The IsSynchronizedWithCurrentItem property works only in the Single SelectionMode. With the other two modes, the synchronization works partially - only initially. Changes in the control's selection doesn't update the CurrentItem of the associated collection view.

In this particular case, the RadListBox is placed inside RadBusyIndicator. When we set the DragDropManager.UseAdornerLayer static property to true, drop functionality is restricted. A possible workaround here is to avoid using RadListBox as a content of RadBusyIndicator

Release R3 2020 SP1

In this particular scenario, the RadListBox is placed inside DataTemplate and its ItemsSource property is bound to CollectionViewSource.View. Now when we try to bind the SelectedItem property, the binding fails. The reason behind this is that when the RadListBox is loading, the CurrentItem of the CollectionViewSource is set to the SelectedItem property after the binding kicks in. Which will break the binding. To workaround this we can set the CurrentItem to Null.

MyCollectionViewSource.View.MoveCurrentToPosition(-1);

If you set the SelectedIndex after an item is added in the Items or ItemsSource of RadListBox, the selection doesn't work. 

To work this around, use the SelectedItem property instead of SelectedIndex.

Release LIB 2019.2.708 (7/8/2019)
If you host a RadMaskedTextInput control in the listbox items and focus the input, then pressing Space will send the focus to the corresponding RadListBoxItem instead of adding an empty space character into the text input.

To work this around, create a custom RadListBox control and override its HandleKeyboardInput method.
public class CustomListBox : RadListBox
{
    protected override bool HandleKeyboardInput(Key key)
    {
        if (key == Key.Space)
        {
            return false;
        }
        return base.HandleKeyboardInput(key);
    }
}
