    <p>I am trying to successfully TwoWay bind an ObservableCollection to TextBoxes in a DataTemplate. I can get the data to display properly, but I am unable to change the list data through the UI. I have a Model class named 'model' which contains an ObservableCollection named 'List'. The class implements the INotifyPropertyChanged interface. Here is the xaml for the shell. The DataContext for Window1's grid is set to "theGrid.DataContext=model" </p> <pre><code>&lt;Window x:Class="BindThat.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:BindThat" Title="Window1" Height="300" Width="300"&gt; &lt;StackPanel x:Name="theGrid"&gt; &lt;GroupBox BorderBrush="LightGreen"&gt; &lt;GroupBox.Header&gt; &lt;TextBlock Text="Group" /&gt; &lt;/GroupBox.Header&gt; &lt;ItemsControl ItemsSource="{Binding Path=List}"&gt; &lt;ItemsControl.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;TextBox Text="{Binding Path=., Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" /&gt; &lt;/DataTemplate&gt; &lt;/ItemsControl.ItemTemplate&gt; &lt;/ItemsControl&gt; &lt;/GroupBox&gt; &lt;/StackPanel&gt; </code></pre> <p></p> <p>This is the code for the Model class:</p> <pre><code>class Model : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; private void NotifyPropertyChanged(string name) { if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(name)); } private ObservableCollection&lt;string&gt; _list = new ObservableCollection&lt;string&gt;(); public ObservableCollection&lt;string&gt; List { get { return _list; } set { _list = value; NotifyPropertyChanged("List"); } } public Model() { List.Add("why"); List.Add("not"); List.Add("these?"); } } </code></pre> <p>Could anyone advise if I am going about this the correct way?</p>

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.
