Returning array or List of models from form in Razor View to action on Submit

I am working on a learning project in which I created a view which displays a list of Delisted Books( isActive = false) populated by calling an api.
The view has a list of books + a checkbox in front of each book so that upon clicking the books we want to set active and hit the save button, it returns the books which are selected to the action in controller.
This is the view I am working with :
#model IEnumerable<MvcBooksList.Models.Book>
#{
ViewData["Title"] = "Delisted Books";
}
#if (Model != null)
{
#using (Html.BeginForm("DelistedForm", "Book", FormMethod.Post, new { #id = "myForm" }))
{
<table class="table">
<thead>
<tr>
<th>
#Html.DisplayNameFor(model => model.BookName)
</th>
<th>
#Html.DisplayNameFor(model => model.Author)
</th>
<th>
#Html.DisplayNameFor(model => model.Publisher)
</th>
<th>
Enlist
</th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.BookName)
#Html.HiddenFor(modelItem => item.BookName)
</td>
<td>
#Html.DisplayFor(modelItem => item.Author)
#Html.HiddenFor(modelItem => item.Author)
</td>
<td>
#Html.DisplayFor(modelItem => item.Publisher)
#Html.HiddenFor(modelItem => item.Publisher)
</td>
<td>
#Html.CheckBoxFor(modelItem => item.IsActive)
</td>
</tr>
}
</tbody>
</table>
<input type="submit" value="Save" /> <input type = "button" value = "Cancel" onclick = "location.href='#Url.Action("Index", "Home")'" />
}
}
else
{
<h3>No Books currently delisted</h3>
}
This is the model:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
namespace MvcBooksList.Models
{
public class Book
{
public string BookName { get; set; }
public string Author { get; set; }
public string Category { get; set; }
public string Subcategory { get; set; }
public string Publisher { get; set; }
public bool IsActive { get; set; }
public double? Price { get; set; }
public int Pages { get; set; }
public string AddedBy { get; set; }
public string ModifiedBy { get; set; }
public DateTime AddedOn { get; set; }
public DateTime LastModifiedOn { get; set; }
}
}
and this is the controller:
[HttpPost]
public async Task<ActionResult> DelistedForm(IEnumerable<Book> fromDelist)
{
foreach (var item in fromDelist)
{
if (item.IsActive == true)
//CALL
{
using (HttpClient client = new HttpClient())
{
client.BaseAddress = baseAddressOfBookApi;
var resopnse = await client.GetAsync("Book/EnlistBook?id="+item.BookName.ToString());
if (!resopnse.IsSuccessStatusCode)
{
return View(null);
}
}
}
}
return RedirectToAction("Index","Home");
}
Dont mind the code inside the action.
So when I press the submit button nothing gets passed to the action. The fromDelist collection is showing a count of 0.
So ,what am I doing wrong.
And Is it possible that I can return the names of books that are checked.

}
}
return View(bookdetails);
}

}

}

Try to replace foreach by for
#model List<MvcBooksList.Models.Book>
#for (int i = 0; i < Model.Count(); i+=1)
{
......
<td>
#Html.DisplayFor(model=> model[i].Publisher)
#Html.HiddenFor(model => model[i].Publisher)
</td>
<td>
#Html.CheckBoxFor(model => model[i].IsActive)
</td>
</tr>
.... and so on for all
and replace a table header
<th>
#Html.DisplayNameFor(model => model[0].BookName)
</th>
<th>
#Html.DisplayNameFor(model => model[0].Author)
</th>

Parent-Child model (multiple model) in one view (ASP.NET Core (C#) + MVC + Entity Framework)

I am trying to make a Web App which has Parent-Child model (multiple model) in one view (ASP.NET Core + MVC + Entity Framework).
The following is input (input No.1).
This is "Views/Blogs/index.cshtml"
The following is also input (input No.2).
This is "Views/Tags/index.cshtml"
The following is my expecting output (output No.1).
I have written the following "Views/Blogs/cshtml".
#model IEnumerable<urlapp12.Models.UrlTag>
#{
ViewData["Title"] = "Index";
}
<h2>Index</h2>
<p>
<a asp-action="Create">Create New</a>
</p>
<table class="table">
<thead>
<tr>
<th>
#Html.DisplayNameFor(model => model.Blog.Userid)
</th>
<th>
#Html.DisplayNameFor(model => model.Blog.Url)
</th>
<th>
#Html.DisplayNameFor(model => model.Blog.LastUpdatedAt_UtcDt)
</th>
<th>
#Html.DisplayNameFor(model => model.Blog.LastUpdatedAt_LocalDt)
</th>
<th></th>
<th></th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.Blog.Userid)
</td>
<td>
#Html.DisplayFor(modelItem => item.Blog.Title)
</td>
<td>
#Html.DisplayFor(modelItem => item.Blog.LastUpdatedAt_UtcDt)
</td>
<td>
#Html.DisplayFor(modelItem => item.Blog.LastUpdatedAt_LocalDt)
</td>
<td>
#foreach (var childItem in item.Tag)
{
#Html.DisplayFor(modelItem => childItem.tagItem)
}
</td>
<td>
<a asp-action="Edit" asp-route-id="#item.Blog.BlogId">Edit</a> |

And executed, I have gotten the following error.
(output No.2. The real unexpected output)

junkangli and Gimly, thank you for reply.
I have tried the Gimly's idea.
public async Task<IActionResult> Index()
{
return View(await _context.Blog.Include(b => b.Tags).ToListAsync());
}
Then Visual Studio told me that "'Blog' does not include 'Tags' definition" error.
So I have changed Tags to Tag, My Visual Studio says it is O.K.
public async Task<IActionResult> Index()
{
return View(await _context.Blog.Include(b => b.Tag).ToListAsync());
}
I run my codes for Debug mode, the web application returned the following error.
An unhandled exception occurred while processing the request.
InvalidOperationException: The model item passed into the ViewDataDictionary is of type 'System.Collections.Generic.List1[urlapp12.Models.Blog]', but this ViewDataDictionary instance requires a model item of type 'System.Collections.Generic.IEnumerable1[urlapp12.Models.UrlTag]'.

