The Menu event is not an event managed by the ColumnView control, but by 
its Control parent class. This is the reason why the Item property is 
not set during the Menu event handler. The Menu event is raised even if 
you don't click on an item.

Normally, the Click event will be raised before the Menu event, and so 
you can store the key of the ColumnView.Item property during the Click 
event handler (which is a ColumnView event) to use it later during the 
Menu event handler.

The Item property *is* set during a Click event handler. What are you 
talking about with "generate a columnview click event"?
