Addendum: Visibility/Collapsed of individual tiles does not have anything to do with recreating the problem as I first thought. Is seem that while the control is initializing it is ignoring tile positioning from code behind, once it is fully initialized everything works as expected. My problem is I don't know when it is done 'initializing'. I have animation off so annimationcompleted never fires. TilePositionChanged does fire, once for each tile on load, so this code does work, but it is only a slight improvement over the timer, in that I need to know the order the tiles load and move tiles only after they have been initially positioned.
