Log:
* ListViewItem.cs: Collections of selected and checked items are now
dynamically rebuilt. Whenever an item is (un)checked or (de)selected
we mark the collection "dirty".
* ListView.cs: Marked collections readonly. Modified UpdateSelection
to only clear SelectedItems when a new item is selected and MultiSelect
is enabled. CheckedItems and SelectedItems now subscribe to Changed
event of ListViewItemCollection, and mark its list dirty whenever
that event is fire. This allows us to return selected/checked items
in the same order as they are in the Items collection. This matches
the MS behavior.
* ListViewCollectionsTest.cs: Added tests for bug #79415.
* ListViewTest.cs: Enabled test for bug #79416.
