update session data from ViewModel

here I updated my quantity. how I will use or inject this updated quantity?
[HttpGet]
public ActionResult Details(int? id)
{
ViewBag.product = _db.Spray.ToList();
if (id == null)

return NotFound();
}
var hi = _db.Spray.Include(c => c.ProductTypes).FirstOrDefault(c => c.Id == id);
ProductVm product = new ProductVm
{

above view, the list of item session data can not pick my updated quantity. how I solved this problem. I am facing problem in order of the value of the quantity.
I am beginner, please anyone help.

Here is a demo to show how to pass List to controller with ajax：

Model not returning values to controller from dynamically added content?

I have schedule times that can be added dynamically from code behind using Ajax. The user can click an add button and jquery Ajax call should add another set of fields to add a schedule time. From some reason, my model is not returning any values to the controller when I click save.
I've tried using a different model that also includes Date, Start Time and End Time, but the returns no values as well. It seems like the values from the fields are not being posted from the form.
The HTML form
<form asp-action="SetSchedule" asp-controller="Admin" method="post" id="addEventForm">
<table id="scheduleTable">
<thead>
<tr>
<th>Date</th>
<th>Start Time</th>
<th>End Time</th>
<th></th>
</tr>
</thead>
<tbody></tbody>
</table>
<br />
<button id="addScheduleButton" type="button">Add Schedule Time</button>
<button id="savePendingButton" type="submit" style="margin-left:1em" hidden>Save</button>
</form>
Controller:
[HttpPost]
[Authorize(Roles = "Admin")]
public IActionResult SetSchedule(ScheduleViewModel model)
{
_adminManager.SetInterviewSchedule(model);
return RedirectToAction(nameof(ViewSchedule));
}
Model:
public class ScheduleViewModel
{
public List<Schedule> ScheduleItems { get; set; } = new List<Schedule>();
//public InterviewInfoApplicationViewModel InterviewInfo { get; set; } = new InterviewInfoApplicationViewModel();
}
public class Schedule
{
public int Id { get; set; }
public DateTime DateAvailable { get; set; }
[Required]
public DateTime StartTime { get; set; }
[Required]
public DateTime EndTime { get; set; }
public bool IsSelected { get; internal set; }
}
Fields to append on ajax call page:
#model Ambassadors.Managers.ViewModels.Admin.Schedule
#{
string rowClass = "pendingScheduleRow";
}
<tr class="#rowClass" style="margin-top:1em">
<td>
#Html.ValidationMessageFor(x => x.DateAvailable)
<input type="text" asp-for="DateAvailable" class="datepickerInput" />
</td>
<td>
#Html.ValidationMessageFor(x => x.StartTime)
<input type="text" asp-for="StartTime" class="timepickerInput" />
</td>
<td>
#Html.ValidationMessageFor(x => x.EndTime)
<input type="text" asp-for="EndTime" class="timepickerInput" />
</td>
<td>
<a class="tooltip deletePendingSchedule" title="Remove Schedule Time" style="cursor:pointer">
<span class="wdn-icon-cancel" aria-hidden="true"></span><span class="wdn-text-hidden">cancel icon</span>
</a>
</td>
</tr>
Script:
require(['jquery', 'jqueryui'], function ($, jqueryui) {
$(function () {
$('body').on('focus', ".datepickerInput", function () {
$(this).datepicker({
controlType: "select",
});
});
$('body').on('focus', ".timepickerInput", function () {
$(this).timepicker({
timeFormat: "hh:mm tt",
interval: 5,
dropdown: true,
scrollbar: true
});
});
$("#addScheduleButton").click(function () {
var nextIndex = $(".pendingScheduleRow").length;
$.ajax({
url: "/Admin/AddScheduleItem",
type: 'POST',
data: {
index: nextIndex
},
success: function (results) {
$("table#scheduleTable tbody").append(results);
$("#savePendingButton").show();
}
});
});
$("#scheduleTable").on("click", ".deletePendingSchedule", function () {
var closestRow = $(this).closest("tr");
$(closestRow).hide();
var visibleRows = $(".pendingScheduleRow:visible").length;
if (visibleRows === 0) {
$("#savePendingButton").hide();
}
});
});
});
Model should return DateAvailable, StartTime and EndTimes to the controller.

