T:Microsoft.UI.Xaml.Controls.TreeView |
winrt class |
Represents a hierarchical list with expanding and collapsing nodes that contain nested items.
This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).
You can modify the default Style and ControlTemplate to give the control a unique appearance. For information about modifying a control's style and template, see XAML styles. XAML also includes resources that you can use to modify the colors of a control in different visual states without modifying the control template. Modifying these resources is preferred to setting properties such as Background and Foreground. For more info, see the Light-weight styling section of the XAML styles article.
The resources for this control are listed in the ThemeDictionaries section of the TreeView_themeresources.xaml file on GitHub. The ResourceKey value for each StaticResource references a brush and color in the Common_themeresources_any.xaml file.
