Hi Gayathri,
Greetings from Syncfusion Support.
You can get the appointments of selected date using getEvents public method. When passing the start and end time, the appointments for the selected date will be retrieved. Please refer to the following sample.
onCellClick(args) {
var currentDateEvent = this.scheduleObj.getEvents(
args.startTime,
args.endTime
);
}
Please try the solution and get back to us if you need any further assistance.
Regards,
Nevitha
