ListBox ScrollIntoView when using CollectionViewSource with GroupDescriptions (i.e. IsGrouping == True)

Question

Short version

I would like to scroll the ListBox item into view when the selection is changed.

Long version

Answer 1

1. The out of the box VirtualizingStackPanel does not support virtualizing grouped collection views. When a grouped collection is rendered in an ItemsControl, each group as a whole is an item as opposed to each item in the collection which results in "jerky" scrolling to each group header and not each item.

2. You'll probably need to roll your own VirtualizingStackPanel or ItemContainerGenerator in order to keep track of the containers displayed in a group. It sounds ridiculous, but the default virtualization with grouping in WPF is lacking to say the least.
