Body
I've come up with a solution that works but is clearly a work around. I've removed the validation attribute and created a custom model binder instead which manually adds an error to the <code>ModelState</code> dictionary for the property <code>Group.Name</code>. <pre><code>public class SearchBinder : DefaultModelBinder { protected override void BindProperty(ControllerContext controllerContext, ModelBindingContext bindingContext, PropertyDescriptor propertyDescriptor) { if (propertyDescriptor.Name == "Group" && bindingContext.ValueProvider.GetValue("Group.Name") != null && bindingContext.ValueProvider.GetValue("Group.Name").AttemptedValue == "") { ModelState modelState = new ModelState { Value = bindingContext.ValueProvider.GetValue("Group.Name") }; modelState.Errors.Add("Please create a new group or choose an existing one."); bindingContext.ModelState.Add("Group.Name", modelState); } base.BindProperty(controllerContext, bindingContext, propertyDescriptor); } } // Register custom model binders in Application_Start() ModelBinders.Binders.Add(typeof(SearchViewModel), new SearchBinder()); </code></pre> With <code>ModelState["Group.Name"]</code> now having an error entry, the CSS class is being rendered in the markup. I would much prefer if there was a way to do this with idiomatic validation in MVC though. <h2>Solved!</h2> Found a proper way to do this. I was specifying the wrong property name in the self validating class, so the key that was being added to the <code>ModelState</code> dictionary was <code>Group.Group.Name</code>. All I had to do was change the returned <code>ValidationResult</code>. <pre><code>yield return new ValidationResult("Please create a new group or select an existing one.", new[] { "Name" }); </code></pre>

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.
