DayPilot » Knowledge Base » How to define Calendar business and non-business days

The default rules for determining business days in DayPilot Calendar are as follows:

• All weekend time slots (Saturday and Sunday) are marked as non-business.
• On workdays, only the slots between BusinessBeginsHour and BusinessEndsHour are marked as business.

If you need to define custom rules you have two options:

• Change BusinessBeginsHour and BusinessEndsHour. This will affect all workdays the same way.
• Handle BeforeCellRender event and override the status of individual time slots using e.IsBusiness. This will allow you to have different working hours each days and include/exclude individual days.

Example:

  protected void DayPilotCalendar1_BeforeCellRender(object sender, BeforeCellRenderEventArgs e)
  {
        // Turn Saturday and Sunday into business days
        if ((e.Start.DayOfWeek == DayOfWeek.Saturday || e.Start.DayOfWeek == DayOfWeek.Sunday)
            || (e.Start.Hour >= DayPilotCalendar1.BusinessBeginsHour && e.Start.Hour < DayPilotCalendar1.BusinessEndsHour))
        {
            e.IsBusiness = true;
        }
  }
