Key features
Hierarchical Navigation: RadTreeView significantly improves the navigation and performance of your application where navigation over hierarchical structure is required.
Expand/Collapse API: RadTreeView introduces several methods which can be used to programmatically control the state of its items.
Commands Support: RadTreeView strictly follows the MVVM best practices and provides an intuitive and easy-to-use set of APIs that allow different aspects of the RadTreeView control’s behavior to be handled and/or completely overridden. RadTreeView exposes a Commands collection that allows you to register custom commands with each control’s instance.
CheckBox Support: Telerik RadTreeView provides check boxes buttons displayed next to each item. The RadTreeView allows the user to check/uncheck the nodes and to perform various tasks with the collection of checked nodes. The Tri-State CheckBox mode of RadTreeView allows for RadTreeViewItems' CheckBoxes to have an additional, third state - Indeterminate.
Data Binding: Simply setting the collection of custom business objects as an ItemsSource in combination with a "HierarchyAdapter" class is enough to visualize the hierarchically-structured source.
Load on Demand: Load On Demand feature allows you to delay the population of RadTreeView and load subitems only when they’re requested, thus improving the overall performance of your app.
UI Virtualization: The user interface uses virtualization for displaying the required elements, meaning that they are created only when needed and only for the currently visible cells.
Theming Support: RadTreeView comes with built-in theming support that allows you to easily build slick interfaces with the look-and-feel of a predefined theme
