>>It seems that I haven't really explained myself properly as this isn't what I'm looking for. I don't want the user to sort things in the grid by dragging the rows (although that may come in handy elsewhere).

Hi Tore,

the framework I use has a similar set up, but if I have a grid with 10 columns I don't want to have to create all the possible combinations of indexes that a user can select.