First, about the exception you're getting, the error message is pretty explicit, and #junkangli explained it will in its comment, you're not returning the correct object to the View. View expects an IEnumerable<UrlTag> and you're sending it an IEnumerable<Blog>.
Now, about the core of your issue, you'll want to load the list of tags in your query for getting the list of Blogs, so, in your controller's Index action, you should do something like:
public async Task<IActionResult> Index()
{
return View(await _context.Blog.Include(b => b.Tags).ToListAsync());
}
Then, in your view, you should be able to access your tags and create a while loop to display all your tags.

Invalid object name 'dbo.TableName' ASP

I looked everywhere and I can't figure out what the problem is with my asp project.
Basically I get this error
Invalid object name dbo.Enquires.
It's looking for a table which doesn't exist, and I never mention that table anywhere, not sure why it's looking for it.

For some reason I keep getting the error and I can't seem to fix it. I don't have much experience with asp.net. Here is the error I get http://pastebin.com/Gmmhn0VX
It keeps looking for dbo.Enquires and that doesn't exist, I also searched the whole project and I can't see anywhere that something refers to dbo.Enquires.
Any help would be appreciated.
Edit: Here is the ApplicationDBContext
using System.Data.Entity;
using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
namespace PetePersonalTrainerFinal.Models
{
// You can add profile data for the user by adding more properties to your ApplicationUser class, please visit http://go.microsoft.com/fwlink/? LinkID=317594 to learn more.
public class ApplicationUser : IdentityUser
{
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
return userIdentity;
}
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
public System.Data.Entity.DbSet<PetePersonalTrainerFinal.Models.Price> Prices { get; set; }
public System.Data.Entity.DbSet<PetePersonalTrainerFinal.Models.Enquire> Enquiries { get; set; }
}
}

Decorating Enquire Model class with [Table("Enquiries")] fixed the issue.

Variables from one table display along side another in the view

Hi there I was looking for a way to select certain fields from the different database tables and output it into one table in the view.This is the code I have so far although it is only able to retrieve information from the patients table. Any help would be greatly appreciated thanks.
model
namespace ChampPMS.Models
{
public class Patient
{
public int PatientID { get; set; }
public string HouseChartNo { get; set; }
public string ClinicChartNo { get; set; }
public string Title { get; set; }
public string FirstName { get; set; }
public DateTime DOB { get; set; }
Dont think this is right.
//Other Table variables
public Admission ExpectedDate { get; set; } ------->from bed
public Beds Bed { get; set; } ------->from admissions
}
public class Beds
{
public int BedID { get; set; }
public int RoomID { get; set; }
public string Bed { get; set; }
}
public class Admission
{
public int AdmissionID { get; set; }
public int PatientID { get; set; }
public DateTime ExpectedDate { get; set; }
public int BedID { get; set; }
public string Phone { get; set; }
}
public PatientDBContext()

}
public DbSet<Admission> Admission { get; set; }
public DbSet<Beds> Beds { get; set; }
public DbSet<Patient> Patient { get; set; }

Rather than return the data directly from the database to the View you should create a View-Model in the controller action.
This ViewModel would contain all of the information that you need to display.
Using a ViewModel ensures that only the data required for the View is returned. It means rendering your View is more simple and you can use data from many different sources in one single ViewModel.

Paging In MVC Table Grid

What I am trying to achieve is to include paging functionality in a grid (generated with an html table and a foreach statement).
I am not allowed to use entity framework, webgrid, or any other third party grid.
Below are the details of my task:
DemoTestData.cs file
namespace Demo.Data
{
public class DemoTestData
{
DemoTestModel objdemoTestModel = null;
public string connectionString { get; set; }
public SqlConnection objConnection { get; set; }
public SqlCommand objCommand { get; set; }
public SqlDataReader objReader { get; set; }
public List<DemoTestModel> GetAllDemoTest()
{
List<DemoTestModel> listDemoTest = new List<DemoTestModel>();
try
{
objConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);
objConnection.Open();
objCommand = new SqlCommand("sp_DemoTest", objConnection);
objCommand.CommandType = System.Data.CommandType.StoredProcedure;
objReader = objCommand.ExecuteReader();
if (objReader.HasRows)
{
while (objReader.Read())
{
// list will be populated here.
objdemoTestModel = new DemoTestModel();
objdemoTestModel.Id = Convert.ToInt32(objReader["Id"].ToString());
objdemoTestModel.Column1 = objReader["Column1"].ToString();
objdemoTestModel.Column2 = objReader["Column2"].ToString();
objdemoTestModel.Column3 = objReader["Column3"].ToString();
objdemoTestModel.Column4 = objReader["Column4"].ToString();
objdemoTestModel.Column5 = objReader["Column5"].ToString();
objdemoTestModel.Column6 = objReader["Column6"].ToString();
listDemoTest.Add(objdemoTestModel);
}
//return listStateModel;
}
}
catch (Exception ex)
{
string m = ex.Message;
}
finally
{
if (objConnection != null)
{
objConnection.Close();
}
}
return listDemoTest;
}
}

(if..else condition is used to generate dynamic controls)
This is the rendered view
It would be very nice if anyone could provide a solution.
