I have the following code and I am trying to add the selected value to the model.SelectedPayCodes list everytime the user makes a selection from the dropdown and clicks on "Add"
CONTROLLER
[HttpPost]
public PartialViewResult AddPayCode(ReferralModel model, string SelectedPayCode)
{
var payCode = _employeeService.GetPayCodeById(Convert.ToInt32(SelectedPayCode));
model.Add(payCode);
return PartialView("_PayCodesPartial",model);
}
MODEL
public class ReferralModel
{
public Customer Customer { get; set; }
public Employee Employee { get; set; }
public List<PayCode> PayCodes { get; set; } // List of paycodes
public List<PayCode> PayCodesList { get; set; } // List of 'selected' paycodes
public SelectListItem SelectedPayCode { get; set; } // current selected paycode
public Referral Referral { get; set; }
public ReferralModel()
{
PayCodesList = new List<PayCode>();
}
// Step 3 - Add Paycode is done here.
public void Add(PayCode payCode)
{
PayCodesList.Add(payCode);
}
}
VIEW - Create.cshtml
#using (Ajax.BeginForm("AddPayCode", "Referral",
new AjaxOptions()
{
HttpMethod = "POST",
InsertionMode = InsertionMode.InsertAfter,
UpdateTargetId = "PayCodes",
}))
{
#Html.AntiForgeryToken()
#Html.ValidationSummary()
<!-- payCodes input-->
<div class="control-group col-lg-6">
<label class="control-label">Product</label>
<div class="controls">
<!-- Step 1 + Choose PayCode Here -->
#Html.DropDownListFor(model => model.SelectedPayCode, new SelectList(Model.PayCodes.ToList(), "Id", "Description"), "- Select -")
<input type="submit" value="Add" />
</div>
</div>
<!-- pay codes list -->
<div id="PayCodes">
</div>
}
VIEW - _PayCodesPartial.cshtml
#model Zenwire.Models.ReferralModel
#if (Model.PayCodesList != null)
{
foreach (var item in Model.PayCodesList)
{
string.Format("{0} - {1}", item.Code, item.Description);
}
}
The issue seems to be whenever a new item is added the list is empty again and does not retain it's previous selection.
Try this. I used Session State
public PartialViewResult AddPayCode(ReferralModel model, string SelectedPayCode)
{
var payCode = _employeeService.GetPayCodeById(Convert.ToInt32(SelectedPayCode));
model.PayCodesList = GetPayCodes();
model.Add(payCode);
Session["paycodes"] = model.PayCodesList;
return PartialView("_PayCodesPartial",model);
}
private List<PayCode> GetPayCodes()
{
List<PayCode> payCodes = (List<PayCode>)Session["paycodes"];
if (payCodes == null )
{
payCodes = new List<PayCode>();
Session["paycodes"] = paycode;
}
return payCodes;
}

