Body
As requested, here are my ViewModels. ViewModelBase is the standard one created by studio. MainVieModel has got just enough to in it to create the test menus I was using to experiment with. Basically I am working towards creating a Parent/Child menu classes I can use with a series of apps we sell to a broad collection of clients. I hope to make it where each customer can have a customizable collection of menus based upon their needs and which moudles they've purchased licenses for. <pre><code>public abstract class ViewModelBase : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; protected void OnPropertyChanged(string propertyName) { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) { handler(this, new PropertyChangedEventArgs(propertyName)); } } } </code></pre> public class MainViewModel : ViewModelBase { <pre><code> public MainViewModel() { MakeMenus(); } private void MakeMenus() { // Makes some dummy menus to test with. Menus = new ObservableCollection<MyMenuItem>(); ParentMenu parent; ChildMenu child; parent = new ParentMenu("First Level"); Menus.Add(parent); child = new ChildMenu(parent, "second level"); parent.ChildMenuItems.Add(child); ChildMenu child2 = new ChildMenu(child, "third level"); child2.MenuCommand = new DelegateCommand(CommandTest, CommandCanExecute_First); child.ChildMenuItems.Add(child2); child = new ChildMenu(parent, "second level 2"); parent.ChildMenuItems.Add(child); child2 = new ChildMenu(child, "third level 2"); child2.MenuCommand = new DelegateCommand(CommandTest, CommandCanExecute_Second); child.ChildMenuItems.Add(child2); parent = new ParentMenu("Another First"); parent.ChildMenuItems.Add(new ChildMenu(parent, "Another Second")); Menus.Add(parent); OnPropertyChanged("Menus"); } private bool ExecuteToggle { get; set; } private void CommandTest() { ExecuteToggle = !ExecuteToggle; } public ObservableCollection<MyMenuItem> Menus { get; private set;} public bool CommandCanExecute_First() { return ExecuteToggle; } public bool CommandCanExecute_Second() { return !ExecuteToggle; } } </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.
