Description
TDBEdit represents a single-line edit control that can display and edit a field in a dataset.
Use TDBEdit to enable users to edit a database field. TDBEdit uses the Text property to represent the contents of the field.
TDBEdit permits only a single line of text. If the field may contain lengthy data that would require multiple lines, consider using a TDBMemo object.
If the application does not require the data-aware capabilities of TDBEdit, use an edit control (TEdit) or a masked edit control (TMaskEdit) instead, to conserve system resources.
To provide a mask that restricts input and controls the display format of the data, use mask-related properties of TField and descendants. Such properties include: EditMask (TField), DisplayFormat (TDateTimeField), and DisplayFormat (TNumericField). Which property you should use depends on the field's type and the TField descendant that corresponds to that type.
