If these controls are bound to fields, then they don't update until you leave them - and the record doesn't update until you leave the record. In that case, maybe requery the form, but that will put you back onto the first record if this is a datasheet or continuous form. If that's a bother, you'd get the bookmark property of the current record, requery, then make the current record equal to the bookmark value.
If your table is open and you choose a value and then moving off the field or record and activate the table window again, chances are you need to refresh the table from the ribbon. Switching to the table window often does not refresh the view, so you might think the new value isn't in the table, but it is.
The more we hear silence, the more we begin to think about our value in this universe.
