I'm having problems making the Html.Editor rendering the desire HTML.
Here is the scenario:
// assign the value
ViewBag.BeginDate = seaBeginEnd.beginDate;
//View
#Html.Editor("Begin", ViewBag.BeginDate as DateTime?)
//HTML Source
<div class="editor-field">
<input class="text-box single-line" id="Begin" name="Begin" type="text" value="" />
</div>
I was specking to see a value of 1/19/2011 12:00:00 AM which is the value of ViewBag.BeginDate, any insights.
Thanks for your help!

You cannot expect such thing by passing Begin as first parameter to the Html.Editor helper. The second parameter doesn't do what you think it does. It simply sends some additional view data to the editor template but the original value you are binding to is called Begin so that's what you should assign a value to. Like this:
public ActionResult Index()
{
ViewBag.Begin = DateTime.Now;
return View();
}
and then:
#Html.Editor("Begin")
Obviously every time I see someone using ViewBag/ViewData and not strongly typed helpers I feel in the obligation to recommend view models and strongly typed helpers. Example:
Model:
public class MyViewModel
{
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public DateTime Date { get; set; }
}
Controller:
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new MyViewModel
{
Date = DateTime.Now
});
}
}
and the corresponding strongly typed view:
#model AppName.Models.MyViewModel
#Html.EditorFor(x => x.Date)

I am new to MVC. I am facing problem to get Date of birth value from view into controller by using view model. I am using view model for getting form values and getting all other textboxes values. But I always get null value for date.
My view model is like this.
public class Student
{
[Required(ErrorMessage = "Date of birth is required")]
[DataType(DataType.Date), DisplayFormat(ApplyFormatInEditMode = true,DataFormatString = "{0:dd/MM/yy}",ConvertEmptyStringToNull=false)]
public DateTime? DateOfBirth { get; set; }
}
My controller which is called after form posting is:
[HttpPost]
public ActionResult StudentPersonalReg(Student stud)
{
DateTime? dateofbirth = stud.DateOfBirth;
return RedirectToAction("Registration");
}
My view is
#model eEducation.Models.UserModel.Student
#Html.TextBoxFor(x => x.DateOfBirth)
#Html.ValidationMessageFor(x => x.DateOfBirth)
Problem is that I always get null value for date in controller.
I have also tried setting DateTime.Now to the viewmodel when I am calling the view from controller.
I am not using strongly typed view.
Please help me in this regard.
I am passing my model to view by controller method
public ViewResult Registration()
{
var db = new eEducationEntities();
List<CountryMaster> queryCountry = db.CountryMasters.ToList();
List<StateMaster> queryState = db.StateMasters.ToList();
Student stds = new Student();
stds.Countries = queryCountry;
stds.States = queryState;
stds.DateOfBirth = DateTime.Now;
return View("~/Views/UserSection/StudentRegistration.cshtml", stds);
}
You need to be using a Html.BeginForm() on your view model. You can even specify the controller action it posts back to.
#model eEducation.Models.UserModel.Student
#using (Html.BeginForm("StudentPersonalReg", "ControllerName")) {
#Html.ValidationSummary(true)
#Html.TextBoxFor(x => x.DateOfBirth)
#Html.ValidationMessageFor(x => x.DateOfBirth)
<p>
<input type="submit" value="Submit" />
</p>
}
I have an Index view in an MVC3 application with a #model which is ienumerable. In this model I have an accountID which I want to use to populate my dropdownlist in the view filter with the accounts so that the user will be able to filter for accounts.
Which is the best way to achieve this?
Thanks in advance.
