Display data from multiple models in one view

Question

In the MVC 3 i want to display data from two models viz. Student and Enrollment into a single view. Student model

public class Student
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.None)]
        public int student_id { get; set; }

        public string student_name { get; set; }
        public string father { get; set; }
    }

Enrollment model

public class Enrollment
    {
        [Key]
        public int enrollment_id { get; set; }
        public string rollno { get; set; }
        public int student_id { get; set; }
        public string registration_no { get; set; }
        public date registration_date { get; set; }
}

My ViewModel looks like this

 public class StudentEnrollmentViewModel
    {
        public Student_Info Student_Info { get; set; }
        public Enrollment_Info Enrollment_Info { get; set; }
        [Key]
        public int ID { get; set; }
}

How do I retrieve the data from the two model and assign it to a viewmodel so that I can display it in a view? I am using Repository Design Pattern.

You can use DynamicPage, Look into following example

We need to use a Dynamic view page. (More Information) Follow following steps:

Create DynamicViewPage type

public class DynamicViewPage : ViewPage
{
   public new dynamic Model { get; private set; }    
   protected override void SetViewData(ViewDataDictionary viewData)
    {
        base.SetViewData(viewData);
        Model =  ViewData.Model;
    }`
}

Your Controller will look like

public ActionResult Account(string returnUrl)
{
    LoginModel loginmodel = null;//Initialize Model;
    RegistrationModel registrationModel = null ;//Initialize Model;
   // Any Extra logic
    return View("Account", new
    {
        Login = loginmodel,
        Register = registrationModel
    });
}

your View should Inherit from
```
Inherits="DynamicViewPage"
```

Now @Model.Login will give you Loginmodel

@Model.Register will give you RegisterModel

It should work as you expected.........

Thanks for your prompt reply... Will look into it :) – Bahdeng Jan 17 '12 at 12:58
I don't know about dynamic page. Because I would also like to use the viewmodel for CRUD operations. – Bahdeng Jan 17 '12 at 13:03
[http://lostechies.com/seanbiefeld/2010/06/23/dynamic-view-page-mvc-without-a-view-model/] will give you detail about Dynamic page. You Still can use CRUD operation as i assume data from different model will have different forms and different partial views. – Manas Jan 17 '12 at 13:06

Generally speaking, a controller would be responsible for contacting the model, storing the result set returned in a variable/array/struc that the view would consume. The model and view components/classes would be registered in the controller.

An example:

<event-handler event="display.institutions" access="public">            
    <notify listener="userInstitutionRights" method="getInstitutionsWithDataRightsNOXML" resultKey="request.institutions" />

    <view-page name="userNav" contentKey="request.userNav"/>
    <view-page name="userInstitutions" contentKey="request.pageContent"/>

    <announce event="assemblePage" />
</event-handler>

Event display.institutions is calling a model component userInstitutionRights and storing the result in a resultKey request.institutions and is including two view pages userNav, userInstitutions where the resultKey is available to each.
