I had to make a list with all the hours from multiple users in a company. The list has the following columns: title, product, comment, start-time, end-time, duration. The header has 2 filters and a datepicker filter. I need to display the total durations (last column) in a partial (above table), based on filtered list. It's something about onFilterUpdate. Is there a way to bind an event or do something to have the result list and count duration and display it on filter update? If yes, how? I tried listFilterExtendScopes, but have no idea how to get the query results through it.
