I just spotted on the blog that the TileList now offers to "arrange the tiles into groups with dedicated headers"
Do you happen to have an example on how to do this?
You can organize the Tiles into groups using Tile's property - Group. Moreover, you are able to specify the look and feel of a group by using RadTileList's property GroupTemplate. Please find attached a sample project that shows you this functionality.
I hope this information helps. Please let me know if I can assist you any further.
