Using DB grids

Never tried any data with IW before, so if there are any secrets, please share.

Tried the demo with TIWjQDBGrid and it worked. But it's using a ClientDataset. Once I replaced that with a real DB connection, the grid just displays "Loading..." and nothing happens. Is it supposed to work?

So, how would you publish any data from the server to a grid?

Can it be editable in the grid, in place, as a VCL grid would do?

Or is this a totally different world and nothing is what it seems?
