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.

Improve the performance when selecting a large number of items, using Ctrl + A, for example.

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.

 

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

It would be great to have ScrollPositionIndicatorTemplate for RadListBox, similar to RadGridView (see RadGridView's implementation here http://docs.telerik.com/devtools/wpf/controls/radgridview/features/scrolling).

Introduce a feature where a scroll position indicator is displayed when the deferred scrolling is enabled (ScrollViewer.IsDeferredScrollingEnabled=True). The scroll indicator is a small tooltip displayed next to the scrollbar and displaying information about the potential item that should be displayed at the top of the viewport. 

This is the same as in RadGridView's ScrollPositionIndicator. You can check this in the following help article: (http://docs.telerik.com/devtools/wpf/controls/radgridview/features/scrolling#scrollpositionindicator). See also the attached video.

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

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

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.

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.

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

Currently the scrolling is not behaving as expected.
