Value of parameters is null - c#

The below code displays list of countries with checkbox for each. The intend is to save which checkbox was checked.
But when the submit button is clicked, in the method
ActionResult Index(UserModel newmodel) in the newmodel, the value of parameters SelectedSecurityGroup, SelectedSecurityObject and SecurityGroups is null.
Any idea what is wrong with this code?
In UserModel.cs
public class UserModel
{
public string SelectedSecurityGroup { get; set; }
public string SelectedSecurityObject { get; set; }
[DisplayName("Security Group")]
public virtual ICollection<SecurityGroup> SecurityGroups { get; set; }
}
public class SecurityGroup
{
public int Id { get; set; }
public string SecurityGroupName { get; set; }
public bool Active { get; set; }
}
In UserController.cs
[HttpGet]
public ActionResult Index()
{
UserModel objUserModel = new UserModel();
List<SecurityGroup> lstSecurityGroup = FillViewBag();
objUserModel.SecurityGroups = lstSecurityGroup;
return View(objUserModel);
}
[HttpPost]
public ActionResult Index(UserModel newmodel)
{
string strtest = "";
//Code to save data
return View(newmodel);
}
private List<SecurityGroup> FillViewBag(UserModel model = null)
{
List<SecurityGroup> lstSecurityGroup = new List<SecurityGroup>();
lstSecurityGroup.Add(new SecurityGroup { Id = 1, SecurityGroupName = "India", Active = true });
lstSecurityGroup.Add(new SecurityGroup { Id = 2, SecurityGroupName = "USA", Active = true });
lstSecurityGroup.Add(new SecurityGroup { Id = 3, SecurityGroupName = "Pakistan", Active = false });
lstSecurityGroup.Add(new SecurityGroup { Id = 4, SecurityGroupName = "Nepal", Active = false });
return lstSecurityGroup;
}

Finally got it working. Below is the corrected code:
In SecurityListsView.cshtml
#model Example.User.Web.Models.UserModel
#using (Html.BeginForm("Index", "User", "POST"))
{

#{ int i = 0; }
#foreach (var newitem in Model.SecurityGroups)

#Html.HiddenFor(model => model.SecurityGroups[i].Id, "Value")
</td>
<td>
#Html.DisplayFor(model => model.SecurityGroups[i].SecurityGroupName)
</tr>
i++;
}
</table>
<input type="submit" name="btn1" value="Save" />
}
Hope it helps someone! :)

Passing ID from View to Controller (ASP.NET)

I'm getting the following error:
System.NullReferenceException: 'Object reference not set to an instance of an object.'
Microsoft.AspNetCore.Mvc.Razor.RazorPage.Model.get returned null.
I'm trying to pass an Id from a view to a controller HttpPost action method.
Here is my code:
Controller:
public class HomeController : Controller
{
...
[Authorize]
public IActionResult List()
{
var currentUserId = User.FindFirst(ClaimTypes.NameIdentifier).Value;
var currentCars = db.Cars.Where(x => x.CreatedByUserId == currentUserId)
.Select( x => new CarsListViewModel
{
CarId = x.Id,
CreatedOn = x.CreatedOn,
CreatedByUserId = x.CreatedByUserId,
CreatedByUserName = x.CreatedByUserName,
Firstname = x.PrimaryData.Firstname,
Lastname = x.PrimaryData.Lastname
}).
ToList();
return View(currentCars);
}
[HttpPost]
[Authorize]
[ValidateAntiForgeryToken]
public IActionResult List(int carId)
{
var Car = db.Cars.FirstOrDefault(x => x.Id == carId);
db.Cars.Remove(Car);
db.SaveChanges();
return View();
}
ViewModel:
public class CarListViewModel
{
public int CarId { get; set; }
public DateTime CreatedOn { get; set; }
public string CreatedByUserId { get; set; }
public string CreatedByUserName { get; set; }
public string Firstname { get; set; }
public string Lastname { get; set; }
}
}
View (List.cshtml):
#model List<CVBuilder.ViewModels.CarListViewModel>
#{
ViewData["Title"] = "List of current cars";
}
<div class="col-md-10 offset-md-1">
<table class="table table-hover text-nowrap">
<thead>
...
</thead>
<tbody>
#for (int i = 0; i < Model.Count; i++)
{
<tr>
<td>#Model[i].CreatedOn</td>
<td>#Model[i].CreatedByUserName</td>
<td>#Model[i].Firstname</td>
<td>#Model[i].Lastname</td>
<td>
<form method="post">
<input type="hidden" name="carId" value="#Model[i].CarId" />
<button type="submit" class="btn btn-danger btn-sm">Delete</button>
</form>
</td>
</tr>
}
</tbody>
</table>
#if (Model.Count == 0)
{
<div class="text-center"><p>No cars created.</p></div>
}
</div>

try it:
public IActionResult List([FromForm]int carId){
// return View(); remove
return RedirectToAction("List")
}

