete form is submitted and the same partial view is returned.
Thanks in advance for any tips you can offer to bring an end to this insanity!

I have updated the parent page (index.cshtml) to the following and it still doesn't display the messages.

</div>
</div>
#section Scripts
{
#{ await Html.RenderPartialAsync("_ValidationScriptsPartial"); }
}

The problem was that I had not used the asp-for tag helpers. Those helpers are responsible for generating the data-* attributes needed by the unobtrusive validation parser. Once I started using them it started working. Thank you to everyone who tried to help.

if (!ModelState.IsValid)

pretty sure this violates pathing

Showing the data of the right side of the TimeLine

How can I show the description Data on the left or the right side of the timeline acording of it Candidate.Saving result?
If it's Candidate.Saving == true it should be on the left, if it's Candidate.Saving==false it should be on the right side of the time line.
I will shou here my candidate Model And my View.
public class Candidate : BaseEntity
{
public int Id { get; set; }
public string Name { get; set; }
public int Number { get; set; }
public string ProfileText { get; set; }
public Byte[] CV { get; set; }
public string CVNAME { get; set; }
public List<Profile> ProfileList { get; set; }
public String Description { get; set; }
public Boolean Saving { get; set; }
public string Title { get; set; }
public DateTime DateOfDescription { get; set; }
}
Here is my view:
#model HCCBPOHR.Data.Candidate
#{
ViewData["Title"] = "CandidateHistory";

What I've tried to do:
I have tried to make a foreach method where the side depends of the Candidate.Saving, But the result was this:
I have managed to fix it.
This is how I did It:

<div class="panel-body">

</ul>
}
</div>
</div>
I only have on doubt right now, to be able to add more than one Description for the candidate I should Create a list off Descriptions
and do a foreach method in the view right?
Right now my controller looks like this:
public IActionResult CandidateHistory(int Id)
{
using (var applicationcontext = new ApplicationContext())
{
var candidate = applicationcontext.Candidates.Where(s => s.Id.Equals(Id)).SingleOrDefault();
if (candidate == null)
{
return NotFound();
}
Candidate candidates = new Candidate();
candidates.DescriptionList.Add(candidate);
candidates.DescriptionList.Add(new Candidate { Description = candidate.Description });
candidates.DescriptionList.Add(new Candidate { Title = candidate.Title });
candidates.DescriptionList.Add(new Candidate { DateOfDescription = candidate.DateOfDescription });
candidates.DescriptionList.Add(new Candidate { Saving = candidate.Saving });
applicationcontext.Candidates.Add(candidates);
return View();
}
}
[HttpPost, ActionName("CandidateHistory")]
[ValidateAntiForgeryToken]
public async Task<IActionResult> CandidateHistoryPost(int? id, Candidate candidatelist)
{
if (id == null)
{
return NotFound();
}
using (var context = new ApplicationContext())
{
var candidateUpdate = await context.Candidates.SingleOrDefaultAsync(s => s.Id == id);
if (await TryUpdateModelAsync<Candidate>(candidateUpdate, "", s => s.Description, s => s.Title, s => s.DateOfDescription, s => s.Saving))
{
try
{
await context.SaveChangesAsync();
return RedirectToAction(nameof(CandidateHistory));
}
catch (DbUpdateException /* ex */)
{
//Log the error (uncomment ex variable name and write a log.)
ModelState.AddModelError("", "Unable to save changes. " +
"Try again, and if the problem persists, " +
"see your system administrator.");
}
}
return View(candidateUpdate);
}
}
I'm trying to output an Candidate.DescriptionList to the CandidateHistory View so that way I can save into that list all the descriptions, description title, date and "saving", so i can do a foreach method to output all the description of that user.
But now I have this error:
System.NullReferenceException: 'Object reference not set to an instance of an object.
HCCBPOHR.Data.Candidate.DescriptionList.get returned null.`

I have managed to fix it.
This is how I did It:
<div class="panel panel-default">
<div class="panel-heading">
<i class="fa fa-clock-o fa-fw"></i> History Of #Model.Name
</div>
<div class="panel-body">
#if (Model.Saving == true)

How can i use Remote Attribute in Mvc 5?

I developing business application in ASP MVC 5. I was trying to use Remote attribute but its not working.
Metadata class - where i put attribute
[MetadataType(typeof(Departmanmetadata))]
public partial class DepartmanTable
{
}
public class Departmanmetadata
{
[Key]
[DisplayName("Deparman No")]
public int DepartmanID { get; set; }
[Required(ErrorMessage = "Bu alan boş bırakılamaz!")]
[StringLength(50, MinimumLength = 2, ErrorMessage = "Lütfen 2 ile 50 karakter arasında veri giriniz!")]
[DisplayName("Departman Adı")]
[Remote("IsNameAvaible", "Departman", ErrorMessage = "Sistemde zaten var!")]
public string DepartmanName { get; set; }
}
Controller
public JsonResult IsNameAvaible(string name)
{
return Json(!db.DepartmanTable.Any(a => a.DepartmanName == name), JsonRequestBehavior.AllowGet);
}

Create button doesn't working.
I think Scripts is the problem. Here the scripts.
<script src="~/scripts/jquery-1.10.2.min.js"></script>
<script src="~/scripts/jquery.validate.unobtrusive.min.js"></script>
<script src="~/scripts/jquery.validate.min.js"></script>
What might be the issue?

The property you apply the attribute to is named DepartmanName and generates the following html
<input type="text" name="DepartmanName" ..... />
which means you controller method must have a matching parameter. Change it to
public JsonResult IsNameAvaible(string departmanName)
{
....
}
