Examples

Tip

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

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.
