Multiple Models in Single View in MVC 4 / 5

Question

Hello I am trying to create a web application mvc asp dotnet 4 razor. I would like to put multiple views in a model. To make it clearer here is my Model my eyesight and my controller. My Model: two tables : Malades and Consultations public DbSet Malades { get; set; } public DbSet Consultations { get; set; } My Controller: public ActionResult Index() { if (User.Identity.IsAuthenticated) { return View(); } return RedirectToAction(Login Account); } My ContentViewModel: public class ViewModelProfil { public List Malades { get; set; } public List Consultations { get; set; } } My view: ... @foreach(var item in Model.Malades) { @Html.DisplayNameFor(modelItem => item.Nom) } @foreach(var item in Model.Consultations) { @Html.DisplayNameFor(modelItem => item.Nombre) } ... I want to clarify that the data is not manually integrate into the database but it is a user who filled out a form for the data to be stored in the database. I did several searches su google but I fall on tutorials that show how to do it perfectly but the data are filled manually (Example : http://www.codeproject.com/Articles/687061/Multiple-Models-in-a-View-in-ASP-NET-MVC-MVC ). Thank you for your help.

Hi Can I understand your question. Because what you are doing is perfectly correct. You will create a viewmodel for handling multiple model in a single view.

Yes keyur  I'm agree with you. i think i must modifies my repository to have a correct code. i'ts the question that i ask in this page. i dont know how to do this. i tried with (in my repository) : public List GetMalades() { Malade malade = db.Malades. FirstOrDefault (p => p.UserProfile.UserName == User.Identity.Name); return new List { new Malade () { MaladeId = malade.Id Name = malade.Name } }; }. But like we can see it's not the solution besause i have the firts data of my table Malades who is display in my single view. Thank you for you help.

Hi Pradeep Shet. Let me give you more details. Thank you for your quick answer. To make it clearer here is my Model my controller my ContentModelView my view and my Repository : My Model: two tables : Malades and Consultations public DbSet Malades { get; set; } public DbSet Consultations { get; set; } My Controller: public ActionResult Index() { if (User.Identity.IsAuthenticated) { ContentModelView vm = new ContentModelView (); vm.all Malades = _repository.Get Malades (); vm.all Consultations = _repository.Get Consultations (); return View(vm); } return RedirectToAction(Login Account); } My ContentViewModel: public class ContentModelView { public List Malades { get; set; } public List Consultations { get; set; } } My view: ... @foreach(var item in Model.Malades) { @Html.DisplayNameFor(modelItem => item.Nom) } @foreach(var item in Model.Consultations) { @Html.DisplayNameFor(modelItem => item.Nombre) } My Repository (repository.cs) : public List GetMalades() { return new List { new Malade () { Id = 1  Name =  something  } new Malade () { Id = 2  Name =  something  } new Malade () { Id = 3  Name =  something  } new Malade () { Id = 4  Name =  something  } }; } public List Consultation > Get Consultation s() { return new List Consultation > { new Consultation () { Id = 1  Name =  something } new Consultation () { Id = 2  Name =  something  } new Consultation () { Id = 3  Name =  something  } new Consultation () { Id = 4  Name =  something  } }; } In me repository.cs we can see that my two tables (Malade and Consultation) are filled manually It's not that i want. In my projet the table of my Model (Malade and Consultation) are filled by a form ho are in a view. i try this but he have some mistake. let me show you : for the table Malade (i do the same thing for Consultation so i have the same error)! public List GetMalades() { Malade malade = db.Malades.Single(p => p.UserProfile.UserName == User.Identity.Name); return new List { new Malade () { MaladeId = malade.Id Name = malade.Name } }; }. This this solution that a do when i filled the first time the table Malades there are not problem (no problem to save it in the database no problem to display him in my ViewModel (thid single view who can show multiples models)). But when i filled the table Malades by my form the second time there is an error ( no problem to save it in the database but it have a problem to display him in my ViewModel ) with Single ( Malade malade = db.Malades.Single(p => p.UserProfile.UserName == User.Identity.Name);) i think it can show only information when the table are filled one time. So Pradeep Shet this is my really problem. Thank you too much for your answer.

Hello You can create ViewModel and put all models which you need in single view.also you can create Partialview in your view which separtes your view file as well. Hope this will help
