Thank you for contacting Syncfusion support.
Yes, it is possible to open the Edit window in single appointment click instead of double click and for the same we have prepared the below sample which can be viewed from the below link.
<Code>
appointmentWindowOpen: "appWindowOpen",
appointmentClick: "OnAppointmentClick",
function OnAppointmentClick(args) {
args.cancel = true;
if (!args.appointment.Recurrence)
this._showAppointmentDetails(args.appointment.Guid, true);
else {
if (ej.isNullOrUndefined(this._recurEditWindow)) this._renderRecurEditWindow();
this._parentId = args.appointment.ParentId;
this._recurEditWindow.ejDialog("open");
this._recurEditWindow.focus();
this._deleteBeforeOpen();
}
}
function appWindowOpen(args) {
if (!ej.isNullOrUndefined(args.appointment))
$("#Schedule1AppointmentAddEditWindow_title").find('.e-title').html("Edit Appointment");
else
$("#Schedule1AppointmentAddEditWindow_title").find('.e-title').html("Create Appointment");
}
</Code>
Note: Above sample is made in JS platform for your reference.