Your action receives model type of ScheduleViewModel who has a property of List<Schedule> while your view asp-for="DateAvailable" neither bind to ScheduleViewModel nor bind to List<Schedule>.
Refer to my below demo:
1.AddScheduleItem action to return index to partial view
public IActionResult AddScheduleItem(string index)
{
var myViewData = new ViewDataDictionary(new Microsoft.AspNetCore.Mvc.ModelBinding.EmptyModelMetadataProvider(), new Microsoft.AspNetCore.Mvc.ModelBinding.ModelStateDictionary())
{
{ "index", index }
};
PartialViewResult result = new PartialViewResult()
{
ViewName = "YourPartialViewName",
ViewData = myViewData,
};
return result;
}
2.YourPartailView:
#model ScheduleViewModel
#{
string rowClass = "pendingScheduleRow";
int index = Int32.Parse(#ViewData["index"].ToString());
}
<tr class="#rowClass" style="margin-top:1em">
<td>
#Html.ValidationMessageFor(x => x.ScheduleItems[index].DateAvailable)
<input asp-for="ScheduleItems[index].DateAvailable" class="datepickerInput" />
</td>
<td>
#Html.ValidationMessageFor(x => x.ScheduleItems[index].StartTime)
<input asp-for="ScheduleItems[index].StartTime" class="timepickerInput" />
</td>
<td>
#Html.ValidationMessageFor(x => x.ScheduleItems[index].EndTime)
<input asp-for="ScheduleItems[index].EndTime" class="timepickerInput" />
</td>
<td>
<a class="tooltip deletePendingSchedule" title="Remove Schedule Time" style="cursor:pointer">
<span class="wdn-icon-cancel" aria-hidden="true"></span><span class="wdn-text-hidden">cancel icon</span>
</a>
</td>
</tr>
#{ await Html.RenderPartialAsync("_ValidationScriptsPartial");}

ASP NET MVC - Form in view

i have a problem in my asp.net view. I'v got a foreach loop, and i can't put my first iteration into my form.
That's the code:
<div id="#item.Name" class="tab-pane fade in active">
<div class="row">
#{int i = 0;}
#foreach (var prod in item.Products.Where(p => p.Type_Id == item.Id && p.IsDeleted != true))
{
using (Html.BeginForm("AddOrderRow", "Orders", new { enctype = "multipart/form-data", #class = "form-inline" }))
{
<input type="hidden" value="#ViewBag.orderId" name="Order_Id" />
<input type="hidden" value="#prod.Id" name="ProductID" />
<input type="hidden" value="#prod.Price" name="Price" />
<div class="col-sm-3" style="padding-bottom:20px">
<div align="center">
<button style="background-color:transparent; border-color:transparent">
<img class="img-responsive" src='#VirtualPathUtility.ToAbsolute(String.Format("{0}/{1}", System.Configuration.ConfigurationManager.AppSettings["ProdUploadPath"], prod.Image))' style="max-height: 100px" data-toggle="tooltip" title="#prod.Name">
</button>
</div>
</div>
if (i % 4 == 3)
{
#:</div><div class="row">
}
i++;
}
}
</div>
</div>
And that's how it look:
As you can see, only first div into first row is out of my form.

my suggest if you want save list, use save list not iteration form
example controller here;s the one when i learn mvc hahaha
public ActionResult Create(int? area, string now, string search, string message)

Pass dynamic model to controller

I have table which is filled with some data, when I click "addTemplate" in my controller I don't get any data from table.
Here is my index.cshtml
#model ReportGenerator.WebUI.Models.FieldViewModel
#{
var list = #Model.IEnumerableField.GroupBy(item => item.TemplateName).ToList();
}
#using (Html.BeginForm("addTemplate", "TemplateField", FormMethod.Post))
{
<div class="form-group">
<div class="input-group">
<label class="label label-default">Nazwa szablonu*</label>
#Html.TextBoxFor(m => m.field.TemplateName, new { #class = "form-control" })
<br /><br />
</div>
</div>
<table id="sort" class="table">
<thead>
<tr>
<th>Nazwa kolumny z BD*</th>
<th>Długość rekordu*</th>
<th>Nazwa kolumny wyświetlana</th>
<th>Format*</th>
</tr>
</thead>
<tbody id="tblsort">
#for (var i = 0; i < Model.listOfFormats(Model.field.TemplateName).ColumnNamesDB.Count; i++)
{
<tr>
<td>#Html.TextBoxFor(m => Model.listOfFormats(Model.field.TemplateName).ColumnNamesDB[i], new { #class = "form-control" })</td>
<td>#Html.TextBoxFor(m => Model.listOfFormats(Model.field.TemplateName).LengthColumns[i], new { #class = "form-control" })</td>
<td>#Html.TextBoxFor(m => Model.listOfFormats(Model.field.TemplateName).ColumnNamesUser[i], new { #class = "form-control" })</td>
<td>#Html.DropDownListFor(m => Model.listOfFormats(Model.field.TemplateName).Formats[i], new SelectList(Model.formatFieldValues, "Value", "Text"), Model.listOfFormats(Model.field.TemplateName).Formats[i], new { #class = "form-control" })</td>
</tr>
}
</tbody>
</table>
<div id="hiddenHtml" style="display:none;">
#Html.DropDownList("FormatFieldName", new SelectList(Model.formatFieldValues, "Value", "Text"), "Domyślny", new { #class = "form-control" })
</div>
<button class="btn btn-success" type="button" id="addRow" style="float: right;"><span class="glyphicon glyphicon-plus" id="addRow"></span></button>

