I'm trying to create a drop down list so I can filter the the index results but I keep getting an error
"Compiler Error Message: CS1061: 'IEnumerable' does not
contain a definition for 'DayOfWeek' and no extension method
'DayOfWeek' accepting a first argument of type
'IEnumerable' could be found (are you missing a using
directive or an assembly reference?)"
The line that errors out is
Html.DropDownListFor(model => model.DayOfWeek, htmlAttributes: new { #class = "form-control" })".
Do I need to do something in the model or do I have syntax errors?
You misunderstood what first parameter is for. It is to point where selected item should go for. It is for selectedItem variable. Check this blog post: https://odetocode.com/blogs/scott/archive/2013/03/11/dropdownlistfor-with-asp-net-mvc.aspx. You have to create separate class for model with list of elements and variable SelectedDayOfWeek.
Model class:
public class CheckDaysViewModel
{
public IEnumerable<CheckDays> CheckDays {get;set;}
public IEnumerable<SelectListItem> CheckDaysAsSelectedList => this.CheckDays.Select(e => new SelectListItem(e.DayOfWeek, e.DayOfWeek));
public CheckDays SelectedDay {get;set;}
}

Try to replace
#Html.DisplayFor(model => Model.ImagePath)
with
<img src= "#Url.Content(item.ImagePath)" alt="Image" />
Should work.
Your define that your model is a collection:
#model IEnumerable<BOL.tbl_Advertisement>
So every time you write Model., you are referencing this collection.
The collection (IEnumerable<BOL.tbl_Advertisement>) has no property for Imagepath, as the error message tells you.
IEnumerable<tbl_Advertisement> does not contain a definition for Imagepath
Rather, the elements (tbl_Advertisement) of the collection have this property.
This is what Stephen and Igor meant when they wrote that you need to access the Imagepath through the elements of the collection.
Either by looping over the collection:
#foreach (var item in Model) {
<img src= "#Url.Content(item.ImagePath)" alt="Image" />
}
Or for the first element only:
var imagePath = Model.ElementAt(0).ImagePath;
I have this partial View as below:
#model IPagedList<Student>

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.
I keep getting an error message along the lines of:
..but this dictionary requires a model item of type..
My view I'm trying to put the partial view into is:

Your partial view is expecting this model (you are declaring it at the top of you partial view)
#model IEnumerable<TheNovelMachine.Models.Novel>
You should pass that model in this line:
#{
Html.RenderPartial("~/Views/Shared/_NovelProfile.cshtml", Model.Novels);
}
That should work, assuming Model.Novels is of this type IEnumerable<TheNovelMachine.Models.Novel> or it can be converted to that type.
Here you have an example with more details, but the idea is the same. If you don't pass this as a parameter, then the partial view can't be constructed (that's why you are getting that error).
MSDN Documentation here for RenderPartial method.
So even though there are other answers as to what you need to do, here is what is actually happening, so you know in the future.
#Html.RenderPartial("_NovelProfile");
would be the same code as:
#Html.RenderPartial("_NovelProfile", Model)
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:

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>

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

How do I get to _SelectedCountries from my model then?
Also, I use an IEnumerable model to populate a table beneath the list box. This list box is outside of the table and has no reason to be inside of it.
EDIT - POSTED entire view.
I am trying to treat the model within the view as a single object,

Your assumption is correct.
How do I get to _SelectedCountries from my model then?
You need a new model and add IEnumerable inside it.
public class SomeViewModel
{
public IEnumerable<vw_SpecialQuestionDefinition>
SpecialQuestionDefinitions { get; set; }
public string[] _SelectedCountries { get; set; }
}
Then foreach will finally like this -
#foreach (var item in Model.SpecialQuestionDefinitions)
