Your ticket is posted in RadButton forums, and that`s why my sample code is with RadButtn control.
RadFormDecorator does not have content template. That`s why we have RadButton control, which put buttons on a higher level of customization (you could use icons, content templates etc.). You should use RadButton in the way showed in my previous mail. Actually I do not see what would help you RadFormDecorator in that case as it just decorates asp buttons, while at the same time you need one more element inside the button for the balloons containing the numbers.
Of course, you could wrap an asp decorated button into a span element, and inside to put another span, that will be decorated as a balloon and then to be placed inside the decorated button, but this is a whole new much more complicated approach that is out of the scope of our controls support.
