:) Wish all other things will be as easy... So far I am a bit discouraged. I spent quite an amount of time achieving very little so far and I am thinking if I should throw to the garbage that working form I have and try something different. For now I sort of put one form aside and will be playing with another and jquery Data Table. If this will be easier and I'll get it working the way I want, I'll re-design the other one also the same way.

I like the look of flexigrid, but certain things I still haven't figured out myself and asking in flexigrid user group didn't lead to any answer - looks like this group is only for questions and very rarely questions get answers.
