I am using MVC 5,C#6 and VS 2017. As part of a model I am using to populate an MVC form I have a collection of type Admission where the class Admission is defined as
public class Admission
{
public DateTime AdmissionDate {get; set;}
public YesNo EmergencyAdmission {get: set;}
public DateTime DischargeDate {get; set;}
}
and YesNo is an enum. For simplification I have reduced the parent model to:
public class Patient
{
public int PatientID {get; set;}
public string PatientName {get; set;}
public List<Admission> Admissions {get; set;}
}
Admissions can be added dynamically on the client side. When the model is instantiated there is a single empty admission. Within the form I have
@foreach (var item in Model.Patient.Admissions)
{
Html.RenderPartial("Admission", item);
}
and in the partial view I then use:
@Html.EditorFor(m => m.AdmissionDate)
@Html.EditorFor(m => m.EmergencyAdmission)
@Html.EditorFor(m => m.DischargeDate)
I have editor templates to handle the dates and the YesNo enum.
My question is that I do not know how to bind the model on post for the list of admissions. If I use Request.Form and write my own binder the items for the partial view are being posted as arrays the array structure is lost on Request.Form. The only solutions I have seen involve use fairly complex JavaScript/jQuery functions. I want to do as much as possible server side. If I can solve this part then I have a way of dynamically adding additional admissions.
