| Run Time Interaction > Searching and Field Completion > Searching in TDBCombo |
Incremental searching is always "on" for TDBCombo controls, which search for an entry matching all characters entered, and perform the search incrementally as characters are typed. This behavior is almost identical to that of a TDBList control with its MatchEntry property set to 2 - Extended except that the search argument is not cleared when the user presses Backspace or hesitates for a few seconds. If the ComboStyle property is set to 2 - Dropdown, you can use the MatchEntryTimeout property to specify the timeout value. After the user hesitates for the specified amount of time, the combo text entry box will clear and the next characters entered will begin a new search.
