onbeforeupdate event | beforeupdate event
Occurs on a databound object before it updates the data in the data source object.
If the contents of a databound object are modified and the databound object loses the active state, then the associated data in the data source object is updated. In that case, the onbeforeupdate event is fired before and the onafterupdate event is fired after the update process. If an error occurs while updating, the onerrorupdate event is fired instead of the onafterupdate event.
These events occur on the databound object. If you need an event that occurs on the data source object when its data has changed, use the oncellchange event.For further details about data source objects, see the page for the recordset object.
How to register:
