How would one go about to pass a hardcoded List of Cards (a deck) from View to Controller. I've tried several different things to pass it, but with various results. My index is a screen with 52 cards where you can draw the top card, and I want to be able to shuffle them, and even add a new deck to the current deck, and update the hardcoded list.
This is some of the relevant code. Any suggestions?
EDIT: The formpost method is where I am not sure about. I could probably add just a new List of Cards in the Action, but then the issue will arise again when I try to add a new deck to the current deck.
public class Card
{
public Suit Suit { get; set; }
public Cardnumber Cardnumber { get; set; }
public Card(Cardnumber c, Suit s)
{
this.Cardnumber = c;
this.Suit = s;
}
}
DeckOfCardsViewModel.cs
public class DeckOfCardsViewModel
{
public int ID { get; set; }
public List<Card> Cards { get; set; }
}
HomeController.cs
public ActionResult Index()
{
if (deck.Count < 1)
{
deck = new Deck().NewDeck();
deckViewModel = new DeckOfCardsViewModel();
deckViewModel.ID = 1;
deckViewModel.Cards = deck;
return View(deckViewModel);
}
else return View();
}
public ActionResult ShuffleDeck(DeckOfCardsViewModel shuffledDeck)
{
shuffledDeck.Cards = shuffledDeck.Cards.OrderBy(a => Guid.NewGuid()).ToList();
deckViewModel = shuffledDeck;
return View("Index",shuffledDeck);
}
Index.cshtml
#model DeckOfCards.Models.DeckOfCardsViewModel
#using (Html.BeginForm("ShuffleDeck", "Home", ****FormMethod.Post?***))
{
#Html.HiddenFor(Model => Model.Cards);
#Html.HiddenFor(Model => Model.ID);
<button class="btn btn-primary" name="TEST" type="submit" value="Submit">Shuffle</button>
}

I am trying to implement a search panel with several checkbox to filter a table data, but i have a problem. I cant retain value of input checked after submit.
How can I solve?
My model :
public class OrdineView
{
public int anno { get; set; }
public Int32 nrOrdine { get; set; }
public string centro { get; set; }
[DataType(DataType.Date), DisplayFormat(DataFormatString = "{0:d}")]
public DateTime? data { get; set; }
public String codice { get; set; }
public String ragsoc { get; set; }
[DisplayFormat(DataFormatString = "{0:C}")]
public Nullable<double> importo;
}
I have a Search model:
public class OrdiniSearchModel
{
public int? anno {get;set;}
public String[] Distinzione {get;set;}
}
public class OrdiniBusinessLogic
{
private NORTHWNDEntities1 db;
public OrdiniBusinessLogic()
{
db = new NORTHWNDEntities1();
}
public IQueryable<OrdineView> GetOrdini(OrdiniSearchModel ordiniSearch)
{
var queryOrdineView = (from ordine in db.ORDINI
join cliente in db.CLIENTI on ordine.Codcli equals cliente.Codana
select new OrdineView
{
anno = ordine.Anno,
nrOrdine = ordine.Numord,
centro = ordine.Codcen,
data = ordine.Datord,
codice = ordine.Codcli,
ragsoc = cliente.Ragso1,
importo = ordine.Totord
}).ToList().AsQueryable();
var model = queryOrdineView;
if (ordiniSearch.anno != null)
{
model = model.Where(o => o.anno == ordiniSearch.anno);
}
if (ordiniSearch.Distinzione != null && ordiniSearch.distinzione.Count() > 0)
{
List<string> distinzioniSelezionate = new List<string>();
foreach (var item in ordiniSearch.Distinzione)
{
distinzioniSelezionate.Add(item);
}
model = model.Where(o => distinzioniSelezionate.Contains(o.distinzione));
}
return model;
}
}
My Controller:
public ActionResult Index(OrdiniSearchModel searchModel, int? pageNumber )
{
ViewBag.Anno = db.ORDINI.Select(o => new { o.Anno }).Distinct().OrderByDescending(o => o.Anno).Select(o => o.Anno);
var searchLogic = new OrdiniBusinessLogic();
var model = searchLogic.GetOrdini(searchModel);
return View(model.OrderBy(i => i.codice).ToPagedList(pageNumber ?? 1, 10));
}
In my view I have
<input name="Distinzione" type="checkbox" value="001">001
<input name="Distinzione" type="checkbox" value="002">002
...and so on
After submit I get data correctly but lose checked state.
UPDATE: Based on the comments, I updated the view and adde more code.