This is the view:
#model IEnumerable<MoneyAdmin.Model.ContaAReceber>
#{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
#Html.Partial("_SubmenuAdmin")
<div class="tituloCadastro">
Lista de Contas a Receber
</div>
<div class="buttonContainer novo">
#Html.ActionLink("Nova Conta", "Create")
</div>
<div class="filtros">
#using (Html.BeginForm()) {
<div class="filterField">
<label>Data Inicial:</label>
#Html.TextBox("dataInicial", #DateTime.Now.ToShortDateString())
</div>
<div class="filterField">
<label>Data Final:</label>
#Html.TextBox("dataFinal", #DateTime.Now.ToShortDateString())
</div>
<div class="filterField">
<label>Tipo de Conta:</label>
#Html.DropDownList("contaID")
</div>
<input type="submit" value="Atualizar" />
}
</div>
And the controller method:
public ViewResult Index(string dataInicial, string dataFinal, string contaID)
{
var crs = from cr in db.contasareceber.Include("contas")
select cr;
if (!string.IsNullOrEmpty(dataInicial) && !string.IsNullOrEmpty(dataFinal))
{
DateTime di = DateTime.Parse(dataInicial);
DateTime df = DateTime.Parse(dataFinal);
crs = crs.Where(cr => cr.dataPagamento >= di && cr.dataPagamento <= df);
}
return View(crs.ToList());
}
I think the best way to achieve what you're after would be to use a ViewModel. You'd load the stuff you want to display in your View through this. So you'd create a dropdownlist with your accountlist which will be loaded in your controller. You'll also have your IEnumerable ContaAReceber in there which will also be loaded in your controller. Then your controller will pass the ViewModel to the View. Sort of hard to give you an exact answer as you haven't shown us your Model. But you can use this as a guide.
ViewModel:
public class ContaAReceberViewModel
{
public int ContaAReceberID {get;set;}
public List<SelectListItem> ContaAReceberList {get;set;}
public IEnumerable<ContaAReceber> ContaAReceber {get;set;}
}
Dropdownlist in Razor View :
#Html.DropDownListFor(m => m.ContaAReceberID, Model.ContaAReceberList)
You can use ViewBag instead of creating a ViewModel to transport your data.
ViewModel
public class ContaFilterViewModel
{
public int Id { get; set; }
public string Name { get; set; }
}
ActionResult
public ViewResult Index(string dataInicial, string dataFinal, string contaID)
{
var crs = from cr in db.contasareceber.Include("contas")
select cr;
// select uniquely all available Contas
ViewBag.UniqueContas = crs.Select(x => new ContaFilterViewModel() { Id = x.ContaId, Name = x.ContaName}).Unique().ToList();
if (!string.IsNullOrEmpty(dataInicial) && !string.IsNullOrEmpty(dataFinal))
{
DateTime di = DateTime.Parse(dataInicial);
DateTime df = DateTime.Parse(dataFinal);
crs = crs.Where(cr => cr.dataPagamento >= di && cr.dataPagamento <= df);
}
// return filtered Contas
return View(crs.ToList());
}
View
<div class="filterField">
<label>Tipo de Conta:</label>
#Html.DropDownList("contaID", new SelectList((ContaFilterViewModel)ViewBag.UniqueContas, "Id, "Name"))
</div>
Thanks for everyone!
I found the answer as like this.
Populate the viewbag in the controller like that:
ViewBag.Contas = new SelectList(db.contas, "contaID", "nome");
Then use it in the dropdownlist like that:
#Html.DropDownList("Contas");
Simple and it works!
Thanks for everyone!
So I have the following code:
#model Project.Models.ViewModels.SomeViewModel
#using (Html.BeginForm("SomeAction", "SomeController", new { id = Model.Id}))
{
for(int i = 0; i < Model.SomeCollection.Count(); i++)
{
#Html.HiddenFor(x => Model.SomeCollection.ElementAt(i).Id)
<div class="grid_6">
#Html.TextAreaFor(x => Model.SomeCollection.ElementAt(i).Text, new { #style = "height:150px", #class = "grid_6 input" })
</div>
}
<div class="grid_6 alpha omega">
<input type="submit" value="Next" class="grid_6 alpha omega button drop_4 gravity_5" />
</div>
}
On the Controller Side I have the following:
[HttpPost]
public ActionResult SomeAction(int id, SomeViewModel model)
{
return PartialView("_SomeOtherView", new SomeOtherViewModel(id));
}
My View Model is set up like this:
public class SomeViewModel
{
public SomeViewModel()
{
}
public IEnumerable<ItemViewModel> SomeCollection { get; set; }
}
public class ItemViewModel{
public ItemViewModel(){}
public int Id {get;set;}
public string Text{get;set;}
}
The SomeCollection is always empty when SomeAction if performed. What do I have to do in order to show the updated values by users. Text Property and Id field.
Use an EditorTemplate
Create an EditorTemplate folder under your Views/YourcontrollerName and create a view with name ItemViewModel.cshtml
And Have this code in that file
#model Project.Models.ViewModels.ItemViewModel
<p>
#Html.EditorFor(x => x.Text)
#Html.HiddenFor(x=>x.Id)
</p>
Now from your Main view, call it like this
#model Project.Models.ViewModels.SomeViewModel
#using (Html.BeginForm("SomeAction", "Home", new { id = Model.Id}))
{
#Html.EditorFor(s=>s.SomeCollection)
<div class="grid_6 alpha omega">
<input type="submit" value="Next" class="grid_6 alpha omega button drop_4 gravity_5" />
</div>
}
Now in your HTTPPOST method will be filled with values.
