Hi Assadi ,
Inorder to display the time in milliseconds in DateTimePickerAdv, we can use the custom format hh:mm:ss.ff. However, this doesn''t seem to work and I could notice the same behavior with .NET DateTimePicker also.
As a workaround, I would suggest you to create a custom DateTime TextBox using ButtonEdit, CalendarPopUp and MonthCalendarAdv as illustrated in the sample attached.
Please let me know if this helps you.
Regards,
Anu
