why my checkboxes arent generated? - asp.net-mvc

i have the following controller that calls view with template that generates a set of checkboxes
The controller / Action
public class CompoundsController : Controller
{
//
// GET: /Compounds/
testdbDBContext db = new testdbDBContext();
public ActionResult Index()
{
var comps = db.Compounds.Select(e => new CompoundModel { Id=e.Id, Code=e.Code, Name=e.Name, IsSelected = e.IsSelected }).ToList();
return View(new ChemicalsVM { cModel = comps});
}
}
The view
#model mvca1.Models.ChemicalsVM
#{
ViewBag.Title = "Index";
}
<h2>Index</h2>
#using (Html.BeginForm()) {
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<fieldset>
<legend>ChemicalsVM</legend>
<div class="editor-label">
#Html.LabelFor(model => model.SName)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.SName)
#Html.ValidationMessageFor(model => model.SName)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.DName)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.DName)
#Html.ValidationMessageFor(model => model.DName)
</div>
<div class="editor-label">
#Html.Label("Chemicals")
</div>
<div class="editor-field">
#Html.EditorFor(x=>x.cModel)
#Html.ValidationMessageFor(model => model.cModel)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
#Html.ActionLink("Back to List", "Index")
</div>
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
the template is:
#model mvca1.Models.CompoundModel
#{
ViewBag.Title = "rmplCompoundDB";
}
#Html.HiddenFor(x=>x.Id)
#Html.HiddenFor(x=>x.Code)
#Html.CheckBoxFor(x=>x.IsSelected, (Model.IsSelected)? new {#checked="checked"}:null)
#Html.LabelFor(x=>x.Name)
when i ran the code instead of generating checkboxes with labels it displays the id numbers (that should be hidden)
here is the video of what happens https://youtu.be/1Z2fwfBgyn8
why it does not display the checkboxes as expected?
UPDATE:
here is my ChemicalsVM
public class ChemicalsVM
{
public int Id { get; set; }
public string SName { get; set; }
public string DName { get; set; }
public List<CompoundModel> cModel { get; set; }
public ChemicalsVM()
{
cModel = new List<CompoundModel>();
}
}
here is the CompoundModel class
public class CompoundModel
{
public int Id { get; set; }
public string Code { get; set; }
public string Name { get; set; }
public bool IsSelected { get; set; }
}

The html being rendered means the ViewEngine is not finding the EditorTemplate. The template must be named the same as the class (i.e. CompoundModel.cshtml) and be located in either the /Views/Shared/EditorTemplates or /Views/Compounds/EditorTemplates folders.

why mvc validation does not work in my code?

I have simple MVC code having a form with validation.but my validation for name property(required) does not work.I create BreakPoint in my controller after "InsertStudent" action result.
so I run that and fill the form without filling the name text box and I expect "IsValid" in my controller to be false.but it is true!!!
my view is:
#model HelloWorld.Models.student
#{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>AddStudent2</title>

<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
#Html.ActionLink("Back to List", "Index")
</div>
</body>
</html>
and this is my controller:
public class HomeController : Controller
{
//
// GET: /Home/
public ActionResult index()
{
return View("home");
}
public ActionResult addstudent()
{
student stud = new student();
return View(stud);
}
public ActionResult InsertStudent(student stud)
{
if (ModelState.IsValid==true)
{
//sahih
}
else{
//ghalat
}
return View("addstudent");
}
public ActionResult AddStudent2()
{
student stud2 = new student();
return View(stud2);
}
}
}
and model is:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace HelloWorld.Models
{
public class student
{
public int Id { get; set; }
public string Name { get; set; }
[Required]
public string Family { get; set; }
[Required]
//[MaxLength(5)]
public int Age { get; set; }
public string Email { get; set; }
}
}
please help me
You do not have a Required attribute on your Name property. Add it and it the validation should fail
public class student
{
public int Id { get; set; }
[Required]
public string Name { get; set; }
[Required]
public string Family { get; set; }
[Required]
public int Age { get; set; }
public string Email { get; set; }
}
I was able to solve the problem.
I had to put the [required] attribute below my name property instead of putting it above.
public class student
{
public int Id { get; set; }
[Required(AllowEmptyStrings = false)]
public string Name { get; set; }
[Required(AllowEmptyStrings=false)]
public string Family { get; set; }
[Required(AllowEmptyStrings = false)]
//[MaxLength(5)]
public int Age { get; set; }
public string Email { get; set; }
}

