The Scheduler in the Lite version has two relevant properties:
- BusinessBeginsHour
- BusinessEndsHour
They will allow you to define the business hour start and end but the actual effect is a different background color of the time cells (BackColor vs. NonBusinessBackColor).
The same applies to the Scheduler in the Pro version.
Only the Dynamic Scheduler from the Pro version has the ability to actually hide the non-business hours (use ShowNonBusiness="false").
