Can you please give a little bit more details about what you want to achieve? You cannot completely remove the tile headers since they contain visual parts that are required by the control. Even if you were able to completely remove the header, then the user would not be able to maximize/minimize the tiles, or reorder them with mouse dragging. To disable the double-click on the item headers, you can set RadTileView's TileStateChangeTrigger property to "None". To disable the resizing animations, set the IsItemsAnimationEnabled property to "false".
