    <p>I'm trying to do this as MVVM as possible:<br /> My Model (<b>InterestTypeEntity</b>) implements INotifyPropertyChanged.<br /> My ViewModel (<b>InterestTypeAllViewModel</b>) has an ObservableCollection that binds to a DataGrid. When changes are made to it, it sends those changes (add/remove) to the Database.</p> <p>the problem is, I want to also be able to update the database when the properties of the objects within the collection change. I'm not sure how to do that? Here's my code so far...</p> <p>XAML:</p> <pre><code>&lt;DataGrid Name="TestGrid" Grid.Row="3" Grid.ColumnSpan="2" AutoGenerateColumns="False" ItemsSource="{Binding IntTypes}" SelectedItem="{Binding CurrentIntType}"&gt; &lt;DataGrid.Columns&gt; &lt;DataGridTextColumn Header="Interest ID" Binding="{Binding IntType}" /&gt; &lt;DataGridTextColumn Header="Interested Parties Description" Binding="{Binding Description}" MaxWidth="500" /&gt; &lt;/DataGrid.Columns&gt; &lt;/DataGrid&gt; </code></pre> <p>ViewModel Code:</p> <pre><code>public ObservableCollection&lt;InterestTypeEntity&gt; IntTypes { get { return DataRepository.InterestTypeEntities; } } public InterestTypeEntity CurrentIntType { get; set; } public Int16 IntType { get { return CurrentIntType.IntType; } set { if (value != CurrentIntType.IntType) { CurrentIntType.IntType = value; OnPropertyChanged("IntType"); } } } public String Description { get { return CurrentIntType.Description; } set { if (value != CurrentIntType.Description) { CurrentIntType.Description = value; OnPropertyChanged("Description"); } } } </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.