If you mean that the checkboxes don't stay checked after the page is refreshed. It's because you don't tell them which should be checked. There is one possible solution for you. Create a simple helper method right in the view where you need the checkboxes. This method just checks the array of values and if it finds the value there, it will render a checkbox with checked state.
View.cshtml
#model OrdinePagedList
#MyCheckbox("001")
#MyCheckbox("002")
#helper MyCheckbox(string value)
{
if (Model.Distinzione.Contains(value))
{
<input type="checkbox" name="Distinzione" value="#value" checked="checked"/>
}
else
{
<input type="checkbox" name="Distinzione" value="#value" />
}
#value
}
I suggest to create a new view model class:
public class OrdinePagedList
{
public IEnumerable<OrdiniView> Pages { get; set; }
public IEnumerable<string> Distinzione { get; set;
}
And update either your business logic so that it returns this new class
// from
public IQueryable<OrdineView> GetOrdini(OrdiniSearchModel ordiniSearch)
// to
public OrdinePagedList GetOrdini(OrdiniSearchModel ordiniSearch)
or update the controller:
public ActionResult Index(OrdiniSearchModel searchModel, int? pageNumber )
{
ViewBag.Anno = db.ORDINI.Select(o => new { o.Anno }).Distinct().OrderByDescending(o => o.Anno).Select(o => o.Anno);
var searchLogic = new OrdiniBusinessLogic();
var pages = searchLogic.GetOrdini(searchModel);
OrdinePagedList model = new OrdiniPagedList {
Pages = pages.OrderBy(i => i.codice).ToPagedList(pageNumber ?? 1, 10),
Distinzione = searchModel.Distinzione
}
return View(model);
}
or if you don't want (or can't) create the new view model (but I strongly recommend to do so). You can use ViewBag to pass the additinal collection of checked values:
public ActionResult Index(OrdiniSearchModel searchModel, int? pageNumber)
{
ViewBag.Distinzione = searchModel.Distinzione;
// original code
}
and then you'll just have to update the helper method. For the sake of simplicity I don't check if the ViewBag.Distinzione exists. But you should.
#helper MyCheckbox(string value)
{
if (ViewBag.Distinzione.Contains(value))
{
<input type="checkbox" name="Distinzione" value="#value" checked="checked"/>
}
else
{
<input type="checkbox" name="Distinzione" value="#value" />
}
#value
}
In short. You need to make sure that the data (collection of checked values), you get in controller, are being sent back to the view.
List<string> distinzioniSelezionate = new List<string>();
if (searchModel.distinzione != null && searchModel.distinzione.Count() > 0)
{
foreach (var item in searchModel.distinzione)
{
distinzioniSelezionate.Add(item);
}
}
OrdinePagedList model = new OrdinePagedList
{
Pages = pages.OrderBy(i => i.Codice).ToPagedList(pageNumber ?? 1, 10),
Distinzione = distinzioniSelezionate
};
I had to modify the ActionResult because Distinzione is not empty
I am in need of how the correct way to do this.
I can not use forms authentication
A user will "login" or confirm identity based on a value
I need to walk the user through a series of pages like so
Contact/MailAddress
Contact/Phone
Contact/Email
Contact/Summary
Questionaire/Question1
Questionaire/Question2
Questionaire/Question3
Questionaire/Summary
Final/Certify
Final/Review
I plan on using Session to hold the data but I'm having trouble figuring out how to pass the values to other views and how Redirect to other pages.
Any help will do...
Lets say you have some models like this
public class ContactModel
{
public string MailAddress { get; set; }
public string Phone { get; set; }
public string Email { get; set; }
}
public class QuestionaireModel
{
public string Question1Answer { get; set; }
public string Question2Answer { get; set; }
public string Question3Answer { get; set; }
}
public class ContactQuestionaireModel
{
public ContactModel Contact { get; set; }
public QuestionaireModel Question { get; set; }
}
and you want to persist this model from view to view and action to action. In you controller you can create 2 actions. one for your first view and one for your second
Controller
public ActionResult ContactAddress()
{
var model = new ContactQuestionaireModel();
return View(model);
}
[HttpPost]
public ActionResult ContactAddress(ContactQuestionaireModel model)
{
var currentModel = TempData["currentModel"] as ContactQuestionaireModel;
currentModel.Contact.MailAddress = model.Contact.MailAddress;
TempData["currentModel"] = currentModel;
return RedirectToAction("ContactPhone");
}
public ActionResult ContactPhone()
{
var model = TempData["currentModel"] as ContactQuestionaireModel;
return View(model);
}
[HttpPost]
public ActionResult ContactPhone(ContactQuestionaireModel model)
{
var currentModel = TempData["currentModel"] as ContactQuestionaireModel;
currentModel.Contact.Phone = model.Contact.Phone;
TempData["currentModel"] = currentModel;
return RedirectToAction("ContactEmail");
}
in the first action ContactAddress you create a new blank model and pass that in to your view ContactAddress. In that view you can set TempData["currentModel"] equal to the model you are passing in. This will stay in TempData for 1 post back to the server. You dont need to do this on the first page since it's blank anyway but i'm doing it to save time.
