Hi Sonam,
Greetings from Syncfusion Support.
We suspect that dataSource for Scheduler is assigned before the Scheduler is rendered which could cause the reported problem. We suggest you to assign the dataSource to the scheduler in componentDidMount as in the following code.
componentDidMount() {
//assign your dataSource to events variable
this.scheduleObj.eventSettings.dataSource = events;
}
Please check whether the above solution works at your end, else please revert us back with the scheduler code snippets to check further on this.
Regards,
Nevitha
