Good points. In case of multiple textboxes I guess we need a container based class which would allow to save value in a field using container's LostFocus (I guess). I also need a way to display correct value. And finally, in my table I store duration in minutes, so I would need to convert hh:mm to mm.

Anyway, for now I put the problem aside and working on something else right now. It's also a good idea to go out and take some lunch...
