Body
I have had the same issue in one of my applications. I solved it by creating a custom IModelBinder inheriting from DefaultModelBinder and registered it with the particular type I'm binding. The trick is to use <code>session.Load<></code> which only creates a typed reference to the entity without querying the database. (<a href="http://ayende.com/blog/3988/nhibernate-the-difference-between-get-load-and-querying-by-id" rel="nofollow">Read more about session.Load here in Ayende's blog</a>) <pre><code>/// <summary> /// Base for binding references. Usually displayed in dropdowns /// </summary> public class ReferenceBinder<T> : DefaultModelBinder where T : class { private readonly ISession session; public ReferenceBinder(ISession session) { this.session = session; } public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var idName = CreateSubPropertyName(bindingContext.ModelName, "ID"); ValueProviderResult result = bindingContext.ValueProvider.GetValue(idName); int value; return (int.TryParse(result.AttemptedValue, out value)) ? this.session.Load<T>(value) : null; } } </code></pre> In your example you would do something like this in Global.asax: <pre><code>ModelBinders.Binders.Add(typeof(Position), new ReferenceBinder<Position>(<pass your current session implementation or use DI/IoC>)); </code></pre> (I'm using Castle Windsor to create the actual binder and populate session in my implementation) Assuming your domain model is: <pre><code> public class Player { public virtual Position Position {get;set;} } public class Position { public virtual int ID {get;private set;} } </code></pre> And your postback looks like this: <pre><code>"Position.ID" = <id from dropdown> </code></pre> EDIT: You should probably use a DTO approach with dedicated view models. I've learned this later on. <a href="http://stevesmithblog.com/blog/binding-in-asp-net-mvc/" rel="nofollow">Have a look here for a quick start</a>.

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.
