    <p>I'm pretty new to WPF so excuse me for any dumb question...</p> <p>I have a ListView with three columns that is binded to a XmlDataProvider source like the following:</p> <pre><code> &lt;XmlDataProvider x:Key="Properties" XPath="/Info"&gt; &lt;x:XData&gt; &lt;Info xmlns=""&gt; &lt;Property Name="Text" Value=""/&gt; &lt;!--0--&gt; &lt;Property Name="Tooltip" Value=""/&gt; &lt;!--1--&gt; &lt;Property Name="Enable" Value=""/&gt; &lt;!--2--&gt; &lt;Property Name="Visible" Value=""/&gt; &lt;!--3--&gt; &lt;Property Name="Focus" Value=""/&gt; &lt;!--4--&gt; &lt;Property Name="Selected" Value=""/&gt; &lt;!--5--&gt; &lt;Property Name="Count" Value=""/&gt; &lt;!--6--&gt; &lt;Property Name="Item" Value=""/&gt; &lt;!--7--&gt; &lt;Property Name="SelectedText" Value=""/&gt; &lt;!--8--&gt; &lt;Property Name="SelectedIndex" Value=""/&gt; &lt;!--9--&gt; &lt;Property Name="Complete" Value=""/&gt; &lt;!--10--&gt; &lt;/Info&gt; &lt;/x:XData&gt; &lt;/XmlDataProvider&gt; </code></pre> <p>The ListView is defined as following:</p> <pre><code> &lt;ListView Name="lstProperties" Margin="55 0 0 0" Style="{DynamicResource TsListView}" Grid.Row="2" Grid.RowSpan="7" Grid.ColumnSpan="4" ItemsSource="{Binding Source={StaticResource Properties}, XPath=Property}" ItemContainerStyle="{DynamicResource TsListViewItem}" ScrollViewer.HorizontalScrollBarVisibility="Hidden" SelectionMode="Single" IsEnabled="False" SelectionChanged="propertySelected" &gt; &lt;ListView.View&gt; &lt;GridView AllowsColumnReorder="False"&gt; &lt;GridViewColumn CellTemplate="{StaticResource FirstCell}" Width="25" /&gt; &lt;GridViewColumn Header="Property" Width="80"&gt; &lt;GridViewColumn.CellTemplate&gt; &lt;DataTemplate&gt; &lt;Label Style="{DynamicResource TsLabel}" Height="25" Width="115" Content="{Binding XPath=@Name}" /&gt; &lt;/DataTemplate&gt; &lt;/GridViewColumn.CellTemplate&gt; &lt;/GridViewColumn&gt; &lt;GridViewColumn Header="Value" Width="130"&gt; &lt;GridViewColumn.CellTemplate&gt; &lt;DataTemplate&gt; &lt;TextBox Style="{DynamicResource TsHelperTextBox}" Height="20" Width="115" Text="{Binding XPath=@Value}" IsEnabled="{Binding ElementName=rbTypeAssert, Path=IsChecked}" GotFocus="gridTextBox_GotFocus" /&gt; &lt;/DataTemplate&gt; &lt;/GridViewColumn.CellTemplate&gt; &lt;/GridViewColumn&gt; &lt;/GridView&gt; &lt;/ListView.View&gt; &lt;/ListView&gt; </code></pre> <p>What I want to do now is fairly simple: I just want to enable/disable some of the ListViewItems. The only way I found to get ListViewItems is through the following method:</p> <pre><code>lstProperties.ItemContainerGenerator.ContainerFromIndex(index) </code></pre> <p>This makes me a little uncomfortable. I should be getting the Items through the name property of Property. Is there anyway to do this? I'm also having problems when I try to do this right after the window is initialized. I get a NullReferenceException when trying to disable one of these ListViewItems. It seems that right after the window is rendered the binding is not done yet.</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).
