I am creating a MVC application and I would like to pass data between views.
Here is my first view:
#model ClassDeclarationsThsesis.Models.AddGroupViewModel
#{
ViewBag.Title = "Add Groups";
}
<h2>Add Groups to subjects</h2>
#foreach (var user in Model.Users)
{
if (user.email.Replace(" ", String.Empty) == HttpContext.Current.User.Identity.Name)
{
if (user.user_type.Replace(" ", String.Empty) == 3.ToString() || user.user_type.Replace(" ", String.Empty) == 2.ToString())
{
using (Html.BeginForm("AddGroup", "Account", FormMethod.Post, new { #class = "form-horizontal", role = "form" }))
{
#Html.AntiForgeryToken()
<h4>Create new groups.</h4>
<hr />
#Html.ValidationSummary("", new { #class = "text-danger" })
<div class="form-group">
#{
List<SelectListItem> listItems1 = new List<SelectListItem>();
}
#foreach (var subject in Model.Subjects)
{
listItems1.Add(new SelectListItem
{
Text = subject.name,
Value = subject.name,
Selected = true
});
}
#Html.LabelFor(m => m.subject_name, new { #class = "col-md-2 control-label" })
<div class="col-md-10">
#Html.DropDownListFor(m => m.subject_name, listItems1, new { #class = "form-control" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(m => m.qty, new { #class = "col-md-2 control-label" })
<div class="col-md-10">
#Html.TextBoxFor(m => m.qty, new { #class = "form-control" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" class="btn btn-default" value="Submit" />
</div>
</div>
}
}
if (user.user_type.Replace(" ", String.Empty) == 1.ToString())
{
<p>You do not have enough permissions to enter this page. Contact the administrator.</p>
}
}
}
And my controller for this:
public ActionResult AddGroup(AddGroupViewModel model)
{
var entities = new ClassDeclarationsDBEntities1();
var model1 = new AddGroupViewModel();
model1.Subjects = entities.Subjects.ToList();
model1.Users = entities.Users.ToList();
// set your other properties too?
if (ModelState.IsValid)
{
return RedirectToAction("AddGroupsQty", "Account");
}
return View(model1);
}
And what I would like to achieve is to pass chosen item from dropdown list and this qty variable to AddGroupsQty View. How do I do this? In my controller of AddGroupsQty i have just a simple return of view so far.
You can pass the values using querystring.
return RedirectToAction("AddGroupsQty", "Account",
new { qty=model.qty,subject=model.subject_name);
Assuming your AddGroupsQty have 2 parameters to accept the quantity and subject
public ActionResult AddGroupsQty(int qty,string subject)
{
// do something with the parameter
// to do : return something
}
This will make browser to issue a new GET request with the values in query string. If you do not prefer to do that, you can use a server side temporary persistence mecahnism like TempData
TempData["qty"]=model.qty;
TempData["subject"]= model.subject_name;
return RedirectToAction("AddGroupsQty", "Account");
And in your AddGroupsQty action,
public ActionResult AddGroupsQty()
{
int qty=0;
string subjectName=string.Empty;
if(TempData["qty"]!=null)
{
qty = Convert.ToInt32(TempData["qty"]);
}
if(TempData["subject"]!=null)
{
subjectName = TempData["subject"];
}
// Use this as needed
return View();
}
If you want to pass these values from the ADdGroupsQty action to it's view, you can use either a view model or ViewBag/ViewData.

My Get function works fine and the search textbox shows but when I enter the user ID and click search, it goes directly to the post function. It is supposed to go to the Get function again to show the data . after the data shows and whether I selected from the checkboxes or not, I click save and then it is supposed to go to the POst function.
What am I doing wrong?
GET function :
[HttpGet]
public ActionResult Index(int? SearchId)
{
var viewModel = new UserViewModel();
if (SearchId != null)
{
var userDepartments = db.TBL_User_Dep_Access.Where(x => x.UserID == SearchId).Select(x => x.Dep_ID).ToList();
List<UserDepartmentViewModel> udeptVM = db.TBL_Department.Select(i => new UserDepartmentViewModel
{
Dep_Id = i.Department_ID,
Dep_Name = i.Department_Name,
IsChecked_ = userDepartments.Contains(i.Department_ID)
}).ToList();
var userPermissions = db.TBL_UserPermissions.Where(x => x.UserID == SearchId).Select(m => m.PermissionID).ToList();
List<UsrPERViewModel> upVM = db.TBL_Permissions.Select(i => new UsrPERViewModel
{
Id = i.PermissionID,
Name = i.PermissionName,
IsChecked = userPermissions.Contains(i.PermissionID)

viewModel.Departments = udeptVM;
viewModel.Permissions = upVM;

return View(viewModel);

