In my GridView, I have 3 columns.
3. Percentage (Amount/Quantity)
For the detail records, I am able to calculate the Percentage value in my business object. I was able to add column totals for Quantity and Amount; however, I cannot find a way to do the Percentage calculation. The Percentage calculation is SUM(Amount) / SUM(Quantity). Is this possible? How do I add a column total that is a calculation based on other column totals?
