change behaviour of all editable fields in a control

Question

If you edit a field in oracle Forms the record in the database will be locked, so nobody can change ore edit this field.
Now I want to implement this behaviour in .net.
I want all controls in which I can edit something (Text, Check, list box ore dbtables...) to go to the database and lock the record.
Does someone have any Ideas how to do this in c#.net? User controls? ore is there a better way?
thanks
Paul
ps: sorry for my bad english
