Default events
WEBDEV - Server codeWEBDEV - Browser codePHP WEBDEV manages the following events by default (order of appearance in the code editor):
EventRuntime condition
Initializing (Server code)Executed when the page is opened.
Special case: Table control based on a data file filled automatically:
When this code is run, the Table control is not filled yet. To force the control to be filled in this code, use:
You can also filter records with HFilter.
End of initialization (Server code)Code only for automatically populated Table controls based on a data file:
Executed after the Table control has been populated. This code is used to select an element in the Table control, to add or modify an element.
Row selection (Server code)Code run when the user selects a row in the Table control.
Row selection (Browser code)Table control in "Server + AJAX" mode
Run when the user selects a row (without input).
Table control in "Browser" mode
Run when the user selects a row (without input)
Row display (Server code)Run when a new row must be displayed in the Table control: redisplaying the Table control, scrolling or moving in the Table control, etc.
Used to manage the calculated columns.
Row display (Browser code)Table control in "Browser" mode only
Run when a new row must be displayed in the Table control: redisplaying the Table control, scrolling or moving in the Table control, etc.
Table click (Browser code)Run when the Web user selects a row.
Exit from a row (Server code)Table control in "Server + AJAX" mode only
Run when moving from one row or control to another (TAB key, selecting another control with the mouse, etc.)
Filter records (Server code)Code only for automatically populated Table controls based on a data file:
Run just before displaying a row. This event filters the records displayed in the Table control. This event is detailed at the end of this page.
Optional events
Several optional events are supported. To add an optional event:
  1. Select the desired control.
  2. Display the code window of this control (F2 key).
  3. Click the link "Add other events to xxx" at the bottom of the window code, after the last event.
  4. All the optional events available for the control are displayed.
  5. Check the optional event to add and validate.
    Remark: You can select several optional events.
  6. The selected optional event is automatically added to the events managed by the control.
To disable an optional event, simply perform the same operations to display the list of optional events. Then simply uncheck the optional events to delete.
Remark: If the disabled code contains WLanguage code, this code is automatically deleted.
You can manage, for example:
  • the mouse hover over the control,
  • left mouse button down, up, double click,
  • right mouse button down, up, double click,
  • mouse wheel, etc.
Remark: The optional events differ according to the environment (WINDEV, WEBDEV, WINDEV Mobile) and the development platform.
Filter records (Table based on a data file only)
WEBDEV - Server codePHP The "Filter records" event is executed after a row of the Table control is displayed. Therefore, it is run:
  • when initializing the Table control.
  • whenever a row is displayed in the Table control.
This event filters the records displayed in the Table control.
To implement a filter, the "Filter records" event must return a value:
  • True to specify that the record matches to the filter and that it must be displayed.
  • False to specify that the record does not match the filter and that it must not be displayed.
  • Cancel to stop reading the data source of the table (very rare case).
Example:
// -- Filter the records
// Displays the customers who placed orders exceeding 3000 Euros
IF Orders.TotalIOT >=3000 THEN
RETURN True
ELSE
RESULT False
END
In this code, the data used affects the record currently read by the Table control. This data comes from the data file or query linked to the Table control.
Remark: In WINDEV and WINDEV Mobile, the event "Recording the records" is an optional event. In WEBDEV, this event is proposed by default.
