Namespace: Autodesk.Revit.DB.EventsAssembly: RevitAPI (in RevitAPI.dll) Version: 26.2.0.0 (26.2.0.0)
Syntax
C#
public bool Cancellable { get; }Property Value
Boolean
Remarks
If Cancellable returns true, event delegates may cancel the command that
was announced by the event. To do so, a delegate may call the Cancel() method if it is available.
Typically, single-events and post-events (e.g. DocumentPrinted) are not cancellable,
while most pre-events (e.g. DocumentPrinting) are cancellable, except for special
conditions and situations, such as when the Revit application is being closed
or if an event is raised during another event.
