Selecting one item per group is not supported out of the box by the RadTileList control. You could try to achieve this behavior using custom code. I have searched for a possible solution and I think I manage to found one. I have created a sample project and attached it to this reply. In a few words, I have subscribed to the SelectionChanged
of the control and I am checking the currently selected item. If there is already selected item for this group I am removing it from the SelectedItems collection. Keep in mind that, adding/removing items from the SelectedItems collection will trigger the SelectionChanged event again.
