This is a bad answer, but I'm including it here to contribute to understanding of the question. It would seem that the answer would be "YES" you must implement INotifyPropertyChanged in your model for controls to get notified of their change (thus allow controls to update when they are changed). But if the above is true why can a TextBox databound to a entity cause changes in other controls. Try it! For example you can bind a TextBox's Text property to the SelectedItem of a DataGrid (which is bound to a ObservableCollection from a .Local) with UpdateSourceTrigger=PropertyChanged. Now run and select a row in the DataGrid and edit the TextBox and the text in the DataGrid row will update realtime! How does the text box force that change in the DataGrid!?!?! Here is the binding code of the above example: <pre><code><TextBox Text="{Binding Path=SelectedItem.Name, UpdateSourceTrigger=PropertyChanged}" /> </code></pre> This works with a TextBox not just on the same View, but even if the entity is gathered from SelectedItem and passed in to a second view which then has a TextBox that binds to the entity. (Manages to update the first window's DataGrid realtime!) This is super cool! Now I wish I could find a way to in code SelectedItem.Name = "New Name", because no matter what I try that will not update the DataGrid. (I can't refresh the DataGrid directly because I'm using MVVM and have no access to it) Note: I'm using EF4.1 with DBContext & POCO entities (ie. simple classes that do not implement any interfaces)

1. COBinding a text box to the SelectedItem in datagrid works because SelectedItem is a dependency property: http://msdn.microsoft.com/en-us/library/ms752914.aspx Dependency properties handle their own automatic updating and do not need to implement INotifyPropertyChange. They are a UI specific kind of property

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.
