Incremental searching is always enabled for C1Combo controls; with incremental searching C1Combo controls search for an entry matching all characters entered, performing the search incrementally as characters are typed. This behavior is almost identical to that of a C1List control with its MatchEntry property set to 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 DropdownCombo or SimpleCombo, 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.