Partial view - Model binding in ASP.NET MVC 4

I have 2 models in my MVC 3 application, CustomerOrder and OrderDetail.
My Model OrderDetail is with List.
Model
public class CustomerOrder
{
public int CustomerId { get; set; }
public int NetPrice { get; set; }
public List<OrderDetail> Orderlist { get; set; }
public CustomerOrder()
{
Orderlist = new List<OrderDetail>();
}
}
public class OrderDetail
{
public string ProductName { get; set; }
public int Quantity { get; set; }
public int Price { get; set; }
public int TotalPrice {get{ return Price*Quantity;} }
}
This is My Controller
public ActionResult CustomerOrder()
{
return View();
}
[HttpPost]
public ActionResult CustomerOrder(CustomerOrder SelectedOrder)
{
DataBase dataBase = new DataBase();
var result = dataBase.InsertData(SelectedOrder);
ViewData["result"] = result;
return View();
}
This is My View for CustomerOrder
#model MvcCustomerOrderClass4g.Models.CustomerOrder
#{
ViewBag.Title = "CustomerOrder";
}
<h2>CustomerOrder</h2>
#using (Html.BeginForm()) {
<fieldset>
<legend>CustomerOrder</legend>
<div class="editor-label">
#Html.LabelFor(model => model.CustomerId)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.CustomerId)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.NetPrice)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.NetPrice)
</div>
<p>
<input type="submit" value="Submit" />
</p>
</fieldset>
}
#{
if (ViewData["result"] != "" && ViewData["result"] != null)
{
<script type="text/javascript" lang="javascript">
alert("Data saved Successfully");
</script>
}
}
My Model OrderDetail is with List. How to use it as a list in my view?
Here I want to add OrderDetail model. I also created another view for OrderDetails, for adding it as Partial in CustomerOrder.
The easiest way would be to create an EditorTemplate:
#model OrderDetail
#Html.HiddenFor(m => m.Id)//your model doesn't seem to have an id?
#Html.DisplayFor(m => m.ProductName)
#Html.EditorFor(m => m.ProductName)
Then in your view with the CustomerOrder model just do this:
#Html.LabelFor(model => model.OrderList)
#Html.EditorFor(model => model.OrderList)

Using one html.editorfor to fill in two model fields

Im trying to use only 1 html.editorfor to fill in two model field in each of my model.
I want the value of this editorfor to be also inserted to my Clientes0013.Client0013
<div class="editor-field">
#Html.EditorFor(model => model.CanaClie0012.Client00130012)
#Html.ValidationMessageFor(model => model.CanaClie0012.Client00130012)
</div>
and this one to be also inserted to Clientes0013.F1Pais00200013
<div class="editor-field">
#Html.EditorFor(model => model.CanaClie0012.F1Pais00200012)
#Html.ValidationMessageFor(model => model.CanaClie0012.F1Pais00200012)
</div>
Kindly show me what should be the right way of doing this.
My Table Model:
public partial class CanaClie0012
{
public string Client00130012 { get; set; }
public string F1Pais00200012 { get; set; }
public string F1Cana02530012 { get; set; }
public string Direcc0012 { get; set; }
public Nullable<System.DateTime> TmStmp0012 { get; set; }
}
public partial class Clientes0013
{
public string Client0013 { get; set; }
public string Nombre0013 { get; set; }
public string F1Pais00200013 { get; set; }
}
My Custom Model to combine the two table is:
public class ClientModel
{
public CanaClie0012 CanaClie0012 { get; set; }
public Clientes0013 Clientes0013 { get; set; }
}
My Controller:
[HttpPost]
public ActionResult ClientCreate(CanaClie0012 canaclie0012, Clientes0013 clientes0013)
{
ClientModel vm = new ClientModel();
if (ModelState.IsValid)
{
db.CanaClie0012.Add(canaclie0012);
db.Clientes0013.Add(clientes0013);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(vm);
}
My View:
#model MvcApplication1.Models.ClientModel
#{
ViewBag.Title = "ClientCreate";
}
<h2>ClientCreate</h2>
<script src="#Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

