CollectionView Currency

The CollectionView has a currentItem property that identifies the item that is currently active.

This property is used by controls that support binding to lists and selection (including FlexGrid, FlexChart, ListBox, ComboBox, etc).

The example below implements a simple master/detail screen. Select a country from the ComboBox to change the current item. This raises the currentChanged event which is used to update the elements that show details of the current item.

Country
Downloads	17,587
Sales	$796.26
Expenses	$3,890.39
