Hello all. I have made small improvements on Craig Boyd's gridextras class. I thinkl is the best class ever for managing grids, but there are slight touches needed to make it perfect, so my idea is to put it as a project here. You can check the original work here:

And I guess the licence is very liberal based on Craig's words:
" Just have fun with GridExtras and see if it's useful to you and your applications. In a perfect world, you'd find some way to improve it (add additional export formats, provide a column lock feature, etc.). If you do improve GridExtras, I'd appreciate it if you would contact me and share the improvements you've implemented. Thank you in advanced to those of you that decide to do so."
