Property Value

Type Description

true if the operation raising the event should be canceled; otherwise, false.


The NavBarGroupExpandedChangingEventArgs object is passed to events that fire before specific initiated actions are completed. The Cancel property of this object enables you to cancel the action which is about to be performed.

For example, this property is useful when you handle the ExplorerBarView.GroupExpandedChanging event. Set this property to true to cancel the expanding or collapsing of the processed group. This can be used if you want to prohibit group expanding/collapsing with respect to specific conditions.