BTW I removed most of the div in the view manually for simplicity, so it's okay if an opening or closing doesn't match.
As has been pointed out in the comments, in your code you have 1 form whereas to solve the problem you are talking about you need 2 forms. One form responsible for the search get request and the other responsible for the user post.
Here is a simple example of a search form and an update form on the same page.
The viewmodel and controller
using System.Web.Mvc;
namespace SearchAndSubmit.Controllers
{
public class UserViewModel
{
public int? Id { get; set; }
public string Name { get; set; }
}
public class HomeController : Controller
{
[HttpGet]
public ActionResult Edit(int? SearchId)
{
var viewModel = new UserViewModel();
if (SearchId != null)
{
viewModel.Id = SearchId;
//logic to search for user and create viewmodel goes here
}
return View(viewModel);
}
[ValidateAntiForgeryToken]
[HttpPost]
public ActionResult Edit(UserViewModel user_Pers)
{
//validation and create update logic goes here
return RedirectToAction("Index");
}
}
}
The view
#model SearchAndSubmit.Controllers.UserViewModel
#{
ViewBag.Title = "Edit/create user";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>#ViewBag.Title</h2>
#*This is the search form it does a get request*#
#using (Html.BeginForm("edit", "home", FormMethod.Get))
{
#Html.TextBox("SearchId", "", null, new { #id = "SearchId", #placeholder = "Search for...", #class = "form-control" })
<span>
<input value="Search" type="submit">
</span>
}
#*This is the form for updating the user it does a post*#
#using (Html.BeginForm("edit", "home", FormMethod.Post))
{
#Html.AntiForgeryToken()
#Html.HiddenFor(c => c.Id)
<p>
#Html.LabelFor(c => c.Name)
#Html.TextBoxFor(c => c.Name)
</p>
<div>
<input type="submit" value="Save" />
</div>
}
I want to pass data from view to controller but it always returns 0 and I don't know why.
I have to verify if the entred code is the same as passed in parametre of ActionResult Sortie() but I can't get the value entred in view.

}
</div>
</div>
Controller:
//Get Sortie
public ActionResult Sortie(Int64 id)
{
TempData["codebarre"] = id;
return View();
}
//Post Sortie
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Sortie()
{
var mvtrepository = new MvtRepository(db);
var c = Request.Form["codeB"];
if (Convert.ToInt64(TempData["codebarre"]) == Convert.ToInt64(c))
{
var mvtInsert = mvtrepository.InsertMvt(DateTime.Now, Convert.ToInt64(TempData["codebarre"]), 2);
return RedirectToAction("Traitement");
}
else
{
return View("Error");
}
}
Help please and thank you.
Do not access the Request.Form directly. Instead, your POST action should accept the ViewModel as parameter.
[HttpPost]
public ActionResult Sortie(ViewModel.DemandeViewModel postData) {
int c = postData.CodeBarre; // assuming CodeBarre is an int in the ViewModel
if ((int)TempData["codebarre"] == c) {
// ...
}
// ...
}
Also in your View, let MVC set the name attribute so the ViewModel can be bound correctly by the ModelBinder.
#Html.EditorFor(model => model.CodeBarre, new { htmlAttributes = new { #class = "form-control" } })
Because you have an Editor input for the CodeBarre, you do not need another hidden input for it. Remove the line
#Html.HiddenFor(model => model.CodeBarre)
This question already has answers here:
The ViewData item that has the key 'XXX' is of type 'System.Int32' but must be of type 'IEnumerable<SelectListItem>'

