Description

Use TSRVDBListBox to add a list box to a document that permits users to change the value of a field on the current record to one of a fixed set of choices.

If the application doesn't require the data-aware capabilities of TSRVDBListBox, use a list box (TSRVListBox) instead to conserve system resources.
