None of the Suneido data entry Controllers that I know of have a built-in automatic refresh.
To do this you’d need a timer in your Controller (BookControl does this). On the timer you could call Save and then Refresh/Reload the data in your Controller. One problem with this is you wouldn’t want to do this if the user was in the middle of an entry. There would likely be other issues to deal with that I haven’t thought of.
