The RadTileView went through a major refactoring during Q1 2011 and that's why there are a couple of changes. Two of them are related yo your problems:
- in Q3 2010 the default MinimizedColumnWidth was 250, but now it is Auto and that's why the items are not placed as you'd have expected. If you set the MinimizedColumnWidth property of the TileView to 250 everything should be ok.
- the animations in the RadTileView are no longer Double animations and that's why they look a little bit different. At the moment you can have a lot more RadTileViewItems (with the Virtualization you can have 500+) and the performance with Double Animations was not good and that's why we changed them.