</div>
<div class="editor-label">

</div>
<div class="editor-label">
Contact Number
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Clientes0013.Nombre0013)
#Html.ValidationMessageFor(model => model.Clientes0013.Nombre0013)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
#Html.ActionLink("Back to List", "Index")
</div>
Got it.. modified my controller action to this one.
[HttpPost]
public ActionResult ClientCreate(CanaClie0012 canaclie0012, Clientes0013 clientes0013)
{
ClientModel vm = new ClientModel();
if (ModelState.IsValid)
{
clientes0013.Client0013 = canaclie0012.Client00130012;
clientes0013.F1Pais00200013 = canaclie0012.F1Pais00200012;
db.CanaClie0012.Add(canaclie0012);
db.Clientes0013.Add(clientes0013);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(vm);
}

Multi Table in a view

I'm trying to make a strongly typed "Create View" so I could insert data into two tables simultaneously. However, when I create the view, the fields from my table are not included in my model. Can you tell what is the right way of doing this?
My Table Model:
public partial class CanaClie0012
{
public string Client00130012 { get; set; }
public string F1Pais00200012 { get; set; }
public string F1Cana02530012 { get; set; }
public string Direcc0012 { get; set; }
public Nullable<System.DateTime> TmStmp0012 { get; set; }
}
public partial class Clientes0013
{
public string Client0013 { get; set; }
public string Nombre0013 { get; set; }
public string F1Pais00200013 { get; set; }
}
My Custom Model to combine the two table is:
public class ClientModel
{
public IQueryable<CanaClie0012> CanaClie0012 { get; set; }
public IQueryable<Clientes0013> Clientes0013 { get; set; }
}
My Controller: (Not really sure if im this correctly)
[HttpPost]
public ActionResult ClientCreate(CanaClie0012 canaclie0012, Clientes0013 clientes0013)
{
ClientModel vm = new ClientModel();
if (ModelState.IsValid)
{
db.CanaClie0012.Add(canaclie0012);
db.SaveChanges();
db.Clientes0013.Add(clientes0013);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(vm);
}
My view:
#model MvcApplication1.Models.ClientModel
#{
ViewBag.Title = "ClientCreate";
}
<h2>ClientCreate</h2>
<script src="#Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
#using (Html.BeginForm()) {
#Html.ValidationSummary(true)
<fieldset>
<legend>ClientModel</legend>
<div class="editor-label">
Client Name
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Client00130012)
#Html.ValidationMessageFor(model => model.Client00130012)
</div>
<div class="editor-label">
Pais
</div>
<div class="editor-field">
#Html.EditorFor(model => model.F1Pais00200012)
#Html.ValidationMessageFor(model => model.F1Pais00200012)
</div>
<div class="editor-label">
Address
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Direcc0012)
#Html.ValidationMessageFor(model => model.Direcc0012)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Nombre0013)
#Html.ValidationMessageFor(model => model.Nombre0013)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
#Html.ActionLink("Back to List", "Index")
</div>
One big problem is that your view is strongly-typed to your ClientModel class. This class does not include the members that you are referencing in your view. Instead, that class includes lists of objects that include those members. At this point, your view probably doesn't even compile.
Try changing your ClientModel class as follows:
public class ClientModel
{
public CanaClie0012 CanaClie0012 { get; set; }
public Clientes0013 Clientes0013 { get; set; }
}
then your view would reference the members such as:
<div class="editor-label">
Client Name
</div>
<div class="editor-field">
#Html.EditorFor(model => model.CanaClie0012.Client00130012)
#Html.ValidationMessageFor(model => model.CanaClie0012.Client00130012)
</div>
similarly for members of your Clientes0013 members.
One additional thing: you don't need to call db.SaveChanges(); twice in your controller. Instead, insert into both tables and do a single save:
db.CanaClie0012.Add(canaclie0012);
db.Clientes0013.Add(clientes0013);
db.SaveChanges();