</div>
<br /> <br />
#Html.ValidationSummary()
<h1 style="color:#ViewBag.color">#ViewBag.Info</h1>
}
Here is my model
public class FieldViewModel
{
public TemplateField field { get; set; }
public IEnumerable<TemplateField> IEnumerableField;
public Fields fieldObj {get;set;}
public Fields listOfFormats(string nameTemplate)
{
Fields obj = new Fields();
var items = IEnumerableField.Where(i => i.TemplateName == nameTemplate).ToList();
if (items != null)
{
foreach (var x in items)
{
obj.ColumnNamesDB.Add(x.ColumnNameDB);
obj.Formats.Add(x.Format);
obj.LengthColumns.Add(x.Length.ToString());
obj.ColumnNamesUser.Add(x.ColumnNameUser);
}
}
return obj;
}
}
and finally my controller method
public ActionResult addTemplate(FieldViewModel model)
{
return ? // model is empty, there is nothing...
}
I think that I made some mistake in Model, can someone look at this?
Thanks for any help!
EDIT:
Here is Fields class:
public class Fields
{
public List<string> ColumnNamesDB = new List<string>();
public List<string> LengthColumns = new List<string>();
public List<string> Formats = new List<string>();
public List<string> ColumnNamesUser = new List<string>();
}
and TemplateField cass
public class TemplateField
{
[Key]
public int FieldId { get; set; }
[Required(ErrorMessage = "Proszę podać nazwę kolumny z bazy danych.")]
public string ColumnNameDB { get; set; }
[Required(ErrorMessage = "Proszę podać długość rekordu.")]
public int Length { get; set; }
public string Format { get; set; }
[Required(ErrorMessage = "Proszę podać nazwę szablonu.")]
public string TemplateName { get; set; }
[Required(ErrorMessage = "Proszę podać nazwę kolumny jaka będzie wyświetlana.")]
public string ColumnNameUser { get; set; }
}
EDIT
Ok I have made a lot of miastakes here so this question don't have an answer I think.

MVC Enum Model Binding in For Loop

I have an MVC 5 app where I am using a for loop so I can bind a collection when passing back to the controller. This works fine for all my properties except for the one that is based on a DropDownFor type.
The problem is the name of the property is not getting set to "product.[0].TypeOfSubscription.
I have tried 3 different ways: The first 2 method end up with a name of [0].TypeOfSubscription and the 3rd one does have the correct name product[0].TypeOfSubscription but there is no binding occuring when I pass it back to the controller.
I think the problem is that the 3rd option is binding but because it is hidden it is not getting the selected value assigned.
#Html.EnumDropDownListFor(modelItem => Model[i].TypeOfSubscription)
#Html.EnumDropDownListFor(modelItem => Model[i].TypeOfSubscription,
new { name = "product[" + #i + "].TypeOfSubscription"})
#Html.Hidden("product[" + #i + "].TypeOfSubscription",
Model[i].TypeOfSubscription)
Model
public class VmStoreProducts
{
public VmStoreProducts()
{
NoOfUsers = 1;
}
public enum SubscriptionType
{
Monthly,
Annual
}
public int MojitoProductId { get; set; }
[Display(Name = "Category")]
public string ProductCategory { get; set; }
public virtual string Name { get; set; }
public string Description { get; set; }
[Display(Name = "Image")]
public byte[] ImageData { get; set; }
[Display(Name = "Type of Subscription")]
public SubscriptionType TypeOfSubscription { get; set; }
public decimal Price { get; set; }
[Display(Name = "No. of Users")]
public int NoOfUsers { get; set; }
[Display(Name = "Total Price")]
[DisplayFormat(DataFormatString = "{0:C}")]
public decimal TotalPrice { get; set; }

Controller Method
public ActionResult AddToCart(List<VmStoreProducts> product, string returnUrl)
{
ShoppingCart cartObjects = (Session["CartObjects"] as ShoppingCart) ?? new ShoppingCart();
Session["CartObjects"] = cartObjects;
foreach (var item in product)
{
if (item.NoOfUsers > 0)
{
cartObjects.AddItem(item);
}
}
return RedirectToAction("Index", new { returnUrl });
}

Move the definition of the enum outside the VmStoreProducts class
public enum SubscriptionType
{
Monthly,
Annual
}
public class VmStoreProducts
{
public VmStoreProducts()
{
NoOfUsers = 1;
}
public int MojitoProductId { get; set; }
....
}
The for loop will name the selects
[0].TypeOfSubscription
[1].TypeOfSubscription
....
which will correctly bind on postback (assuming your action method is public ActionResult AddToCart(IEnumerable<VmStoreProducts> products) {...
Also, do not use
#Html.TextBox("product[" + #i + "].Name", Model[i].Name, new { #readonly = "readonly" })
Since you already using a DisplayFor for the same property a hidden input seems more appropriate, so
#Html.HiddenFor(m => m[i].Name)
or if you want to display it twice
#Html.TextBoxFor(m => m[i].Name, new { #readonly = "readonly" })
This applies to the other properties as well

Try using a textbox and hide it to persist the value or use another 'data- property

In case of DropDownListFor, when data is posted back to controller, selected value get lost, so we need to have a hidden textbox to keep the selected value
