Available in LIB version 2015.3.1019, it will be also available in the 2015 Q3 SP1. Fix provided by the new IsScrollIntoViewEnabled property.

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.

When RadListBox is in a ScrollViewer and its own ScrollViewer is removed, it uses the external ScrollViewer for calculating DropVisualPlaceHolder position.

I have a custom ListBox that inherits from RadListBox control which uses a VirtualizingWrapPanel as its ItemTemplate.
I am trying to use BringIndexIntoViewPublic method to bring a certain ítem that is still not created into view, but it does not work. I also try to use ScrollIntoView of the RadListBox, and is also not working.

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

Select item,  populate the control with new items and do multiple selection with shift key. The selected items are with one more.

Add AlternationCount, AlternateBackground and ItemLoaded event just like the RadGridView ones.

Using an attached property to populate the SelectedItems of the control initially selects only the first item.

A sample project (ListBoxSelectedItems - Example) of the used approach can be found in this blog post:

Currently the scrolling is not behaving as expected.
