Question

I have an ASP.NET MVC 4 C# application and I want to display data from 3 different models in one view.

The schemas are related via foreign keys like this:

Model A | Model B | Model C
ID      | ID      | ID
          A_ID    | B_ID

In View for model A, I want to be able to to display data that is linked in B and C.

Right now, in the View for Model A (Details) I can do:

@model Application.Models.A

@foreach (var b Model.B)
    {
        @Html.DisplayFor(modelB => B.Title)
        <br />
    }

I want to be able to then do:

@foreach (var b Model.B)
    {
        @Html.DisplayFor(modelB => B.Title)

        @foreach (var c Model.B.C)
        {
            @Html.DisplayFor(modelC => C.Title)
            <br />
        }

        <br />
    }

You can do this in ruby on rails, how can I do this in MVC 4?

Answer 1

I figured it out.

I had the models, controllers and relationships setup correctly. I just needed to modify my view to the following:

@foreach (var b in Model.Bs)
    {
        @Html.DisplayFor(B => b.Title)
        <br />
        foreach (var c in b.Cs)
        {
            @Html.DisplayFor(C => c.Title)
            <br />
        }
    }

Thanks.
