Two parameters are passed to the handler:

* **sender** - the scheduler client object;

* **eventArgs** with three properties:

  * **get_command()** - the navigation command that is being processed.

  * **get_selectedDate()** - the date that RadScheduler will navigate to.

  * **set_cancel()** - set to true to cancel the operation.

This event can be cancelled.
