Hi Ewald,

I am afraid that virtual scrolling is currently not supported when adding or removing items from the DataSource. Virtual scrolling uses ranges instead of pages to determine which items to be displayed and adding a new item or deleting an existing one results in miscalculated ranges, which in turn breaks the scrolling.
