Property Value

Type Description
TreeDerivationMode

A TreeDerivationMode enumeration value that specifies the tree derivation mode.

Available values:

Name Description
Selfreference

Builds a tree from a self-referential data structure. To learn more, see Bind to Self-Referential Data Structure.

ChildNodesSelector

You should manually write code to specify where a data object’s child items come from by creating a selector class. To learn more, see Bind to Hierarchical Data Structure.

HierarchicalDataTemplate

Builds a tree using Hierarchical Data Templates. To learn more, see Hierarchical Data Templates.

Remarks

In data bound mode, the TreeListView can display information in a tree from either a self-referential (flat) or hierarchical data structure. For each type of a data structure, it provides the corresponding tree derivation mode(s), specified via the TreeDerivationMode property.

If the TreeDerivationMode property is set to TreeDerivationMode.HierarchicalDataTemplate, optimized mode is automatically disabled.
