Revit API 2012 Event handler for Cancel and Finish buttons

Question

I need events to catch the finish and cancel buttons in Revit when creating a model group, or a Floor for example. The image below shows the buttons. Are there events for these actions?

Answer 1

我不确定，但是我想至少完成按钮会引发Document_Changed事件，也许您可​​以获得事务的名称来缩小您真正想要的操作。
