First of all, thank you for your tool, it helps a lot

So, I try to use jgrid and treegrid with local data but I could only make the grouping work without treegrid or the opposite.

For using treegrid with local data I've followed this tutorial (using the json read object): http://stackoverflow.com/quest.....local-data

Any clues? Can those two features work together?

Thank you in advance,
