MapperExtensionKernelMapperCommand Method

Fired when a mapper command has been invoked. MapperCommands can be added to a mapper programmatically by adding a MapperCommand(IMapper, EAPCommandEventArgs) to Commands, typically during the MapperBeforeLayout(IMapper, EAPEventArgs) event. They can also be specified in meta-data via a NavTarget with TargetType of Command on a menu Navigator.
