Let me get straight to your question. As you (manually) remove the RadTileViewItems
from your business collection you can add the "fade out" animation just before you delete the item. In order to this you can use a DispatcherTimer
to decrease the opacity of the item to 0 and then you can delete it. Please take a look at the attached project and let me know if it works for you.