I am having trouble in attempting to validate that a value has been chosen from a dropdown as follows:
Please Select Type
Keypad
Bill Pay
I have added the following details as part of my model:
[Required]
[StringLength(20, MinimumLength = 10)]
public string AccountType { get; set; }
When I post the form it is not highlighting the account type as not being filled out correctly. Any ideas why? I thought that the minimum length would have caught this
I will show validation for country below.
Model:
public class CountryModel
{
[Required(ErrorMessage="Country Required.")]
public int SelectedCountryId { get; set; }
public System.Web.Mvc.SelectList Countries { get; set; }
}
Controller:
public ActionResult Index(CountryModel model)
{
if (model.Countries == null)
{
model.Countries = new SelectList(new List<SelectListItem>()
{
new SelectListItem() { Text= "India", Value = "1" },
new SelectListItem() { Text= "Australia", Value = "2"}
},"Value","Text");
}
return View(model);
}
My View:
#model MVCControls.Models.CountryModel
#{
ViewBag.Title = "Index";
}
<h2>Dropdownlist Validation</h2>
#using (Html.BeginForm())
{
#Html.ValidationSummary()
#Html.Label("Country")
#Html.DropDownListFor(c => c.SelectedCountryId,Model.Countries, "..Select..")
#Html.ValidationMessage("Country is required.");
<input type="submit" name="name" value="Submit" />
}
Hope this helps
i have a radiobutton list in my create view.It is generated along with checkbox when selecting a dropdown.
#model IEnumerable<Admin.Models.viewmodel>
#foreach (var item in Model)
{
<label>
#Html.CheckBox("User", item.Selected, new { #id = "User" + item.Value, #value = item.Value })
#item.Text
</label>
<label>
#Html.RadioButton("rdnUser" + item.Value.TrimStart(), 1, item.IsSelected,new { #id = "rdnUser"})Primary
</label>
<label>
#Html.RadioButton("rdnUser" + item.Value.TrimStart(), 2,item.IsSelected, new { #id = "rdnUser"})Secondary
</label>
}
Iam saving the value of radiobutton to a field UserType in table UserMapping.
When I click on Edit link,I want to get the radiobutton selected according to database value..
Created a viewmodel to take values in checkbox and radiobutton.viewpartial viewmodel is:-
public class viewpartial : System.Web.Mvc.SelectListItem
{
public int Values { get; set; }
public bool IsSelected { get; set; }
}
The query is:-
var query = (from u in UserMapping
where u.UserID == id && u.Active == 1
join f in Financial on u.FinancialID equals f.FinancialID
into c
from d in c.DefaultIfEmpty()
select new viewpartialIFC
{
Text = d.FiName,
Value = SqlFunctions.StringConvert((double)d.FinancialID),
Selected = d.FinancialID == u.FinancialID ? true : false,
Values = u.UserType,
//IsSelected=???
}).Distinct().ToList();
what changes should i make in the query to get radiobutton selected..
This is a way that you can create a list of users and have the option to selected them (checkbox) and selected a particular role (radiobuttons):
ViewModel:
public class AdminViewModel
{
public int Id { get; set; }
public string Name { get; set; }
public bool isSelected { get; set; }
public int RadioValue { get; set; }
}
Controller:
public class HomeController : Controller
{
public ActionResult Index()
{
var data = GenerateViews();
return View(data);
}
[HttpPost]
public ActionResult Index(IList<AdminViewModel> data)
{
var selectedViews = data.Where(d => d.isSelected == true);
foreach (var selected in selectedViews)
{
//selected.Id;
//selected.RadioValue;
}
System.Diagnostics.Debugger.Break();
return View(data);
}
private IList<AdminViewModel> GenerateViews()
{
var output = new List<AdminViewModel>();
var rand = new Random();
for (var count = 1; count <= 10; ++count)
{
var newView = new AdminViewModel();
newView.Id = count;
newView.Name = "Name " + count.ToString();
newView.isSelected = false;
newView.RadioValue = rand.Next(1, 3);
output.Add(newView);
}
return output;
}
}
View:
#model IList<WebMVC3.Controllers.AdminViewModel>
<h2>Index</h2>
#using (Html.BeginForm())
{
//foreach (var item in Model)
for(var index = 0; index < Model.Count; ++index)
{
<div>
#Html.HiddenFor(m => Model[index].Id)
<label>
#Html.CheckBoxFor(m => Model[index].isSelected, Model[index].isSelected)
#Model[index].Name
</label>
<label>
#Html.RadioButtonFor(m => Model[index].RadioValue, 1)
Primary
</label>
<label>
#Html.RadioButtonFor(m => Model[index].RadioValue, 2)
Secondary
</label>
</div>
}
<input type="submit" value="Save" />
}
In Model:
public class DataViewModel
{
public IList<RowsCollection> Rows { get; set; }
public PaiementMethod PaiementMethod { get; set; }
}
public class RowsCollection
{
public string ID { get; set; }
public string Question { get; set; }
}
public enum PaiementMethod
{
Cash,
CreditCard,
}
In the Controller - Index ActionResult I have return my Model and render its into view page something like :
#model WebNexpo.Controllers.DataViewModel
#using (Html.BeginForm("Save", "page", FormMethod.Post, new { id = "saves"}))
{
foreach (var item in Model.Rows)
{
#Html.Label(item.Question)
<label for="paiement_cash">
Cash</label>
#Html.RadioButtonFor(m => m.PaiementMethod, "Cash", new { name = "paiement_cash" + #item.ID + "", id = "radioID" + #item.ID + "", Group = "Group" + #item.ID + "" })
<label for="paiement_cc">
Credit card</label>
#Html.RadioButtonFor(m => m.PaiementMethod, "CreditCard", new { name = "paiement_cc" + #item.ID + "", id = "radioname" + #item.ID + "", Group = "Group" + #item.ID + "" })
}
<input id="Saveser" type="submit" value="" class="button1" />
}
in submit form Action Event :
[HttpPost]
public ActionResult Save(DataViewModel model)
{
if (ModelState.IsValid)
{
//want to read all the label which selected rediobutton.
means suppose 4 question render on page and user have selected only 2
question of the answer.so How can accomplish here?
}
return RedirectToAction("Index", new {value = "123"});
}
There's some inconsistency here. You are rendering 2 radio buttons for each row so you probably want to reorganize your view model into:
