I have a variety of TileLists that I can't quite make work the way I
need.
When I drag a row from a DataGrid and drop it on the TileList, I want
to take the data from 3 of the 4 columns in the DataGrid, and drop them
into the TileList. Currently it just shows {object Object}.
I need to determine programatically if the TileList has anything in it.
When something is dropped in the TileList, I need to prevent additional
drops and I need to change the Alpha to 1.
Additionally, if the item is removed from the TileList, I need set
dropEnabled back to true and the Alpha to 0.
