Changing the min / max value of the progressbar isn't possible. For now, we have to destroy the progressbar and recreate a new one using the new min / max values.
Hi Simon,
You can use the following approach to achieve your requirement:
var progressBar = $("#progressbar").getKendoProgressBar()
progressBar.setOptions({min: 10})
