Tip

For more info, design guidance, and code examples, see TreeView.

Open the WinUI 3 Gallery app and see the TreeView in action.

The WinUI 3 Gallery app includes interactive examples of most WinUI 3 controls, features, and functionality. Get the app from the Microsoft Store or get the source code on GitHub.

Constructors

TreeViewNode()

Initializes a new instance of the TreeViewNode class.

Properties

Children	Gets the collection of nodes that are children of the current node.
Content	Gets or sets the data content for the current node.
ContentProperty	Identifies the Content dependency property.
Depth	Gets a value that indicates how far the current node is from the root node of the tree.
DepthProperty	Identifies the Depth dependency property.
Dispatcher	Always returns `null` in a Windows App SDK app. Use DispatcherQueue instead. (Inherited from DependencyObject)
DispatcherQueue	Gets the `DispatcherQueue` that this object is associated with. The `DispatcherQueue` represents a facility that can access the `DependencyObject` on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
HasChildren	Gets a value that indicates whether the current node has child items.
HasChildrenProperty	Identifies the HasChildren dependency property.
HasUnrealizedChildren	Gets or sets a value that indicates whether the current node has child items that haven't been shown.
IsExpanded	Gets or sets a value that indicates whether the current tree view node is expanded.
IsExpandedProperty	Identifies the IsExpanded dependency property.
Parent	Gets or sets the node that is the parent of the current node.

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)
