ASP.Net MVC - model with collection, Submit

asp.net-mvc, c#, entity-framework

Solution

Try this insted of your `foreach`:

@for (int i = 0; i < Model.Refills.Count(); i++)
{
    @Html.Hidden("Refills[" + i + "].Id", Model.Refills[i].Id)
    <div class="editor-label">
        @Html.Label("Refills[" + i + "].RXNumber", Model.Refills[i].RXNumber)
    </div>
    <div class="editor-field">
        @Html.Editor("Refills[" + i + "].RXNumber")
    </div>     
}

Problem

I have a Model that looks like ``` public class Patient { private ICollection<Refill> _refills = new List<Refill>(); public int Id { get; set; } public string FirstName { get; set; } public virtual ICollection<Refill> Refills { get { return _refills; } set { _refills = value; } } } public class Refill { public int Id { get; set; } public RefillActivityStatus RefillActivityStatus { get; set; } public DateTime? RefillDate { get; set; } public RefillType RefillType { get; set; } public string RXNumber { get; set; } } ``` Here is what I am trying to do. I would like to Populate these in the View and when the user clicks save changes. I would like Entity Framework to save. The problem I am having is in the View I do this ``` @foreach (var m in Model.Refills) { @Html.HiddenFor(model=>m.Id) <div class="editor-label"> @Html.LabelFor(model => m.RXNumber) </div> <div class="editor-field"> @Html.EditorFor(model => m.RXNumber) </div> } ``` I am trying to do in the Controller something like this ``` [HttpPost] public ActionResult Details(Patient patient) { Patient p = db.Patients.Find(patient.Id); db.Entry(p).State = EntityState.Modified; db.Entry(p).CurrentValues.SetValues(patient); // Would include Refill changes too but it doesn't db.SaveChanges(); return View(p); } ``` However, Refills doesn't propagate on HttpPost. It is just empty, what do I need to do to fix it?
