I need the ability to have a Preview or a Detail View added to the ListView. I need to know when an item is scrolled off of the top of the list view. I want to place a preview or a details view just above the list view. I need an Scroll Event to take action and populate the preview. Scenario: The UI will have a listview of Reports. We want to display the report titles in the list view. We want to show a preview of the report. The Author, Publish Date, a description, etc. When the user scrolls the listview, we want to update this preview or detail panel.
