CollectionViewNavigator

The CollectionViewNavigator control allows users to navigate the items or pages in CollectionView components.

To use it, set the navigator's cv property to the CollectionView instance it should control.

To navigate by page, set the byPage property to true. To navigate by item, set it to false.

You can customize the display of the current item/page by setting the navigator's headerFormat property.
