Ok, I'm new at this , have a grid of order items on an order page. I have a total field for the order items (qty * price). Want a total for the whole grid, the aggregate feature says "Aggregation is only supported in grids with an xpath source." There has to be a simple way to show the total for the grid, what's the easiest way?
Make sure the source for your grid is set to xpath in stead of the default database option.
