I would use the selectedIndices instead
and call removeItemAt. removeTreeNode is used for Trees.

- Removing Item from tileList
Hello,
I have another newbie question
I am trying to remove an item from a tileList control
after dropping the item onto a Canvas control. I know something is not
right, but where am I going wrong.
Many thanks,
David T.
