TileList is missing the "Value" property, now the same effect is obtained via HiddenFiled on ContentTemplateTile. This is in contrast with a lot of others Telrik Controls.
I'm asking Telrik to implement this functionality

RadTileList offers an OnClick event: http://docs.telerik.com/devtools/aspnet-ajax/controls/tilelist/server-side-programming/events/ontileclick
Tiles have a Name property that is an arbitrary string and you can use it like a Value if you like.
