Cancellable Property

Indicates whether an event may be cancelled by an event delegate.

Namespace: Autodesk.Revit.DB.Events
Assembly: RevitAPI (in RevitAPI.dll) Version: 2015.0.0.0 (2015.0.0.0)
Since: 2011

Syntax

C# 
public bool Cancellable { get; }
Visual Basic 
Public ReadOnly Property Cancellable As Boolean
	Get
Visual C++ 
public:
property bool Cancellable {
	bool get ();
}

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.
