>Judging from your answer, you don't seem to have used AllowAddNew before. If that is so, may I know how you add a new line to the grid in a master-detail form if the user doesn't like the idea of clicking a new button or remember a special key like {CTRL-INS} kind of thing? Can you give me some tips?

Tai, you're right, I don't use the AllowAddNew. At least in 5.0 there were some problems, so I developed my own technique. When my users down-arrow on the last record, I do an insert with the primary and foreign surrogate keys and any other information (date added, user) that I want to add automatically. If they complete this record, they can continue to add. If not, then when they down-arrow again they are asked if they want the blank record. Any record added but not edited by the user (I use GetFldState) is deleted automatically.
