TDBComboBox represents a data-aware combo box control.
Use TDBComboBox to allow users to change the value of a field on the current record in a dataset either by selecting an item from a list or by typing in the edit box part of the control. The selected item or entered text becomes the new value of the field if the database combo box's ReadOnly property is false. The combo box can be customized to enable or disable typing in the edit region of the control, to display the list as a drop down or as a permanently displayed list, to sort the items in the list, and so on.
