I'm looking to save the display index of the tiles in a TileList in our database, so users can each have their own order of the tiles.
It appears you can't databind DisplayIndex, so I assume I have to update the viewmodels from the code behind. I'm fine with this, but if there is a way to databind the displayindex so my view models are automatically updated, let me know.
I'd prefer to not add a "Save" button. I'd like to have it automatically save whenever a tile is rearranged. However I can't find an event to handle when the tiles are rearranged. And since the display index is not databound, and the order of the itemssource is not updated by the TileList, I also have no events in the viewmodels that tell me the order was changed either.
