    <p>So, I have a <code>listview</code> with different <code>datatemplates</code> as seen here:</p> <pre><code>&lt;ListView Panel.ZIndex="0" x:Name="FilterList" Margin="10,0" Grid.Row="2" Grid.ColumnSpan="3" Background="White" ItemTemplateSelector="{StaticResource ReportFilterTemplateSelector}" ItemsSource="{Binding reportParameters, Mode=TwoWay}" ScrollViewer.CanContentScroll="False"&gt; </code></pre> <p>One of my sample <code>datatemplates</code> can be seen below. Everything shows up great. My problem, is that for this (and other) <code>datatemplates</code>, I can have multiple instances of the same one. In this particular instance, the <code>treeview</code> <code>itemssource</code> is bound to <code>DataContext.OfficeListText</code> to populate all the elements.</p> <pre><code> &lt;DataTemplate x:Key="office"&gt; &lt;Grid MinHeight="35" MaxHeight="250"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition/&gt; &lt;/Grid.RowDefinitions&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="100"/&gt; &lt;ColumnDefinition/&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;TextBlock Text="{Binding rpName}" VerticalAlignment="Center" Grid.Row="0" Grid.Column="0" /&gt; &lt;Expander HorizontalAlignment="Stretch" Grid.Row="0" Grid.Column="1" Header="{Binding Path=DataContext.OfficeListText, RelativeSource= {RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}" VerticalAlignment="Top" ExpandDirection="Down"&gt; &lt;TreeView Tag="{Binding rpParameter}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ItemsSource="{Binding Path=DataContext.OfficeList, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Mode=TwoWay}" ItemTemplate="{StaticResource CheckBoxItemTemplate}" ItemContainerStyle="{StaticResource TreeViewItemStyle}"/&gt; &lt;/Expander&gt; &lt;/Grid&gt; &lt;/DataTemplate&gt; </code></pre> <p>The main problem with this is one, for instance, if I select an office in say the first <code>treeview</code>, the 2nd <code>treeview</code> shows the same. Essentially I want them to have the same itemssource initially but have separate instances. Since they are generated dynamically that is where I'm getting stuck. Any help would be appreciated. </p> <p>I'm not sure what other code would be necessary, since I'm sure most of it will be irreverent based on what I'll need to do to make this work, but if you would like more I will gladly provide. Thanks!</p>

    1. COCan you elaborate on "if I select an office in say the first treeview, the 2nd treeview shows the same"?

    2. COUmm, the datatemplate is used on bound data... If you want different data sources, you should bind to separate instances... i believe you should be able to create an instance in resources of the control and bind to that, though i don't really get the whole picture from your question, so you might want to improve it...

    3. CO@foosburger Say two of the "office" datatemplates are displayed, what happens on one affects the other. I'm assuming this is because the treeview itself is bound to the same `DataContext.OfficeList` instance.

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.
