Т.е., в самом DataWindow события не программируются вообще? Только, когда DataWindow помещен на форму?

1. Програмируются. Наследуетесь от DataWindow и в нем програмируете события. А потом его и на форму можна.

2. Посмотрите название кнопки и дайте ее поиск в проекте. Если в event buttonclicked() есть строка
choose case dwo.name
case "<name button>"
...
тогда вам повезет ее найти
3. В Painter перейдите на закладку event и найдите buttonclicked()
4. а вот из Helpa

Usage

The ButtonClicked event executes code after the action assigned to the button has occurred.
This event is fired only if you have not selected Suppress Event Processing for the button.
If Suppress Event Processing is on, only the Clicked event and the action assigned to the button are executed when the button is clicked.
If Suppress Event Processing is off, the Clicked event and the ButtonClicked event are fired. If the return code of the ButtonClicking event is 0, the action assigned to the button is executed and the ButtonClicked event is fired. If the return code of the ButtonClicking event is 1, neither the action nor the ButtonClicked event are executed.

Do not use a message box in the Clicked event If you call the MessageBox function in the Clicked event, the action assigned to the button is executed, but the ButtonClicking and ButtonClicked events are not executed.
Web DataWindow ButtonClicked fires only for buttons with the UserDefined action. Other buttons cause the page to be reloaded from the server.