You can try this to pass a particular model id from view to controller in MVC
<button href="#Url.Action("List", "ControllerName", new { carId = #Model[i].CarId},null)" button>

ASP.NET MVC Get checkstate from looped, bound checkboxes

in my journey of learning ASP.NET MVC I encounterd another difficulty:
I'm trying to POST a form with 3 checkboxes, the checkboxes are looped onto the form according to a bound PresentationModel.
I don't know what to fill in at the "asp-for" tag-helpers for the checkboxes in the view so they pass a boolean to the "Create()" ActionResult in the controller and to show the values in the "Overview" View.
Currently it passes NULL for al of them, the other aproaches I tried always resulted in an "InvalidCastException" as it has to be a boolean not an "int[]".

}
public ActionResult Create(PMRegistration pm)
{
if (ModelState.IsValid)
{
return View("Overview", pm);
}
else
{

With HTML-helpers:
#for (int i = 0; i < Model.Devices.Count; i++)

#Html.CheckBoxFor(m => Model.Devices[i].CheckState)

c# object created in main view passed to partial view empty

C#, .Net 4.5, MVC 5
Referring to XX1 and XX2 below (Main View):
The object is initialized in the main controller. (Both the header and the Detial.)
I have added breakpoints at both XX1 and XX2 to confirm that that the initialized values are still there.
No problem with XX1. The initialized values are there and it is
passed to and received by the controller.
XX2 have a problem. The initialized values are still there and is
passed to, but a null object is somehow received by, the controller.
Why do the controller for the detail not pick up the passed parameters for it.
Model:
public class SampleNonRoutine
{
public HeaderNonRoutine SampleHeader { get; set; }
public List<DetailNonRoutine> SampleDetail { get; set; }
public string Comments { get; set; }
}
public class HeaderNonRoutine
{
public string Division { get; set; }
public string Name { get; set; }
public string Telephone { get; set; }
[DisplayName("Sample Title")]
public string SampleTitle { get; set; }
[DisplayName("Retain Sample for")]
public int RetainSample { get; set; }
}
public class DetailNonRoutine
{
public int ID { get; set; }
[DisplayName("Sample Reference #")]
public string SampleReference { get; set; }
[DisplayName("Sample Test")]
public string SamplesTested { get; set; }
[DisplayName("Sample Assays")]
public string SampleAssays { get; set; }
}
Controller:
For Parent View
public ActionResult NonRoutineSamples(string SaveSend)
{
SampleNonRoutine sample = new SampleNonRoutine();
sample.SampleHeader = new HeaderNonRoutine();
sample.SampleDetail = new List<DetailNonRoutine>();
sample.Comments = "Toets";
for (int i = 0; i < 10; i++)
{
sample.SampleDetail.Add(new DetailNonRoutine { ID = i + 1, SampleReference = "", SamplesTested = "", SampleAssays = "" });
}
return View(sample);
}
For Partial Views:
Header (Partial View):
public ActionResult _HeaderNonRoutineSamples(HeaderNonRoutine model)
{
//...some code
PersonDetail pDetail = _db.ListPerson(_MePerson.First().Number.ToString());
model.Name = pDetail.Name + " " + pDetail.Surname;
model.Telephone = pDetail.PhoneWork;
model.Division = pDetail.Division;
model.RetainSample = 30;
return PartialView(model);
}
Detail:
public ActionResult _DetailNonRoutineSamples(List<DetailNonRoutine> model)
{
return PartialView(model);
}
Views:
Main
#model LaboratorySampleRegistration.Models.SampleNonRoutine
#{
ViewBag.Title = "NonRoutineSamples";
}
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<h4>Non-Routine Samples</h4>

