I have a ListView with with a Gridview and for a number of the columns I need to have two rows of data. the top lone has the items amount and the bottom with that amount multiplied by the quantity. I can get the top amount to show up just fine, but the bottom amount does not show. I have place breaks in the back end parts to make sure that the correct amount is being pulled and it is returning the right number, but it does not show up when I run the program.
