    <p>I have a <code>ListView</code> declared like this : </p> <pre><code>&lt;ListView x:Name="lvRSU" Margin="3" Background="#84978F" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ItemsSource="{Binding rsus}"&gt; &lt;ListView.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;Grid Grid.Row="0" VerticalAlignment="Center"&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="90"/&gt; &lt;ColumnDefinition Width="240"/&gt; &lt;ColumnDefinition Width="40"/&gt; &lt;ColumnDefinition Width="40"/&gt; &lt;ColumnDefinition Width="110"/&gt; &lt;ColumnDefinition Width="100"/&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Label Content="{Binding Name}" ContentStringFormat="{}{0} Path" VerticalAlignment="Center" /&gt; &lt;TextBox Grid.Column="1" HorizontalAlignment="Stretch" VerticalAlignment="Center" Margin="2,0,0,0"/&gt; &lt;Button Grid.Column="2" HorizontalAlignment="Center" VerticalAlignment="Center" Width="22" Height="22" MaxHeight="22" MaxWidth="22" ToolTip="Open .rsu file" SnapsToDevicePixels="True"&gt; &lt;Image Source="Resources/Folder16.png" Stretch="Uniform" &gt;&lt;/Image&gt; &lt;/Button&gt; &lt;CheckBox Grid.Column="3" Content="En" VerticalAlignment="Center"/&gt; &lt;ComboBox ItemsSource="{Binding sensorTypes}" Grid.Column="4" HorizontalAlignment="Stretch" VerticalAlignment="Center"&gt; &lt;ComboBox.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text="{Binding}"/&gt; &lt;/DataTemplate&gt; &lt;/ComboBox.ItemTemplate&gt; &lt;/ComboBox&gt; &lt;CheckBox Grid.Column="5" Content="{Binding Name}" ContentStringFormat="Inv {0}" VerticalAlignment="Center" Margin="2,1,1,1"/&gt; &lt;/Grid&gt; &lt;/DataTemplate&gt; &lt;/ListView.ItemTemplate&gt; &lt;/ListView&gt; </code></pre> <p>and in the .cs file i have the following connection : </p> <pre><code>public ReadOnlyObservableCollection&lt;string&gt; _sensorTypes = new ReadOnlyObservableCollection&lt;string&gt;(new ObservableCollection&lt;string&gt;() { "1", "2"}); public ReadOnlyObservableCollection&lt;string&gt; sensorTypes { get { return _sensorTypes; } } </code></pre> <p>also i set the <code>DataContext</code> for my ListView : </p> <pre><code>lvRSU.DataContext = this; </code></pre> <p>But i can't get the items in my combobox at all. Maybe there is a problem because it's inside the grid ?</p> <p>It's ok i got it now.</p> <pre><code> ItemsSource="{Binding RelativeSource={RelativeSource AncestorType=ListView},Path=DataContext.sensorTypes}" </code></pre> <p>This one made the difference. I am going to the DataContext of the ListView which contains at some point my combobox, and i set the Path from there. Thanks.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