How can I post a list of items in MVC

I have a simple form with a list of items in it and I'd like to post them to the controller but funny thing is I just cant. Everything else goes through properly except the list. I checked the ajax call in firebug and the post values are there like this:
Answers[0].IsMissing False
Answers[0].Text Ja
Answers[0].Value 0
Answers[1].IsMissing False
Answers[1].Text Nein
Answers[1].Value 1
Id 1cd14b08-ce3b-4671-8cf8-1bcf69f12b2d
Name Ja/Nein
I have an AnwserScheme class with the following properties:
public string Name { get; set; }
public bool IsMissing { get; set; }
public List<AnswerDisplayItem> Answers { get; set; }
public AnswerScheme()
{
Answers = new List<AnswerDisplayItem>();
}
I have this view code:
#for (int i = 0; i < Model.Answers.Count; i++) {
<tr>
<td>
#Html.HiddenFor(model => Model.Answers[i].IsMissing)
#Html.TextBoxFor(model => Model.Answers[i].Value,
new { #class = "inputValue" })
</td>
<td>
#Html.TextBoxFor(model => Model.Answers[i].Text,
new { #class = "inputAnswer" })
</td>
<td>
<span class="span-delete"
data-answer-scheme-id="#Model.Id"
data-answer-id="#Model.Answers[i].Id" >x</span>
</td>
</tr>
}
I have this piece of ajax code that is responsible for posting:
$.ajax({
url: "/AnswerScheme/AddAnswer",
type: "post",
data: $("#formAnswerScheme").serialize(),
success: function (data) {
console.log(data);
$("#divAnswerSchemeContainer").html(data);
}
});
I have an add answer action in my controller:
[HttpPost]
public PartialViewResult AddAnswer(AnswerScheme answerScheme)
{
...some logic comes here
}
So in the end the controller recieves the model, but only the simple properties, not the list. Any help would be greatly appreciated! cheers.

I wish I could see more of your classes and code, because you don't have something set up right.
I recreated something from what you did provide, which works. I created an MVC 3 project for this sample.

And controller is pretty much the same.

You can do like this create model
public class ApplicationInfo
{
public List<ApplicationAccessRoles> ApplAccessRoleInfo { get; set; }
}
public class ApplicationAccessRoles
{
public int app_access_role_key { get; set; }
public int app_key { get; set; }
public string access_role { get; set; }
public bool inactive { get; set; }
}
put it in view
<div class="step-pane" id="step3">
<div class="form-horizontal" style="vertical-align:central;margin-left:150px">
<table id="RolesDetails" cellpadding="0" cellspacing="0" class="data_table">
<tr class="dataheader">
<td class="width5">
#Html.HiddenFor(m => m.app_access_role_key)
</td>
<td class="width200">
Access Roles Name
</td>
<td class="width10">
Inactive
</td>
</tr>
#if (Model.ApplAccessRoleInfo.Count!= 0)
{
var chk = Model.ApplAccessRoleInfo.Count;
for (int a = 0; a < Model.ApplAccessRoleInfo.Count; a++)
{
<tr class="exp_col_header top_border_nil">
#if ((chk - 1) == a)
{
<td></td>
}
else
{
<td></td>
}
<td>
#Html.HiddenFor(m => m.ApplAccessRoleInfo[a].app_access_role_key)
#Html.EditorFor(m => m.ApplAccessRoleInfo[a].access_role)
</td>
<td>
#Html.CheckBox("ApplTeamAccessInfo[" + a.ToString() + "].inactive", false, new { #class = "check-box"})
</td>
</tr>
}
}
else
{
<tr class="exp_col_header top_border_nil">
<td>
</td>
<td>
#*#Html.EditorFor(model => model.access_role)*#
#*#Html.EditorFor(m => m.ApplAccessRoleInfo[0].access_role)*#
#Html.EditorFor(model=>model.access_role)
</td>
<td>
#Html.CheckBoxFor(model => model.inactive)
</td>
</tr>
}
</table>
</div>
</div>
In Controller
var main = (from a in db.mas_app_access_roles
where a.app_key == AppInfo.app_key
select new ApplicationAccessRoles
{
app_access_role_key = a.app_access_role_key,
access_role = a.access_role,
inactive = a.inactive,
}).ToList();
access = main;
AppInfo.ApplAccessRoleInfo = access;
ViewBag.check = access;
return View(AppInfo);

The problem is with the name/id attribute of your text boxes and other input controls. You can use editor templates to make things seamless and reusable.. Another example here.
But if you still want to loop through things, your loop has to look something in these examples here or here.

Try changing either the controller parameter name to "answers" or the property name to AnswerScheme and if the partial controller in your post is supposed to be recieving the list then change the type to:
List<AnswerScheme> answers

model is null when trying to get data from view to controller

I have a module which send data from controller to view. it has multiple rows and it shows correctly as i wanted. now after making some changes by user i am trying again to save changes in database with the help of actionresult. but when i try to fetch values it say my model is empty/null but it's not ...i am not getting what is the issue...Thanks in advance...

var context = new ndCorp_SiteEntities();

Your checkboxes are named chk1 and chk2, but your field is called chkBillboard. When you post your value, it uses the names of the input fields to match up the field names in your model.
I suggest using a helper, which makes sure you have the correct format.
#Html.CheckBoxFor(x => item.chkBillboard, new { #class="myCheckbox" })
