Thanks for your reply David.

Nice try :), but it's already .F.

Col3 contain one container comming from a class.
This container suppose to showing or not(visible=.T. or .F.) the field contain the child info.

Ex:
i just wanna see 1textbox in a container if this record just have 1 child.

It's look like foxpro initialise the container only for the first record and show it for all. ?!?

any other idea?
