When the ItemsPanel of the RadListBox is RadWrapPanel and the user press Down/Up key the RadListBox selects always the next/previous item instead of the corresponding item on the next/previous row.

The exception is caused when running the project in debug mode. 

The SelectionMode must be Multiple.

Use case that hits the described issue:

When binding another control to a shared SelectedItem property from a ViewModel causes the Item to not be updated correctly to the ListBox and the anther control.

When the ItemsPanel is set to VirtualizingStackPanel which Orientation is set to Horizontal, selecting an item moves it to the rightmost position.

Available in LIB version 2016.3.1017, it will be also available in the 2016 R3 SP1 release. 

Implement a public event that is triggered when selection has been made by the user interaction. This even could be useful when a custom logic should be handled when a user selection has been made in the control but not when the change has come from the ViewModel.

When drag and drop and reorder are allowed dropping an item after the last item in the control  requires the drop to be exactly after the last item and there is very little space between the item and the outer border of the ListBox

This happens when using VirtualQueryableCollectionView as the ItemsSource.

The SelectionMode must be Multiple.

I would like to see the visual feedback (red frame about the control and the error message inside) when the binded property has an error message in a error collection.

When the control is initially Collapsed setting the SelectedIndex does not update the SelectedItem property of the control and vice versa.

If a dragged item is not over an existing item of the ListBox control the drop cue is not displayed. By default it should be rendered after the last item in the ListBox control.

Available in the 2014 Q2 Release.

Add IsFocused dependency property to the RadListBoxItem of the control.

Implement IsSynchronizedWithCurrentItem property in order to disconnect the connection with CollectionViewSource.

RadListBoxItems looks selected when BusyIndicator is made busy

ListBoxItem is going to the last position when dragged and dropped in to the SCrollViewer.
