There are no such built-in delays but you can consider using the RadTile's client-side API to reset/modify timers when needed: http://www.telerik.com/help/aspnet-ajax/tilelist-client-side-tile-api.html
. You can get a reference to a given tile by its name, for example, and reset/change its timers as required (the methods you can use include set_peekShowInterval(value), set_peekCloseDelay(value), showPeekTemplate(), startPeekShowInterval()).
If you manage to create such functionality and post it in the code-library section
we will gladly award your efforts with Telerik points.
