Thanks for the kind words !
You may subscribe to the SelectionChanged event in order to react to changes of the currently selected tile.
In case this does not work for you , you may subscribe to the mouse events from within the content of the tile you define in XAML.
Regarding the Nasdaq value - you are the first to notice the typo. I am afraid I can not manipulate the Nasdaq points, so please have some Telerik points instead :) .
