    Description

    UpdateAction implements action update support. It should never be necessary to call UpdateAction from program code, as it is called automatically whenever a target control needs to update an action. This method must be overridden in case any specific action must be taken when the action must be updated. The implementation in TDatalink checks if the action handles the datasource, and then calls Action.UpdateTarget, passing it the datasource. If so, it returns True.
