Hi Joost,
Thanks for using Syncfusion product.
As now we can disable hours in Day, Week, WorkWeek and TimeLine view by setting NonAccessibleBlocks in the schedule control. Please refer the below UG documentation for more details about setting NonAccessibleBlock in the schedule control.
We don’t have any support to disable dates in the month view. In SfSchedule WinRT platform we are having support to disable dates in the month view by setting MonthBlockOutDates in the schedule control. Please refer the below UG documentation for setting MonthBlockOutDates in the WinRT schedule control.
We suspect that your requirement is similar to MonthBlockOutDates in Winrt schedule control. Could you please revert us back, if this is your requirement? so that we could log feature request and proceed further or else could you please provide more information about your requirement? so that we could analyze on your requirement further and provide you the possible solution.
Regards
