Hi guys,
So here is what I am trying to do: I have a grid of people. Each cell represents a certain amount of time spent by the person on an activity. The header of the column represents the average time spent. Currently to do the average, I call a method to get all persons from the DB and then I make an average. But what I want to do is to dynamically modify this average depending on the filtering of the grid.
How can I do that? ListDataProvider isn’t modified when filtered so I found this solution to get the number of rows
grid.getDataProvider().size(new Query<>())
However this only returns the number of rows. What I want is to get access to each element of the cells in order to redo the calculation of the average.
Is there a way to do it?