public class DataViewModel
{
public IList<RowsCollection> Rows { get; set; }
}
public class RowsCollection
{
public string ID { get; set; }
public string Question { get; set; }
public PaiementMethod PaiementMethod { get; set; }
}
and then:
#model DataViewModel
#using (Html.BeginForm("Save", "page", FormMethod.Post, new { id = "saves"}))
{
for (var i = 0; i < Model.Rows.Count; i++)
{
<div>
#Html.HiddenFor(x => x.Rows[i].ID)
#Html.LabelFor(x => x.Rows[i].Question)
#Html.EditorFor(x => x.Rows[i].Question)
#Html.Label("payment_cash" + i, "Cash")
#Html.RadioButtonFor(m => m.Rows[i].PaiementMethod, "Cash", new { id = "payment_cash" + i })
#Html.Label("payment_cc" + i, "Credit card")
#Html.RadioButtonFor(m => m.Rows[i].PaiementMethod, "CreditCard", new { id = "payment_cc" + i })
</div>
}
<input id="Saveser" type="submit" value="" class="button1" />
}
and finally:
[HttpPost]
public ActionResult Save(DataViewModel model)
{
if (ModelState.IsValid)
{
// model.Rows[0].PaiementMethod will contain the selected payment method for the first question
// model.Rows[1].PaiementMethod will contain the selected payment method for the second question
// ...
}
return RedirectToAction("Index", new { value = "123" });
}
or if you want a single payment method you could keep your view model as is but then leave the radio buttons outside of the loop in your view. Like that:
#using (Html.BeginForm("Save", "page", FormMethod.Post, new { id = "saves" }))
{
for (var i = 0; i < Model.Rows.Count; i++)
{
<div>
#Html.HiddenFor(x => x.Rows[i].ID)
#Html.LabelFor(x => x.Rows[i].Question)
#Html.EditorFor(x => x.Rows[i].Question)
</div>
}
#Html.Label("payment_cash", "Cash")
#Html.RadioButtonFor(x => x.PaiementMethod, "Cash", new { id = "payment_cash" })
#Html.Label("payment_cc", "Credit card")
#Html.RadioButtonFor(x => x.PaiementMethod, "CreditCard", new { id = "payment_cc" })
<input id="Saveser" type="submit" value="" class="button1" />
}
I am new to MVC3
I am finding it difficult to create an dropdown.I have gone through all the other related questions but they all seem to be complex
I jus need to create a dropdown and insert the selected value in database
Here is what i have tried:
//Model class:
public int Id { get; set; }
public SelectList hobbiename { get; set; }
public string filelocation { get; set; }
public string hobbydetail { get; set; }
//Inside Controller
public ActionResult Create()
{
var values = new[]
{
new { Value = "1", Text = "Dancing" },
new { Value = "2", Text = "Painting" },
new { Value = "3", Text = "Singing" },
};
var model = new Hobbies
{
hobbiename = new SelectList(values, "Value", "Text")
};
return View();
}
//Inside view
<div class="editor-label">
#Html.LabelFor(model => model.hobbiename)
</div>
<div class="editor-field">
#Html.DropDownListFor( x => x.hobbiename, Model.hobbiename )
#Html.ValidationMessageFor(model => model.hobbiename)
</div>
I get an error:System.MissingMethodException: No parameterless constructor defined for this object
You are not passing any model to the view in your action. Also you should not use the same property as first and second argument of the DropDownListFor helper. The first argument that you pass as lambda expression corresponds to a scalar property on your view model that will hold the selected value and which will allow you to retrieve this value back when the form is submitted. The second argument is the collection.
So you could adapt a little bit your code:
Model:
public class Hobbies
{
[Required]
public string SelectedHobbyId { get; set; }
public IEnumerable<SelectListItem> AvailableHobbies { get; set; }
... some other properties that are irrelevant to the question
}
Controller:
public class HomeController: Controller
{
public ActionResult Create()
{
// obviously those values might come from a database or something
var values = new[]
{
new { Value = "1", Text = "Dancing" },
new { Value = "2", Text = "Painting" },
new { Value = "3", Text = "Singing" },
};
var model = new Hobbies
{
AvailableHobbies = values.Select(x => new SelectListItem
{
Value = x.Value,
Text = x.Text
});
};
return View(model);
}
[HttpPost]
public ActionResult Create(Hobbies hobbies)
{
// hobbies.SelectedHobbyId will contain the id of the element
// that was selected in the dropdown
...
}
}
View:
#model Hobbies
#using (Html.BeginForm())
{
#Html.LabelFor(x => x.SelectedHobbyId)
#Html.DropDownListFor(x => x.SelectedHobbyId, Model.AvailableHobbies)
#Html.ValidationMessageFor(x => x.SelectedHobbyId)
<button type="submit">Create</button>
}
I would create them as
Model:
public class ViewModel
{
public int Id { get; set; }
public string HobbyName { get; set; }
public IEnumerable<SelectListItem> Hobbies {get;set; }
public string FileLocation { get; set; }
public string HobbyDetail { get; set; }
}
Action
public ActionResult Create()
{
var someDbObjects= new[]
{
new { Id = "1", Text = "Dancing" },
new { Id = "2", Text = "Painting" },
new { Id = "3", Text = "Singing" },
};
var model = new ViewModel
{
Hobbies = someDbObjects.Select(k => new SelectListItem{ Text = k, Value = k.Id })
};
return View(model);
}
View
<div class="editor-label">
#Html.LabelFor(model => model.HobbyName)
</div>
<div class="editor-field">
#Html.DropDownListFor(x => x.HobbyName, Model.Hobbies )
#Html.ValidationMessageFor(model => model.HobbyName)
</div>
I'm working on a project using MVC3. I've first created a database (with the necessary constraints like PK and FK's) and added this database to my webapplicatie using the ADO.NET Entity Data Model. Everything seems to work fine but I can't make validation flexible. Here some code to clarify my question.
Edit: Added the View + correct models. This version is without importing a database but results the same.
--Models----
namespace CustomValidation.Models
{
public class Person : IValidatableObject
{
public int Id { get; set; }
[Required]
public String FirstName { get; set; }
[Required]

