You may want to take a look at the OnConfirmDelete (I assume setting Confirmed to false will cancel the delete) and OnCustomDelete (or possibly OnGetCanModify) events.

Subject: [IBO] Deleting records, or not

Hi everyone!

Is there any way to "cancel" a delete command in a TIB_Query?

Let me explain: when user delete a record in a TIB_Grid i would like to
cancel this operation and replace the usual behaviour for my own set of
commands.

Maybe in OnBeforeDelete event? But, how i cancel the delete operation?

Thanks!!

Emerson
