Iconos de los componentes agrupados en la página Data Controls
Esta página incluye componentes especialzados para gestión de bases de datos:
| DBGrid | Data-aware custom grid that enables viewing and editing data in a tabular form similar to a spreadsheet. Makes extensive use of TField properties (set in the Fields editor) to determine a column's visibility, display format, ordering, and so on. |
| DBNavigator | Data-aware navigation buttons that move a table's current record pointer forward or backward. The navigator can also place a table in Insert, Edit, or Browse state, post new or modified records, and retrieve updated data to refresh the display. |
| DBText | Data-aware label that displays a field value in the current record. |
| DBEdit | Data-aware edit box that displays or edits a field in the current record. |
| DBMemo | Data-aware memo box that displays or edits BLOB text in the current record. |
| DBImage | Data-aware image box that displays, cuts, or pastes bitmapped BLOB images to and from the current record. |
| DBListBox | Data-aware list box that displays a scrolling list of values from a column in a table. |
| DBComboBox | Data-aware combo box that displays or edits a scrolling list of values from a column in a table. |
| DBCheckBox | Data-aware check box that displays or edits a Boolean data field from the current record. |
| DBRadioGroup | Data-aware group of radio buttons that display or set column values. |
| DBLookupListBox | DBLookupListBox is a data-aware list box that derives its list of display items from either a Lookup field defined for a dataset or a secondary data source, data field, and key. In either case, a user is presented with a restricted list of choices from which to set a valid field value. When a user selects a list item, the corresponding field value is changed in the underlying dataset. To specify list box items using a lookup field, the dataset to which you link the control must already define a lookup field. |
| DBLookupComboBox | DBLookupComboBox is a data-aware combo box that derives its drop-down list of display items from either a lookup field defined for a dataset or a secondary data source, data field, and key. In either case, a user is presented with a restricted list of choices from which to set a valid field value. When a user selects a list item, the corresponding field value is changed in the underlying dataset. To specify combo box list items using a lookup field, the dataset to which you link the control must already define a lookup field. |
| DBRichEdit | A multiline edit control that can display and edit a rich text memo field in a dataset. |
| DBCtrlGrid | A DBCtrlGrid control displays multiple fields in multiple records in a tabular grid format. Each cell in the grid displays multiple fields from a single record. |
| DBChart | Place the component on a form and right-click it to display the third-party developer's Help topics. |
