Hello everyone,

Indeed, I agree that this is an unpleasant issue and I bumped the priority in our internal backlog. Please use the following workaround while we fix it:

The OnEdit event of the Scheduler provides the start and edit time of the clicked slot. Set those (or different values) to the edit item:

    private void SchedulerOnEditHandler(SchedulerEditEventArgs args)
    {
        var editedItem = (SchedulerAppointment)args.Item;
        if (args.IsNew)
        {
            editedItem.Start = args.Start;
            editedItem.End = args.End;
        }
    }

Regards,
Dimo
