WPF Tree List - Bind to Self-Referential Data Structure

This example shows how to create a self-referential data structure and display it in the TreeListView.

To display this tree structure, your data source should include the following fields of the same data type:

• Key Field - This field should contain unique values used to identify nodes. Assign its name to the TreeListView.KeyFieldName property.
• Parent Field - This field should contain values that indicate parent nodes. Assign its name to the TreeListView.ParentFieldName property.

Set the TreeListView.TreeDerivationMode property to Selfreference to enable the self-referential mode.
