Using the post request below the model returns null for both the collections yet it correctly returns the boolean attribute. My expectation was that the collections loaded into the model during the get request would persist to the post request. What am I missing?
EDIT: Essentially I am trying to update the list of invoices based on the users selection of a selectlist and a checkbox.
Controller:
[HttpGet]
[AllowAnonymous]
public async Task<ActionResult> Index(bool displayFalse = true)
{
InvoiceViewModel invoiceView = new InvoiceViewModel();
var companies = new SelectList(await DbContext.Company.ToListAsync(), "CompanyID", "Name").ToList();
var invoices = await DbContext.Invoice.Where(s => s.Paid.Equals(displayFalse)).ToListAsync();
return View(new InvoiceViewModel { Companies = companies,Invoices = invoices, SelectedCompanyID = 0, DisplayPaid = displayFalse});
}
[HttpPost]
[AllowAnonymous]
public async Task<IActionResult> Index(InvoiceViewModel model)
{
model.Invoices = await DbContext.Invoice.Where(s => s.CompanyID.Equals(model.SelectedCompanyID) && s.Paid.Equals(model.DisplayPaid)).ToListAsync();
return View(model);
}
Model:
public class InvoiceViewModel
{
public int SelectedCompanyID { get; set; }
public bool DisplayPaid { get; set; }
public ICollection<SelectListItem> Companies { get; set; }
public ICollection<Invoice> Invoices{ get; set; }
}
View:
#model InvoiceIT.Models.InvoiceViewModel
<form asp-controller="Billing" asp-action="Index" method="post" class="form-horizontal" role="form">
<label for="companyFilter">Filter Company</label>
<select asp-for="SelectedCompanyID" asp-items="Model.Companies" name="companyFilter" class="form-control"></select>
<div class="checkbox">

}

A form only posts back the name/value pairs of its controls (input, textarea, select). Since the only 2 controls you generate are for the SelectedCompanyID and DisplayPaid properties of your model, then only those properties will be bound when post.
From your comments, what your really wanting to do is to update the table of invoices based on the values of the selected company and the checkbox.
From a performance point of view, the approach is to use ajax to update just the table of invoices based on the value of your controls.
Create a new controller method that return a partial view of the table rows
public PartialViewResult Invoices(int CompanyID, bool DisplayPaid)
{
// Get the filtered collection
IEnumerable<Invoice> model = DbContext.Invoice.Where(....
return PartialView("_Invoices", model);
}
Note you may want to make the CompanyID parameter nullable and adjust the query if your wanting to initially display unfiltered results
And a partial view _Invoices.cshtml
#model IEnumerable<yourAssembly.Invoice>
#foreach(var item in Model)
{
<tr>
<td>#Html.DisplayFor(m => item.InvoiceID)</td>
.... other table cells
</tr>
}
In the main view
#model yourAssembly.InvoiceViewModel
#Html.BeginForm()) // form may not be necessary if you don't have validation attributes
{
#Html.DropDownListFor(m => m.SelectedCompanyID, Model.Companies)
#Html.CheckboxFor(m => m.DisplayPaid)
<button id="filter" type="button">Filter results</button>
}
<table>
<thead>
....
</thead>
<tbody id="invoices">
// If you want to initially display some rows
#Html.Action("Invoices", new { CompanyID = someValue, DisplayPaid = someValue })
</tbody>
</table>
<script>
var url = '#Url.Action("Invoices")';
var table = $('#invoices');
$('#filter').click(function() {
var companyID = $('#SelectedCompanyID').val();
var isDisplayPaid = $('#DisplayPaid').is(':checked');
$.get(url, { CompanyID: companyID, DisplayPaid: isDisplayPaid }, function (html) {
table.append(html);
});
});
</script>
The alternative would be to post the form as your are, but rather than returning the view, use
return RedirectToAction("Invoice", new { companyID = model.SelectedCompanyID, DisplayPaid = model.DisplayPaid });
and modify the GET method to accept the additional parameter.
Side note: Your using the TagHelpers to generate
select asp-for="SelectedCompanyID" asp-items="Model.Companies" name="companyFilter" class="form-control"></select>
I'm not familiar enough with them to be certain, but if name="companyFilter" works (and overrides the default name which would be name="SelectedCompanyID"), then you generating a name attribute which does not match your model property and as a result SelectedCompanyID would be 0 (the default for int) in the POST method.
Appending ToList() to the statement that populates companies is converting the SelectList into a List<T>, which the form will not recognize as a SelectList. Also, by using the dynamic var keyword, you are masking this problem. Try this instead:
SelectList companies = new SelectList(await DbContext.Company.ToListAsync(), "CompanyID", "Name");
In general, try to avoid use of var unless the type is truly dynamic (unknown until runtime).
You put your model data out of form, so it would not submited!
<form asp-controller="Billing" asp-action="Index" method="post" class="form-horizontal" role="form">
<label for="companyFilter">Filter Company</label>
<select asp-for="SelectedCompanyID" asp-items="Model.Companies" name="companyFilter" class="form-control"></select>
<div class="checkbox">
<label>
<input type="checkbox" asp-for="DisplayPaid" />Display Paid
<input type="submit" value="Filter" class="btn btn-default" />
</label>
</div>
<br />

