Hi Sauro,
Thank you for using Syncfusion products.
We have checked the reported query at our end and suspect that your requirement is to show only To-Do events of the day as shown in below image(AgendaView). As now, Schedule control does not have support for ScheduleView or agenda view to show the events only of a day.
If we misunderstood your requirement, we request you to explain your scenario with screenshots or video.
Thanks & Regards,
Balamurugan Thirumalaikumar
