If you wish to calculate a value to be displayed in each row of a report, based on other values in the row and some other data, which method do you use? To which data element do you attach the script or Java event handler?

If I'm understanding what you're trying to do, you could just add a computed column in your dataSet or add a new binding to your table and do your scripting in the expression builder. If you're for sure wanting to access this from script, you'll need to use the onCreate script in the detail row. The onPrepare doesn't have access to the data. Hope this helps.

Does the onCreate in the detail row enable you to alter or set the value of the computed column?
