    <p>In a MVC project am trying to create a view which has the Title from a parent table and the subsequent list below it from its related Child table.</p> <p>I pulled the tables into the project using Entity Framework and in the controllers namespace created the follwing Viewmodel:</p> <pre><code>public class ServicesViewModel { public ServicesViewModel(List&lt;ServiceGroup&gt; servicegroups, List&lt;Service&gt; services) { this.ServiceGroups = servicegroups; this.Service = services; } public List&lt;ServiceGroup&gt; ServiceGroups { get; set; } public List&lt;Service&gt; Service { get; set; } } </code></pre> <p>Then in the controller Actionresult I did this:</p> <pre><code> public ActionResult Index() { var servicegroups = _db.ServiceGroupSet.ToList(); var services = _db.ServiceSet.ToList(); return View(new ServicesViewModel(servicegroups,services)); } </code></pre> <p>..And in the View did this:</p> <blockquote> " %> <p>Other html code etc..</p> </blockquote> <pre><code>&lt;% foreach (var m in Model.ServiceGroups) { %&gt; &lt;strong&gt;&lt;ul&gt; &lt;%= m.ServiceGroupName %&gt;&lt;/ul&gt;&lt;/strong&gt; &lt;% foreach (var item in Model.Service) { %&gt; &lt;li&gt; &lt;%= item.ServiceDescription %&gt;&lt;/li&gt; &lt;% } %&gt; &lt;% } %&gt; </code></pre> <p>It all wires up ok but runs ALL child records for each parent record. I have not figured how to put that parameter which filters into the view.</p> <p>I tried a linq query in the controller but can't seem to find the foreign key field in the intellisense.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
