Tree List

  • 3 minutes to read

The WPF Tree List (TreeListControl) is a data-aware control designed to display and edit hierarchical data. The TreeListControl allows users to manage data (sort, filter, and so on).


The Tree List is available as a stand-alone control or as one of the Data Grid Views.

Get Started

Bind to Data

Refer to the following topic for more information: Bind to Data.

Display Hierarchical Data

The TreeListControl can display data in a tree from a self-referential (flat) or hierarchical data structure.

Self-Referential Data
Build a tree if objects in a data source contain Key and Parent fields.
Child Nodes Path
Set a path to the children field. Use this technique only when child and parent fields have the same object type.
Child Nodes Selector
Create a selector that returns node children. You can use this technique for different object types.
Asynchronous Child Nodes Selector
Fetch child nodes in a background thread to keep the TreeListView responsive to user actions.
Hierarchical Data Templates
Create a template for different data types.
Unbound Mode
Create a tree without a data source.

Refer to the following help topic for more information: Display Hierarchical Data.