#Html.ActionLink("Delete", "Delete", new { id = item.InvoiceID })
</td>
</tr>
}
</table>
</form>
Using a for loop to create the with the companies will make it possible to map back and persist the company values
for(c = 0 ; c < Model.Companies.Count(); c++)
{
<input type='hidden' name='#Html.NameFor(Model.Companies[c].Propery1)' id='#Html.IdFor(Model.Comapnies[c].Propery1)' value='somevalue'>someText />
<input type='hidden' name='#Html.NameFor(Model.Companies[c].Propery2)' id='#Html.IdFor(Model.Comapnies[c].Propery2)' value='somevalue'>someText />
}
this ensures that the list is mapped back as the default model binder expects list to be in ListProperty[index] format

My Index.cshmtl is :
#model IPagedList<Student>
#{
ViewBag.Title = "Index";
}
#Html.Partial("_Student", Model)
My StudentController is
public ActionResult Index(int page=1)
{
var model = dbAllStudents.Students
.OrderByDescending(p => p.LastName)
.ToPagedList(page, 10);
return View(model);
}
The problem happens to "#Html.DisplayNameFor(model => model.LastName)". It is saying that " IPaged does not contatin a definition for LastName.
I have an idea that the problem is caused because to the Index method of Student Controller I need to add .Select but I am not sure for that. I would really appreciate if someone can help me
It's not working, because overloaded method which you want to use doesn't fit with your interface. It's for IEnumerable<> types. You can access to the first element in the list and it should returns you correct value even if list is empty.
Change your table definition to:
<table class="table">
<tr>
<th>
#Html.DisplayNameFor( => Model[0].LastName)
</th>
<th>
#Html.DisplayNameFor(_ => Model[0].FirstName)
</th>
<th>
#Html.DisplayNameFor(_ => Model[0].City)
</th>
<th></th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(_ => item.LastName)
</td>
<td>
#Html.DisplayFor(_ => item.FirstName)
</td>
<td>
#Html.DisplayFor(_ => item.City)
</td>
</tr>
}
</table>
and everything will be ok.
INSERT INTO SaleItem (ProdId, SaleQuantity) SELECT ProdId, BasketProdQuantity FROM Basket;
This is my SQL command and I want to use it with a button on a view. But I don't know how to references method with button on view. And should I use SqlConnection connection = new SqlConnection(connectionString) I already connect my DB with WebConfig and it connected as DefaultConnection.
EDIT:
I'm new at MVC and Web coding so I don't know what to do.
[HttpPost]
public ActionResult Buy(SaleItem saleitem)
{
if (ModelState.IsValid)
{
string query = "INSERT INTO SaleItem (ProdId, SaleQuantity) SELECT ProdId, BasketProdQuantity FROM Basket";
db.Database.ExecuteSqlCommand(query);
db.SaveChanges();
return RedirectToAction("Index", "Basket");
}
return View(saleitem);
}
and there is the view that I want to use buy method.
#model IEnumerable<VeriPark001.Models.Basket>
#{
ViewBag.Title = "Index";
}

