Hi,
the task I am currently working on is creating new form and passing the selected records from SalesTableListPage to the new form via menu item button. I already did that overriding the clicked method and init using a container. Now for the second part of the task I need to count the total quantity of all lines matching the query criteria and average price of all lines matching the query criteria and display it on the new form. (Meaning I have to count the quantity of items for the selected customer or item and the average price of those items). How do I do this?
