Overview

The WinUI TreeView control is a hierarchical list view that represents hierarchical data in a tree-like structure with expand and collapse node options. The control provides an optimized reuse strategy, smooth scrolling experience, and virtualization. It makes illustrating an office hierarchy, organizational structure, or nested relationships in an application easy. The control’s performance is enhanced with features like data binding, unbound node population, template selector, drag and drop, selection with different selection modes, complete UI customization, and commands for MVVM.


Data binding

Use both ItemsSource binding and unbound node population. Easily customize the TreeView control as a navigation control by populating nodes in the unbound mode. In addition, all the properties and commands of the WinUI TreeView can be used in the MVVM pattern.

Load on demand

Check boxes

Add check boxes to each tree node and check or clear the corresponding node. It provides built-in support for recursive checking between parent and child nodes. Recursive checking is the process where the check/uncheck state of a child node is decided based on the parent when users interact with parent node and vice versa.
