As a workaround, the ScrollingSettingsBehavior.ScrollStep attached property of the RadListBox control can be set to a value equal to that of the Height of the RadListBoxItems.

Available in R3 2017 Official Release Version.

Can be reproduced when RadListBox is placed inside a Grid, a StackPanel with horizontal orientation or a WrapPanel.

The "auto scroll into the view on selection" functionality does not to work as expected if the ItemsPanel is changed and a selection was previously done.

When the ItemsSource of the control is changed to a new collection the old selected items are cached and if a collection containing the old selected items source is set as ItemsSource the cached items are restored.

Make it possible to disabled this functionality per control.

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.

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:
http://blogs.telerik.com/xamlteam/posts/13-01-14/extending-the-functionality-of-radcontrols-with-attached-properties

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 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.
