My solution is based on this example:
http://blogs.msdn.com/b/lightswitch/archive/2012/12/19/enhancing-lightswitch-controls-with-jquery-mobile-michael-zlatkovsky.aspx
further steps:
- set the initial variables (max,..) under "_created"
- enable the slider (so the user can not change the value)
- add some logic to increment the value of the local property which is bound to the slider, when the user steps further in his progress
Best regards