<button>I WANT TO CALL ACTION HERE. I search for how to do that and couldn't find a proper way.</button>
<button>#Html.ActionLink("Products", "Index", "Product")</button>
</p>
You can use Html.BeginForm and send a post request to your controller action.
Replace your
<p>
<button>I WANT TO CALL ACTION HERE. I search for how to do that and couldn't find a proper way.</button>
<button>#Html.ActionLink("Products", "Index", "Product")</button>
</p>
with
#using (Html.BeginForm("Buy", "YourController", FormMethod.Post))
{
// Input for your SaleItem model
<button class="btn btn-group btn-group-sm" type="submit">Submit</button>
}
Since your Buy action requires a SaleItem model I'll leave it up to you.
I have implemented a save button in my .NET application on the index page. When I click it, it loads, but does not save anything. I am just using the index page for checkboxes. If I uncheck something and save it, it saves, but also unchecks everything else in that row. Nothing happens when I try to check something. Here is the code I'm using:
Index.cshtml
#using (Html.BeginForm("save", "drnos"))
{
<input type="submit" value="Save" />
}
An example of one of my check box fields:
<td>
#Html.EditorFor(modelItem => item.Soft)
#Html.ValidationMessageFor(modelItem => item.Soft)
</td>
drnosController.cs
[HttpPost]
public ActionResult save(Doctor doc)
{
System.Diagnostics.Debug.WriteLine("Save Called");
db.Entry(doc).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
Here is the whole HTML file:
#model PagedList.IPagedList<drnosv6.Models.Doctor>

Your BeginForm or ActionLink has to point to ActionResult Edit.
When a form is submitted, only the inputs declared within that form get submitted. You only have the submit button in your form, so there are no other fields to fill out your Doctor structure. You need to have your save button on the same form as all your other fields.
I have 3 views (1 Index, 2 Contacts(partialview), 3 Details(partialview))
I have a database with 2 tables tied by ContactId that i can use to get the Details from the database to show. I used ADO to make a model of the database. The 2 tables (classes) are named Contact and ContactTelefon.
Instead of button I tried using #html.ActionLink (as u can see in Contact View) to get the Id from the row, but that takes me to a new page, and it doesn't even show details.
My question is: How could i get the details to show in textboxes so i can edit the data.
All actions must be in same view as far as the user is concerned.
Controller:
ContactsDbEntities db = new ContactsDbEntities();
[HttpGet] //Index
public ActionResult Index()
{
return View();
}
//Contacts
public ViewResult Contacts()
{
var contactsList = db.Contacts.ToList();
return View(contactsList);
}
//Details
public ActionResult Details(int? id)
{
ContactTelefon contactTel = db.ContactTelefons.Find(id);
return View(contactTel);

It seems as if you're starting MVC coming from ASP.NET WebForms. The thing about MVC is that it doesn't do any magic like WebForms so you have to have a good understanding of what happens behind the scenes to be able to make a smooth transition. Also, from the looks of it your database model uses Entity Framework.
First off the way you're handling the Details button is all wrong. What you should be doing is this:
HTML
<input type="button" name="Details" value="Details" class="btn btn-info js-details"
data-id="#item.ContactId" />
JavaScript
$(document).on('click', '.js-details', function (event) {
// get the element that triggered the event
var $element = $(event.currentTarget);
var id = $element.data('id');
// you might have to type in the literal URL if you have a custom route
// here
$.get('#Url.Action("Details","Home")'+ '?id=' + id, function (data) {
$('#divDetails').html(data);
});
});
Let me know if this works for you. There are other things that you can improve but this should be a pretty good start.

Here is my controller code as requested:
var q = (from o in db.Order_Details
where o.ProductID == id
join ord in db.Orders
on o.OrderID equals ord.OrderID
orderby o.Quantity descending
select ord);
var qm = q.Take(3);
return PartialView("_Orders", qm.ToList());
Essentially, you're just trying to pass multiple models to your view. As you can only pass one type to a view, the way to do what you want is to wrap your models in a view model and pass that to your view instead. Something like:
public class ProductViewModel
{
public IPagedList<Product> Products { get; set; }
public IEnumerable<Order> Orders { get; set; }
}
public ActionResult Index()
{
var model = new ProductViewModel();
model.Products = // ... fetch from database
model.Orders = // ... fetch from database
return View(model);
}
The view can now be strongly-typed to the view model:
#model ProductViewModel
