    <p>I am using a HierarchicalDataTemplate to bind my classes to a TreeView with checkboxes. I have the code working fine and everything is displayed fine, but I'd like to be able to get a list of children of an item in my treeview.</p> <p>When a checkbox is clicked, I want to be able to select the parent nodes and child nodes. If I had access to the TreeViewItem that is supposed to wrap the checkbox then I could easily do this, but the Parent property of the Checkbox is null... I can only seem to gain access to my classes that are mapped in the HierarchicalDataTemplate.</p> <pre><code>&lt;TreeView Margin="12" Name="trv1" SelectedItemChanged="trv1_SelectedItemChanged"&gt; &lt;TreeView.Resources&gt; &lt;HierarchicalDataTemplate DataType="{x:Type src:Location}" ItemsSource="{Binding Path=Sublocations}"&gt; &lt;CheckBox Content="{Binding Name}" Tag="{Binding}" IsChecked="{Binding IsChecked}" Click="checkBox_Click"/&gt; &lt;/HierarchicalDataTemplate&gt; &lt;HierarchicalDataTemplate DataType="{x:Type src:Sublocation}" ItemsSource="{Binding Path=Children}"&gt; &lt;CheckBox Content="{Binding Name}" Tag="{Binding}" IsChecked="{Binding IsChecked}" Click="checkBox_Click"/&gt; &lt;/HierarchicalDataTemplate&gt; &lt;DataTemplate DataType="{x:Type src:Child}"&gt; &lt;CheckBox Content="{Binding Name}" Tag="{Binding}" IsChecked="{Binding IsChecked}" Click="checkBox_Click"/&gt; &lt;/DataTemplate&gt; &lt;/TreeView.Resources&gt; &lt;TreeView.ItemContainerStyle&gt; &lt;Style TargetType="TreeViewItem"&gt; &lt;Setter Property="IsSelected" Value="{Binding IsChecked}"/&gt; &lt;/Style&gt; &lt;/TreeView.ItemContainerStyle&gt; &lt;/TreeView&gt; </code></pre>
