    <p>I am trying to find the most elegant way I can use to bind to a combobox on a Windows Form without using code behind. On the form I have a combobox with two binding sources. One is bound to a Controller, which contains a List of Countries and when called populates this list. The other binding source is bound to the other binding source bound to the controller and I have set the data members as the collection of 'Countries'. I am using EF5 to fetch my data in the controller. However, from what I have done I cannot get the combobox populated when I run my application. Please assist on what I am missing in terms of databind? Please find my code below:</p> <pre><code> static class Program { /// &lt;summary&gt; /// The main entry point for the application. /// &lt;/summary&gt; [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); IUnityContainer container = new UnityContainer(); Modules.RegisterModules(container); var controller = container.Resolve&lt;IController&gt;(); Application.Run(new TestForm(controller)); } } internal static class Modules { public static void RegisterModules(IUnityContainer container) { container.RegisterType&lt;IController, GeoController&gt;(); container.RegisterType&lt;IModelContainer, GeoModelContainer&gt;(); } } public class GeoController : IController, INotifyPropertyChanged { private List&lt;Continent&gt; _continents; private List&lt;Country&gt; _countries; private List&lt;City&gt; _cities; IModelContainer Container { get; set; } public GeoController(IModelContainer container) { Container = container; Countries = Container.Countries.ToList(); } #region Properties public List&lt;Country&gt; Countries { get { return _countries; } set { _countries = value; OnPropertyChanged(); } } #endregion public event PropertyChangedEventHandler PropertyChanged; [NotifyPropertyChangedInvocator] protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null) { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName)); } } public interface IController { List&lt;Country&gt; Countries { get; set; } } public partial class TestForm : Form { IController Controller { get; set; } public TestForm(IController controller) { InitializeComponent(); Controller = controller; } } </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.