View ContactAddress
#model WebApplication3.Models.ContactQuestionaireModel
#{
ViewBag.Title = "Contact Address";
TempData["currentModel"] = Model; //this will be available to me in the HttpPost action
}
#using (Html.BeginForm())
{
<div class="form-group">
#Html.LabelFor(m => m.Contact.MailAddress, new { #class = "col-md-2 control-label" })
<div class="col-md-10">
#Html.TextBoxFor(m => m.Contact.MailAddress, new { #class = "form-control" })
</div>
</div>
<button type="submit">Submit</button>
}
you'll notice in the controller code that the Post Action for ContactAddress is setting a var currentModel equal to what is in TempData["currentModel"] which was set in the ContactAddress view. Before you do a redirect to the next action ContactPhone set TempData["currentModel"] back to the model you are building and use it in the next action.
You do have the option of adding the Model as a parameter to each action and passing the currentModel object like
public ActionResult ContactPhone(ContactQuestionaireModel model)
return RedirectToAction("ContactPhone", currentModel);
its up to you really. this is not a foolproof way. page refreshes and back and forward buttons could clear out everything that was entered. Storing the information in Session or actually saving the data in a database might be more optimal.
I advise against doing what you are attempting to do by logging in with session but what you are looking for is:
TempData.yourModel = new SomeModel { Data = "yourData" };
//next page
var model = (SomeModel)TempData.yourModel;
and
RedirectToAction("yourController", "yourAction");
I'm trying to post data from a bunch of text fields using the following:
Controller:
[HttpGet]
public ActionResult Order()
{
OrderViewModel vm = new OrderViewModel();
vm.Id = "some id";
List<IOrderItem> itemList= new List<IOrderItem>();
for (int i = 0; i <= 10; i++)
{
OrderItem x = new OrderItem();
x.ItemId = i + "";
itemList.Add(x);
}
vm.OrderItemList = itemList;
return View(vm);
}
[HttpPost]
public IActionResult Order(OrderViewModel model)
{
return View("blabla");
}
These are the models:
public class OrderViewModel : B.IOrderItemViewModel
{
private List<IOrderItem> orderItems;
public List<IOrderItem> OrderItemList
{
get { return orderItems; }
set { orderItems = value; }
}
private string orderId;
public string Id
{
get { return orderId; }
set { orderId = value; }
}
}
public class OrderItem : IOrderItem
{
private string orderItemId;
public string ItemId
{
get { return orderItemId; }
set { orderItemId = value; }
}
private string _description;
public string Description
{
get { return _description; }
set { _description = value; }
}
}
this is the view:
#model OrderViewModel
#using (Html.BeginForm("Order", "Home", FormMethod.Post))
{
#for (int i = 0; i < Model.OrderItemList.Count; i++)
{
#Html.HiddenFor(x => x.OrderItemList[i].ItemId)
#Html.TextBoxFor(x => x.OrderItemList[i].Description)
<br />
}
<input type="submit" value="submit" />
}
Here is the problem - The interfaces are in another project, let's call it B. I reference B in the project.json file for the main project, A. In B, I just defined the two interfaces the are inherited above.
If I do not use any interfaces, and I just use the objects
e.g. instead of :
List<IOrderItem> OrderItemList
I use :
List<OrderItem> OrderItemList
When I run the project, and hit the view, I see the textboxes. I fill in some data and hit submit. It goes to the controller as expected. If I put a breakpoint in the HttpPost actionresult method, and look at the model, I can see all the data I entered. Perfect.
If I use the code above, where I am inheriting from some interfaces, it does not work. The view loads, I enter in some data, I post, it hits the breakpoint, but the model is empty and it's all null.
Any ideas / help would be greatly appreciated!
You cant bind to interfaces. The process of model binding involves first initializing your model (internally the DefaultModelBinder uses Activator.CreateInstance()) , but you can't initialize an interface (how would it know which type to initialize), which is why
public List<OrderItem> OrderItemList { get; set; }
works, but
public List<IOrderItem> OrderItemList { get; set; }
wont.
