We are Creating One Functionality where user can create recurrence Appointment.

for that we had create one Table in Database ,Id(increment),StartDate,EndDate,Subject,RecurrenceRule,RecurrenceId

For Example,

If User first create one Appointment with the following settings


In Database We Find Dates Between Date and Store each date Separate Appointment.

Now when We load data and pass to scheduler control Datasource 

            Id: 1,
            Subject: 'Appointment1',
            StartTime: new Date(2019, 09, 21, 9, 30),
            EndTime: new Date(2019, 09, 22, 11, 30),
            IsAllDay: false,
            RoomId: 1,
            RecurrenceRule: "FREQ=DAILY;INTERVAL=1;UNTIL=20191005T080703Z;",
            RecurrenceStartDate: new Date(2019, 8, 2, 9, 30),
            RecurrenceEndDate: new Date(2019, 8, 2, 9, 30)
            Id: 2,
            Subject: 'Appintment2',
            StartTime: new Date(2019, 8, 8, 9, 30),
            EndTime: new Date(2019, 8, 8, 11, 30),
            IsAllDay: false,
            RoomId: 1,
            RecurrenceRule: "FREQ=DAILY;INTERVAL=1;UNTIL=20191005T080703Z;",


In above Scenario i Can see two time Appointment for Date the reason is Based on Rule Calendar also Render Appointment based on Rule
How can we default rendering false based on Recurrence Rule ,can we render event as per Datasource?

Hi Mayank, 
Syncfusion greetings. 
We can perform CRUD operations using DataManager and kindly refer the below links. 
Note: Run the service sample before JS to fetch and load the events in UI. 
By default DB contain only the parent recurrence event and it is handled internally. Please find the below details.  
Recurrence Appointment Db structure for JS2.   
Adding recurrence appointment to db:    
When single occurrence is edited its date will be added to parent event’s RecurrenceException field in ISO format and the edited occurrence’s RecurrenceID field is updated with parent event id value like below.  
We strongly recommend not to manually update the events.
