Thanks for the second answer.
About the first :
I have to check if a record exist, I usually launch a message which tells the user that the record was not found, now I was asked to leave the focus on the same control or in some case to set the focus to the preceding column.
I put the code in the lost focus event, something like this :
do case
case somecondition
this.setfocus()
case othercondition
this.parent.parent.columns(ncol).txt.setfocus()
endcase

this approach does not work properly, maybe i interact in a wrong way with my classes but i'm very mixed up