ASP.NET MVC 3 Binding to a Collection inside an Object

I have a model with an object that contains a collection like this:
namespace API.Example.Models
{
public class OrderTest
{
public string UserName { get; set; }
public string Token { get; set; }
public POCO.Order Order { get; set; }
}
}
namespace Supertext.API.POCO
{
public class Order
{
public List<TranslationGroup> Groups = new List<TranslationGroup>();
}
public class TranslationGroup
{
public string GroupId { get; set; }
}
}
The Order object contains a collection called Groups.
In the view I display the collection like this (with the index like explained in several examples)
#Html.LabelFor(m => m.UserName)
#Html.TextBoxFor(m => m.UserName)
#for (int i = 0; i < Model.Order.Groups.Count; i++)
{
#Html.LabelFor(m => Model.Order.Groups[i].GroupId)
#Html.TextBoxFor(m => Model.Order.Groups[i].GroupId)
}
And this is the Controller method that gets called:
[HttpPost]
public ActionResult Index(Models.OrderTest model)
The HTML of the UserName element:
<input id="UserName" name="UserName" style="width:300px;" type="text" value="">
and the GroupId element:
<input id="Order_Groups_0__GroupId" name="Order.Groups[0].GroupId" type="text" value="1">
I can access the UserName, but there is nothing in the collection.
What am I missing?
And whats the difference between using m.UserName and Model.Order.Groups (I mean m and Model). Is that my issue?
Each property of POCO entity use like a property managed by the CLR. Let the CLR manage the create of instance and etc.. or you can generate conflicts that can throw issues like you have.
Change your Order code to this:
public class Order
{
public List<TranslationGroup> Groups { get; set; }
}
--EDIT
I create a new project and add the following class:
public class TranslationGroup
{
public string GroupId { get; set; }
}
public class Order
{
public List<TranslationGroup> Groups { get; set; }
}
public class OrderTest
{
public string UserName { get; set; }
public string Token { get; set; }
public Order Order { get; set; }
}
Here my code behind of the OrderTestController:
public ActionResult Index()
{
var orderTest = new Models.OrderTest()
{
UserName = "Vinicius",
Token = "12as1da58sd558",
Order = new Models.Order()
{
Groups = new List<Models.TranslationGroup>()
{
new Models.TranslationGroup() { GroupId = "a54s"},
new Models.TranslationGroup() { GroupId = "a87d"},
new Models.TranslationGroup() { GroupId = "2gf4"}
}
}
};
return View(orderTest);
}
[HttpPost]
public ActionResult Index(Models.OrderTest model)
{
return View();
}
And Index View:
#model TestCollection.Models.OrderTest
#{
ViewBag.Title = "Index";
}
<h2>
Index</h2>
<script src="#Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
#using (Html.BeginForm())
{
#Html.ValidationSummary(true)
<fieldset>
<legend>OrderTest</legend>
<div class="editor-label">
#Html.LabelFor(model => model.UserName)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.UserName)
#Html.ValidationMessageFor(model => model.UserName)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.Token)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Token)
#Html.ValidationMessageFor(model => model.Token)
</div>
#for (int i = 0; i < Model.Order.Groups.Count; i++)
{
<div class="editor-label">
#Html.LabelFor(m => Model.Order.Groups[i].GroupId)
</div>
<div class="editor-field">
#Html.TextBoxFor(m => Model.Order.Groups[i].GroupId)
</div>
}
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
#Html.ActionLink("Back to List", "Index")
</div>
So, if you run, and go to OrderTest view, you 'll see all attributes filled, and when you click in create, all things will be binded (the collection as well).
