VB.NET

Public Property HoldRootValue As Boolean

Property Value

Type	Description
Boolean	true, if the nodes whose parent node is absent in the data source are displayed as root; otherwise, false. The default value is false.

Remarks

This property affects what nodes are displayed in a List View represented by the TreeListEditor, when filtering the List View’s ListView.CollectionSource. If the HoldRootValue property is set to true, then after a List View has been filtered so that some parent nodes are now missing, their first-level child nodes will be displayed as root. If the HoldRootValue property is set to false, the child nodes will not be displayed.
