Overview
A browsing table control is a control whose columns are linked to items found in a data file or in a query (data source). Each Table control column can be:
  • Linked to an item of the data source
  • Linked to an item of a file linked to the data source
  • Calculated: If the column is not linked to a file item, it is a calculated column. For the calculated columns, the content of the column is re-calculated whenever a row is displayed, it is not stored.
Each row of the Table control corresponds to a record of the data source.

A browsing table control is used 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).
  • Delete a record by deleting a row from the Table control.
  • Modify a record by modifying the content of a Table control row.
  • Add a record by entering a row in the Table control.
The number of records that can be viewed is unlimited, only the visible rows of the Table control are loaded in memory.

Browsing table with direct access and Browsing table loaded in memory
WinDev

Types of browsing Table controls

Two types of browsing Table controls are available:
  • The browsing Table controls based on the file in direct access. These are the "standard" browsing Table controls.
  • The browsing Table controls based on a file loaded in memory. Only a specific number of file records (specified in the editor) is loaded in memory. These browsing Table controls are mainly used to perform sorts and searches on any column.
See Comparison between the features of Table controls for more details.

Notes
  • Browsing Table controls are used mainly to view data. To enter data, use the edit controls.
  • The row selected in the Table control corresponds to the current record in the data file. When changing row in the Table control, the current record in the data file is automatically modified.
