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, a 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, a template selector, drag and drop, selection with different selection modes, complete UI customization, and commands for MVVM.
Use both ItemsSource binding and unbound node population. Easily customize the TreeView control to be a navigation control by populating nodes in the unbound mode. All the properties and commands of the WinUI TreeView can be used in the MVVM pattern.
The WinUI TreeView allows you to load huge amounts of data dynamically improving the control’s performance. Make use of a loading indicator while loading on demand.
Customize an entire tree’s nodes by hosting any image or custom view using a template. Customize each node through dynamic selection of the UI using a data template selector.
Use built-in support for selection with single, single-deselect, multiple, extended, and none modes. Background colors can be applied to selected items. You can also select using keyboard navigation.
The WinUI TreeView provides animation support when expanding or collapsing the TreeView nodes.
Add checkboxes to each tree node and check or clear the corresponding node. The control provides built-in support for recursive checking between parent and child nodes. Recursive checking is the process where the checked or unchecked state of a child node is decided based on the parent when users interact with parent node and vice versa.
Show a context flyout when a node is long-pressed or right-clicked. Use the built-in commands to handle the context flyout, edit a node, and delete one or more selected nodes.
Use a customizable expander UI, including size customization, for creating an elegant look and feel.
Specify the required indentation space for child nodes in the WinUI TreeView control.
Show a line between tree nodes. Decide whether lines should be drawn between tree nodes at the root of the WinUI TreeView control.
Easily get started with the WinUI Treeview using a few simple lines of C# code as demonstrated below. Also explore our WinUI Treeview Example that shows you how to configure the Treeview.
