EnabledResolved Property

(Read-only) Returns true only if this UltraTreeNode, all of its ancestor nodes, and the UltraTree control to which it belongs, is Enabled.
Syntax
'Declaration
 
Public ReadOnly Property EnabledResolved As Boolean
public bool EnabledResolved {get;}
Remarks

An UltraTreeNode is treated as disabled if the node's Enabled property, or the Enabled property of any of its ancestor nodes or its UltraTree control, is set to false.

A disabled node cannot be edited, selected or activated; nor can its Expanded state be changed via the user interface.

Example
The following sample code illustrates some of the information exposed by a mode.