I am not sure what you want to do with the values( returning the partial view ?) So not making any comments about that.
I am not sure you have posted all the code.
Your action method does not do anything, since it returns a partial view (for some reason from a post call, not an ajax request) using a new model object.
Your effectively passing a model back to the action and then discarding it, and returning a new model object. This is the reason your collection is always empty, its never set anywhere.
Well, for one thing, why do you have both the model AND id, a property of model, sent back to the controller? Doesn't that seem a bit redundant? Also, you're using a javascript for loop in the view. It'd be much easier to just use #foreach.
Anyway, your problem is that when you tell an action to accept a model, it looks in the post for values with keys matching the names of each of the properties of the model. So, lets say we have following model:
public class Employee
{
public string Name;
public int ID;
public string Position;
}
and if I'm passing it back like this:
#using(Html.BeginForm("SomeAction", "SomeController"))
{
<input type="text" name = "name" [...] /> //in your case HtmlHelper is doing this for you, but same thing
<input type="number" name = "id" [...] />
<input type="submit" name = "position" [...] />
}
To pass this model back to a controller, I'd have to do this:
Accepting a Model
//MVC matches attribute names to form values
public ActionResult SomethingPosted(Employee emp)
{
//
}
Accepting a collection of values
//MVC matches parameter names to form values
public ActionResult SomethingPosted(string name, int id, string postion)
{
//
}
or this:
Accepting a FormCollection
//same thing as first one, but without a strongly-typed model
public ActionResult SomethingPosted(FormCollection empValues)
{
//
}
So, here's a better version of your code.
Your new view
#model Project.Models.ViewModels.SomeViewModel
#{
using (Html.BeginForm("SomeAction", "SomeController", new { id = Model.Id}))
{
foreach(var item in Model)
{
#Html.HiddenFor(item.Id)
<div class="grid_6">
#Html.TextAreaFor(item.Text, new { #style = "height:150px", #class = "grid_6 input" })
</div>
}
<div class="grid_6 alpha omega">
<input type="submit" value="Next" class="grid_6 alpha omega button drop_4 gravity_5" />
</div>
}
}
Your new action
[HttpPost]
public ActionResult SomeAction(int Id, string Text)
{
//do stuff with id and text
return PartialView("_SomeOtherView", new SomeOtherViewModel(id));
}
or
[HttpPost]
public ActionResult SomeAction(IEnumerable<ItemViewModel> SomeCollection) //can't use someviewmodel, because it doesn't (directly) *have* members called "Id" and "Text"
{
//do stuff with id and text
return PartialView("_SomeOtherView", new SomeOtherViewModel(id));
}
I have two classes, Vat and Product. Product has a property of IVat. I am trying to use editor templates in MVC to display a dropdown list of all the Vat objects when creating/editing a Product. For the dear life of me I cannot get this working.
I have the following code which displays the dropdown but it does not set the Vat for the Product when the form gets submitted.
Controller:
IList<IVatRate> vatRates = SqlDataRepository.VatRates.Data.GetAllResults();
ViewBag.VatRates = new SelectList(vatRates, "Id", "Description");
Add.cshtml
#Html.EditorFor(model => model.VatRate.Id, "VatSelector", (SelectList)ViewBag.VatRates)
VatSelector.cshtml
#model SelectList
#Html.DropDownList(
String.Empty /* */,
(SelectList)ViewBag.Suppliers,
Model
)
I would be grateful if anyone can shed some light on this or even point me to a good example on the web somewhere...I have been stuck with this for quite a few days now.
I would use strongly typed views and view models as it makes things so much easier rather than ViewBag.
So start with a view model:
public class VatRateViewModel
{
public string SelectedVatRateId { get; set; }
public IEnumerable<IVatRate> Rates { get; set; }
}
then a controller:
public class HomeController: Controller
{
public ActionResult Index()
{
var model = new VatRateViewModel
{
Rates = SqlDataRepository.VatRates.Data.GetAllResults()
};
return View(model);
}
[HttpPost]
public ActionResult Index(VatRateViewModel model)
{
// model.SelectedVatRateId will contain the selected vat rate id
...