I checked all of the other questions about this and they all seemed to be a bit different so any help you could offer would be appreciated.
Your issue is right here:
catch
{
ViewBag.Message = "File upload failed!!";
return View(document);
}
When you run into an an error and the execution goes into the catch block, you are not setting the UserId property. Later your view looks for that property in this line:
#Html.DropDownList("UserId")
And since it cannot find it, it starts complaining. To fix it, you need to set the UserId property in the catch block as well. Having said that, a better question you may want to ask yourself is why you are ending up in the catch block? And since the block is a catch all block, you may have issues in your code anywhere in your try block.
The other issue is that once you have fixed the above, you will still have an issue because the UserId will be the name of the parameter submitted to the action method, not selectedName as you have in your action method.
I am maing an MVC application connected to Entity Framework. In my view I have a dropdown list. Code looks like this:
#{
ViewBag.Title = "ClassesPickGroup"; } #model ClassDeclarationsThsesis.Models.ClassesPickGroupViewModel
<h2>ClassesPickGroup</h2>
#foreach (var user in Model.users) {
if (user.email.Replace(" ", String.Empty) == HttpContext.Current.User.Identity.Name)
{
if (user.user_type.Replace(" ", String.Empty) == 3.ToString() || user.user_type.Replace(" ", String.Empty) == 2.ToString())
{
using (Html.BeginForm("ClassesPickGroup", "Account", FormMethod.Post, new { #class = "form-horizontal", role = "form" }))
{
#Html.AntiForgeryToken()
<h4>Generate summary views</h4>
<hr />
#Html.ValidationSummary("", new { #class = "text-danger" })
<div class="form-group">
#{
List<SelectListItem> listItems1 = new List<SelectListItem>();
foreach (var sub in Model.subjects)
{
if (sub.name.Replace(" ", String.Empty) == Model.subject_name.Replace(" ", String.Empty))
{
Model.subject_id = sub.class_id;
}
}
foreach (var group in Model.groups)
{
if (group.class_id == Model.subject_id)
{
listItems1.Add(new SelectListItem
{
Text = group.name,
Value = group.name,
});
}
}
}
#Html.LabelFor(m => m.selected_group, new { #class = "col-md-2 control-label" })
<div class="col-md-10">
#Html.DropDownListFor(m => m.selected_group, listItems1, new { #class = "form-control" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" class="btn btn-default" value="Submit" />
</div>
</div>
}
}
if (user.user_type.Replace(" ", String.Empty) == 1.ToString())
{
<p>You do not have enough permissions to enter this page. Contact the administrator.</p>
}
}
}
However, in my dropdown list I see wrong things. The number of elements is correct, but all the names are the same, all the names correspond to first matching 'group' to pick from model. What do I do wrong?
My controller looks like this:
public ActionResult ClassesPickGroup(ClassesPickGroupViewModel value)
{
ClassDeclarationsDBEntities1 entities=new ClassDeclarationsDBEntities1();
int subj_id=0;
ClassesPickGroupViewModel model=new ClassesPickGroupViewModel();
model.subject_name = value.subject_name;
foreach (var subject in entities.Subjects)
{
if(subject.name.Replace(" ",String.Empty)==value.subject_name.Replace(" ", String.Empty))
{
subj_id = subject.class_id;
}
}
model.groups = entities.Groups.ToList();
model.subjects = entities.Subjects.ToList();
model.users = entities.Users.ToList();
if (ModelState.IsValid)
{
return RedirectToAction("ClassesView", "Account");
}
else
{
model.groups = entities.Groups.ToList();
model.subjects = entities.Subjects.ToList();
model.users = entities.Users.ToList();
return View(model);
}
return View(model);
}
Apparently, adding groups does not work well, groups are not unique (however in database they are). What is wrong with it?
You are not passing any value for model.subject_id from controller. That is why the last value is kept saved for taking names it only hits the same subject_id

I'm new to asp.net and this is my first application.
I'm developing an application that manages insurance requests. The model Request contains a file upload. the addDemand (adds a request)requires a member(adherent) to be logged in. Every time I try to run the addDemande I get the error:
The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[Mutuelle.Domain.Entities.Demande]', but this dictionary requires a model item of type 'Mutuelle.Domain.Entities.Demande'.
Here's the controller:
public ActionResult AddDemande()
{
Demande demande = new Demande();
return View(demande);
}
[HttpPost]
public ActionResult AddDemande([Bind(Exclude = "fichier")]Demande demande, HttpPostedFileBase fichier)
{
try
{
if (!ModelState.IsValid)
{
return View();
}
else
{
BinaryReader fichierReader = new BinaryReader(fichier.InputStream);
byte[] fichiers = fichierReader.ReadBytes(fichier.ContentLength);
demande.fichier = fichiers;
AdherentDService adherentService = new AdherentDService();
Adherent adherent = (Adherent)Session["logedAd"];
demande.nomBeneficiaire = adherent.nom;
demande.eMailBeneficiaire = adherent.eMail;
demande.beneficiare = adherent;
adherent.listDemandes.Add(demande);
adherentService.Updateadherent(adherent);
demande.beneficiare = adherent;
adherentService.CreateaDemande(demande);
Session.Remove("logedAd");
Session.Add("logedAd", adherent);
return RedirectToAction("Demandes");
}
}
catch
{
return RedirectToAction("Index", "Home");
}
}
And here's the View:
model Mutuelle.Domain.Entities.Demande
#{
ViewBag.Title = "AddDemande";
