I have just upload an experiment stack in the Slug's website: http://www.aslugontheroad.co.cc/index.php?option=com_phocadownload&view=category&download=8:experiment-013-doing-sum-in-a-column-of-a-data-grid&id=7:data-grid&Itemid=63 The experiment shows how doing a sum of three columns in a column of a data grid: - when the dg is filling in - when you change a value in one of the three columns. The stack using a custom column behavior. You can access to the script by clicking on the edit script button.