}
}
View:
#model VatRateViewModel
#using (Html.BeginForm())
{
#Html.DropDownListFor(
x => x.SelectedVatRateId,
new SelectList(Model.Rates, "Id", "Description")
)
<input type="submit" value="OK" />
}
And if you wanted to use editor template for the VatRateViewModel you could define one in ~/Views/Shared/EditorTemplates/VatRateViewModel.cshtml:
#model VatRateViewModel
#Html.DropDownListFor(
x => x.SelectedVatRateId,
new SelectList(Model.Rates, "Id", "Description")
)
and then whenever somewhere you have a property of type VatRateViewModel you could simply:
#Html.EditorFor(x => x.SomePropertyOfTypeVatRateViewModel)
which would render the corresponding editor template.
i have designed a view in asp .net mvc3 off course registration form. This is very simple form having name ,father name , qualification and a submit button , after pressing submit button i want to display information by using another view. please suggest me how can i send information from one view to another view.
my controller class is :
namespace RegistrationForm.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
// ViewBag.Message = "Welcome to ASP.NET MVC!";
//return View();
return RedirectToAction("registrationView");
}
public ActionResult About()
{
return View();
}
public ActionResult registrationView()
{
return View();
}
}
}
my view is :
#{
Layout = null;
}
registrationView
Enter Name
</td>
<tr>
<td>
Enter Father Name
</td>
<td>
<input type="text" name="fname" id="fname" />
</td>
<tr>
<td>
Enter Qualification
</td>
<td>
<input type="text" name="qly" id="qly" />
</td>
</tr>
</table>
<input type="submit" value="submit" />
</div>
well, we faced this problem before, and the best way to get this to work was to define a model that this page will work with, then use this model object when posting back, or redirecting to another view.
for your case, you can simply define this model in your Models folder
ex: RegistrationModel.cs file, and define your required properties inside.
after doing so, you will need to do 2 more steps:
1- in your GET action method, create a new RegistrationModel object, and provide it to your view, so instead of:
return View();
you will need something like:
var registrationModel = new registrationModel();
return View(registrationModel);
2- Use this model as a parameter in your POST Action method, something like
[HttpPost]
public ActionResult registrationView(RegistrationModel model)
{
// your code goes here
}
but don't forget to modify the current view to make use of the provided model. a time-saver way would be to create a new dummy View, and use the pre-defined template "Create" to generate your View, MVC will generate the properties with everything hooked up. then copy the generated code into your desired view, and omit any unneeded code.
this is a Pseudo reply. if you need more code, let me know
<% using Html.Form("<ActionName>") { %>
// utilize this HtmlHelper action to redirect this form to a different Action other than controller that called it.
<% } %>
use ViewData to store the value.
just remember that it will only last per one trip so if you try to call it again, the value would have been cleared.
namespace RegistrationForm.Controllers { public class HomeController : Controller { public ActionResult Index() { // ViewBag.Message = "Welcome to ASP.NET MVC!";
ViewData["myData"] = "hello world";
//return View();
return RedirectToAction("registrationView");
}
public ActionResult About()
{
return View();
}
public ActionResult registrationView()
{
// get back my data
string data = ViewData["myData"] != null ? ViewData["myData"].ToString() : "";
return View();
}
}
And you can actually usethe ViewData value on the html/aspx/ascx after redirect to the registrationView.
For example on the registrationView.aspx:
<div id="myDiv">
my data was: <%= ViewData["myData"] %>
</div>
You could simply in you method parameter list declare the parameters with the name of the controls. For example:
The control here has an id "qly"
<input type="text" name="qly" id="qly" />
Define your method parameter list as following:
public ActionResult YourMethod(string qly)
{
//simply pass your qly to another view using ViewData, TempData, or ViewBag, and use it in the desired view
}
You should use TempData which was made exactly for it, to persist values between actions.
This example is from MSDN (link above):
public ActionResult InsertCustomer(string firstName, string lastName)
{
// Check for input errors.
if (String.IsNullOrEmpty(firstName) ||
String.IsNullOrEmpty(lastName))
{
InsertError error = new InsertError();
error.ErrorMessage = "Both names are required.";
error.OriginalFirstName = firstName;
error.OriginalLastName = lastName;
TempData["error"] = error; // sending data to the other action
return RedirectToAction("NewCustomer");
}
// No errors
// ...
return View();
}
And to send data to the view you can use the model or the ViewBag.
