In this case, the synchronization between the CollectionViewSource CurrentItem and RadListBox SelectedItem fails. The CurrentItem of the collection will reset the SelectedItem property of the RadListBox.

The ScrollIntoView method of RadListBox doesn't work when the VirtualizingPanel.ScrollUnit property is set to Pixel and the ItemsPanel of the control is VirtualizingWrapPanel.

If you create a class implementing ListBoxDragDropBehavior and override the CoerceDraggedItems method, the return value is not utilized. 

Introduce property to control the visibility of the drop visual when the drop is not allowed. For example, when the AllowReorder property is False and the user tries to reorder rows.

Available in LIB version 2016.1.321, it will be also available in the 2016 Q2 Release.

Currently only the "Up" and "Down" keyboard keys perform navigation. It would be useful if the "Left" and "Right"keys are also used for navigation.

The navigation should be as follows:
- Left goes left
- Right goes right
- Up goes up
- Down does down

 

The LinearDropVisual element is not displayed below the last item in a drag-drop scenario when ScrollViewer.CanContentScroll is set to False.

SelectionChanging event could be added for preventing selection in code, just like SelectionChanging event in RadGridView and PreviewSelectionChanged in RadTreeView

Available in R3 2017 Official Release Version.

 Extremely bad selection performance with large numbers of items (above 10K).

A workaround is to use the SelectedItem of the control and get the value of the needed property of the item.

Available in the R1 2017 SP1 Release.

Currently, when a RadListBoxItem container is selected it will be highlighted and scrolled to, which causes the ScrollViewer to "auto-scroll". We could add option to enable/disable this scrolling behavior.

Available with the R3 2016 SP1 release. 

Currently , RadListBox does not take into account the value of the attached property KeyboardNavigation.DirectionalNavigation.
Users need to set DirectionalNavigation to Continue  / Cycle / Contained.
Default value of this property is Continue, but RadListBox acts like Contained and disregards the attached property.

For example if there are the following items: "Item", "Item 2", "Item 3"
when the RadListBox has the focus typing "Item 2" does not highlight the corresponding item in the ListBiox control.

Available in LIB version 2016.2.525, it will be also available in the 2016 R2 SP1 release.