public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
if (String.IsNullOrEmpty(FirstName))
{
var field = new[] { "FirstName" };
yield return new ValidationResult("Firstname can't be null", field);
}
}
}
}

{
var field = new[] { "Streetname" };
yield return new ValidationResult("Streetname can't be null", field);
}
}
}

}
}

public class DBEntities : DbContext

public DbSet<Person> People { get; set; }
public DbSet<Address> Addressess { get; set; }
}
}
----Controller----

{
MasterModel Model = new MasterModel();
Model.Person = new Person();
Model.Addressess = new List<Address>();
Model.Addressess.Add(new Address());
Model.Addressess.Add(new Address());
return View(Model);
}
[HttpPost]
public ActionResult Index(MasterModel Model)
{
DBEntities _db = new DBEntities();
if (TryValidateModel(Model.Person))
{
_db.People.Add(Model.Person);

The problem (that I've noticed while debugging something like this) is that before the request gets inside of my action MVC first runs validators for your collection. So if I've only filled out Person in my form, while validating Model.Person it just return false (i guess because of the Required fields for Address) and so it will bounce back to my View.
I need to have some workaround that lets me decided which instances of my collection I want to validate in my action.
I've not been able to find any solution after a lot of time searching on the net.
I hope that someone can help me out.
PS. I'm quite a newbie with Visual Studio and MVC 3 so please don't be to hard on me :)
In order to validate sub-models of the model returned to your action, you need to apply TryValidateModel to the specific sub-model, and use the overload which includes the prefix for the model. If you look at your generated HTML, you will see that the Person fields have Person as a prefix, the first Address fields have Addressess[0] as the prefix, and the second Address fields have Addressess[1] as the prefix.
In addition, you must clear all model errors before invoking TryValidateModel (or the existing errors will cause TryValidateModel to return false).
Do the following:
[HttpPost]
public ActionResult Index(MasterModel model)
{
var reloadView = true;
// clear any existing errors
foreach (var key in ModelState.Keys)
ModelState[key].Errors.Clear();
if (TryValidateModel(model.Person, "Person"))
{
_db.People.Add(model.Person);
_db.SaveChanges();
reloadView = false;
for (var i = 0; i < model.Addressess.Count(); i++)
{
foreach (var key in ModelState.Keys)
ModelState[key].Errors.Clear();
if (TryValidateModel(model.Addressess[i], "Addressess[" + i.ToString() + "]"))
{
**// UPDATED CODE**
// add Person to Address model
model.Addressess[i].Person = model.Person;
_db.Addressess.Add(model.Addressess[i]);
_db.SaveChanges();
}
}
}
if (reloadView)
{
// clear and re-add all errors
foreach (var key in ModelState.Keys)
ModelState[key].Errors.Clear();
TryValidateModel(model);
return View(model);
}
else
{
// go to some other view
}
}
