Where is the bubbleevent using SB1DE

Hi

I am using the SB1DE and want to trap when the add button is pressed on the delivery note screen. I will then ask the user a question and if they respond no I do not want the delivery note to be added.

Using vb6 and the ui api you could just set bubbleevent = false and the operation would be cancelled.

I can't seem to work out how to do this with the SB1DE.

Any ideas please ?

Thanks

Regards Andy
