Partial View with variable model type

Question

Update from Travis Answer :

public interface IEntity
{
    int Id{get;set;}
    string Name{get;set;}
}
public class Vehicule:IEntity
{
    public int Id{get;set;}
    public string Name{ get; set; }
}
public class Sector:IEntity
{
    public string Id{ get; set; }
    public string Name{ get; set; }
}

and this model for the main View :

public class MainViewModel
{
    public Vehicule Vehicule{ get; set; }
    public Sector Sector{ get; set; }
}

Now I want to implement a form for each entity (It will be a modal form but it's not the point). It will be more complex, but for the exemple it's just :

@Html.TextBoxFor(m=>m.Name)
//etc...

I'm trying to implement the interface with generic type but I don't really understand how to do, especially generic type.

Now I have @model GenericViewModel<IEntity> in my partial view and MainViewModel in my view.

How to pass the model to partial view with the generic type?

@Html.RenderPartial("_PartialView",????)

I think there is something missing in MainViewModel but I tried a lot of things without success.

It would be very helpful if you could tell me what I'm missing.

Thanks

Use an interface to expose properties or behaviors across different types.

public interface IEntity
{
    string PropertyA;
    string PropertyB;
    string PropertyC;
}

Then have each entity inherit this interface

public class Entity1 : IEntity { ... }
public class Entity2 : IEntity { ... }
public class Entity3 : IEntity { ... }

And now in your view you can expose the interface properties to the entities

@model GenericModelType<IEntity>