This article discusses it more detail and includes a section on creating a custom Abstract Model Binder that may solve your problem.
I would like to click on button and use Next method in Controller, but i dont want go to another view! I want stay here in VIEW and my property should be change. This idea doesnt work :(( How can i do it??
Its my controller
public class VisitsController : Controller
{
Terminarz terminarz = new Terminarz();
Daty data = new Daty();
public VisitsController()
{
terminarz.aktualnaData = DateTime.Now.Date;
terminarz.pierwszyDzienTyg = data.pierwszyDzienTygodnia(terminarz.aktualnaData);
terminarz.ostatniDzienTyg = data.ostatniDzienTygodnia(terminarz.aktualnaData);
}
[ActionName("index")]
public ActionResult Index()
{
ViewBag.data = terminarz.aktualnaData;
ViewBag.pierwszyDzien = terminarz.pierwszyDzienTyg.ToString("dd/MM/yyyy ");
ViewBag.ostatniDzien = terminarz.ostatniDzienTyg.ToString("dd/MM/yyyy ");
ViewBag.wtf = terminarz.pierwszyDzienTyg.AddDays(7).ToString("dd/MM/yyyy ");
return View();
}
[NonAction]
public ActionResult Next()
{
terminarz.pierwszyDzienTyg = terminarz.pierwszyDzienTyg.AddDays(7);
terminarz.ostatniDzienTyg = terminarz.ostatniDzienTyg.AddDays(-7);
return View("index");
}
}
my model
public partial class Terminarz
{
public DateTime aktualnaData { get; set; }
public DateTime pierwszyDzienTyg { get; set; }
public DateTime ostatniDzienTyg { get; set; }
public string nazwa { get; set; }
}
my view
#ViewBag.pierwszyDzien<br />
#ViewBag.ostatniDzien<br />
#ViewBag.wtf
#using (Html.BeginForm(FormMethod.Post))
{
#Html.ActionLink("dalej","Next", "Visits")
}
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
By default, all public methods in a controller can be called from an HTTP request. NonAction prevents the public method from being called from your form post. Remove the NonAction attribute from the Next method, and it should execute as expected.
You may also have to update your return to match a relative path something like this:
return View("~/Views/Index.cshtml");
Your form is also not being submitted. You are using a link inside of the form. Try this:
#using (Html.BeginForm("Next", "VisitsController", FormMethod.Post))
{
<button type="submit">Next</button>
}
I've got a populated entity filled with checkbox selector, few strings. that has to be built linearly(for each row) in a loop in a div structure.
The entity:
public class Hours
{
[Key]
public int SliceID { get; set; }
public string SliceName { get; set; }
public string Slice { get; set; }
public string StartTime { get; set; }
public string EndTime { get; set; }
public bool Selected { get; set; } //if slice is checked by user on search screen
}
The action which will gather all time slices for display:
public ActionResult Search_Times()
{
int iInstId = 1;
Test.Models.DataLayer db = new Test.Models.DataLayer();
Test.Models.TestDB context = new Models.TestDB();
IEnumerable<Test.Models.Hours> lst = db.GetSlices(context, iInstId).OrderBy(a => a.SliceID);
// ViewBag.SliceList = lst;
return View(lst);
}
I want to render those fields in a specific part of my body page along with some class/div formatting along the way.
For example, If I use EditorForModel :
in Main page:
#model IEnumerable<Test.Models.Hours>
#Html.EditorForModel()
in the Hours EditorTemplate:
#model Test.Models.Hours
<div>
#Html.CheckBoxFor(
x => x.Selected,
new {
#class = "jcf-unselectable",
id = HtmlHelper.GenerateIdFromName("cb_slice." + ViewData.TemplateInfo.GetFullHtmlFieldName(""))
}
)
// this should be a label too, made for example to show text from data.
#Html.DisplayTextFor(x => x.SliceName)
#Html.LabelFor(
x=> x.StartTime,
new {
#class = "info"
})
#Html.LabelFor(
x => x.EndTime,
new {
#class = "info"
})
</div>
The #Html.LabelFor in my case will only show the row's title and not the data (for="" in the source view after rendering), Unlike DisplayTextFor which will show the data but is only a generic text.
I need a way or to fix this current way, To manipulate the data from the model accordingly, Labels will show the data behind their field and I could generate the class,id needed(based on css/html required) inside that label in a loop.
What's the best way to do so, viewbags/templates/etc?
