Table field linked to a data file (Table file)
Not available with this kind of connection
A Table control linked to a data file is a field whose columns are linked to fields in a data file or query. The data file and the query are considered to be the data source. Each Table control column can be: - Bound to an item of the data source.
- Linked to a field in a data file linked to the data source.
- Calculated: If the column is not linked to a field in a data file, it is a calculated column. calculated column. For calculated columns, the content of the column is recalculated each time a row is displayed.
Each row in the Table control corresponds to a record of the data source. A Table control linked to a data file allows you to: - View the content of a data file (or query) with one record per row and select a record (view the entire file or a selection of records selected according to a filter).
View the content of bound records (for example, view the order lines associated with an order displayed in the Table control). - Delete a record by deleting a row from the Table control.
- Modify a record by modifying the content of a row found in the Table control.
- Add a record by entering a row in the Table control.
 Automatically refresh the data modified from another computer.
The number of records that can be viewed is unlimited, but only the visible rows in the Table control are loaded in memory. Notes - Table control fields linked to a data file are mainly used to display data. To enter data, use the Edit controls.
- The row selected in the Table control corresponds to the current record in the data file. If the position is set to a different row in the Table control, the position in the data file also changes to the corresponding record.
