  1. POHow do you reproduce the text displayed in a TreeViewItem while using a ControlTemplate?
    text
    copied!<p>I am attempting to modify a TreeView to display the TreeViewItem values above and below their child items, such that:</p> <pre><code>foo |bar ||baz |biz </code></pre> <p>would become</p> <pre><code>foo |bar ||baz | baz |bar |biz biz foo </code></pre> <p>A trimmed representation of the current control template is provided below, provided with no guarantee that this snippet compiles:</p> <pre><code>&lt;ControlTemplate TargetType="{x:Type TreeViewItem}"&gt; &lt;Grid&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition MinWidth="19" Width="Auto"/&gt; &lt;ColumnDefinition Width="Auto"/&gt; &lt;ColumnDefinition Width="*"/&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="Auto"/&gt; &lt;RowDefinition/&gt; &lt;RowDefinition Height="Auto"/&gt; &lt;/Grid.RowDefinitions&gt; &lt;ToggleButton x:Name="Expander" IsChecked="{Binding Path=IsExpanded, RelativeSource={RelativeSource TemplatedParent}}" ClickMode="Press"/&gt; &lt;Border Name="Bd" Grid.Column="1" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Padding="{TemplateBinding Padding}"&gt; &lt;ContentPresenter x:Name="PART_Header" ContentSource="Header" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"/&gt; &lt;/Border&gt; &lt;ItemsPresenter x:Name="ItemsHost" Grid.Row="1" Grid.Column="1" Grid.ColumnSpan="2"/&gt; &lt;TextBlock Text="Some Binding Goes Here" Grid.Row="2" Grid.Column="1" Grid.ColumnSpan="2"/&gt; &lt;/Grid&gt; &lt;/ControlTemplate&gt; </code></pre> <p>The repeated entries would not have children, it would just be the display value. Thus far I can modify the TreeView ContainerStyle using a ControlTemplate to insert a TextBlock at the appropriate place in the visual tree. What data binding should be used in order to fetch the appropriate display value?</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
