    <p>I have a custom class that I would like to bind a WPF TreeView that has three tiers. Each tier needs to be bound like this:</p> <pre><code> Monitor --&gt; LCD --&gt; Samsung 1445 LCD --&gt; CRT --&gt; Sony 125 CRT </code></pre> <p>Here is the example code:</p> <pre><code>public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); SystemInventory sysInventory = new SystemInventory(); //Possibly do something like this. _myTreeView.DataContext = sysInventory.DeviceGroupInstances; } public class SystemInventory { public ObservableCollection&lt;DeviceGroup&gt; DeviceGroupInstances { get; set; } public SystemInventory() { DeviceGroupInstances = new ObservableCollection&lt;DeviceGroup&gt;(); DeviceGroupInstances.Add(new DeviceGroup("Monitor")); } } public class DeviceGroup { public string DeviceGroupName { get; set; } public ObservableCollection&lt;DeviceType&gt; DeviceTypeInstances { get; set; } public DeviceGroup(string deviceGroupName) { DeviceTypeInstances = new ObservableCollection&lt;DeviceType&gt;(); DeviceGroupName = deviceGroupName; if (deviceGroupName == "Monitor") { DeviceTypeInstances.Add(new DeviceType("LCD")); DeviceTypeInstances.Add(new DeviceType("CRT")); } } } public class DeviceType { public string DeviceTypeName { get; set; } public ObservableCollection&lt;DeviceInstance&gt; DeviceInstances { get; set; } public DeviceType(string deviceGroupName) { DeviceInstances = new ObservableCollection&lt;DeviceInstance&gt;(); DeviceTypeName = deviceGroupName; if (deviceGroupName == "Monitor") { DeviceInstances.Add(new DeviceInstance("Samsung 1445 LCD")); } else { DeviceInstances.Add(new DeviceInstance("Sony 125 CRT")); } } } public class DeviceInstance { public string DeviceInstanceName { get; set; } public DeviceInstance(string instanceName) { DeviceInstanceName = instanceName; } } } </code></pre>

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).
