I'm sure that I'm not the only one out there that often has to use 2 iGrids to allow totals to be shown. This requires tedious sync between the two grids to ensure that the col widths remain the same between the two. Also have to set the horizontal scrollbar to be see-through so that if it appears, that it does not obscure the totals etc...

Technically, I don't think it would be hard to replicate the header rows functionality into footer rows (which always appear at the bottom). Or perhaps simpler would be to allow a header to be fixed at the bottom?

The multi-row footer section with automatic totals calculation and cell merging is now available as a built-in feature in iGrid.NET 5.0.
