Hi Chevron,
Greetings from Syncfusion Support.
We could prevent the default popup opening by setting args.cancel= true within popupOpen event and get the date in args.data. We have prepared sample for your reference which can be available in the following link.
onPopupOpen(args: PopupOpenEventArgs): void {
if (args.type === "Editor") {
let srtTime = (args.data as any).StartTime; // To get the start time value
let endTime = (args.data as any).EndTime; // To get the end time value
console.log("StartTime: " + srtTime + " and endTime: " + endTime); // To display the time in console
// args.cancel = true; // To disable the default editor window
}
}
Kindly try out the above sample and let us know if need any further assistance.
Regards,
Nevitha
