Does ASP.NET MVC offer any simple way to get model binding to work when you have model classes that inherit from others?
In my scenario I have a
View that is strongly typed to List<Person>.
I have a couple of classes that inherit from Person, namely PersonTypeOne and PersonTypeTwo.
I have three strongly typed partial views with names that match these class names (and render form elements for the properties of their respective models).
This means that in my main
View I can have the following code:
<% for(int i = 0; i < Model.Count; i++)
{
Html.RenderPartial(Model[i].GetType().Name, Model[i]);
} %>
This works well, apart from when the user submits the form the relevant
controller action method just gets a List<Person>, rather than a list of Person, PersonTypeOne and PersonTypeTwo.
This is pretty much as expected as the form submission doesn't contain enough information to tell the default model binder to create any instances of PersonTypeOne and PersonTypeTwo classes.
So, is there any way to get such functionality from the default model binder?
