Hi,

I try to find all the events attached to the elements put in the groupBy area after grouping the grid , but i cannot find any : 

I'm grouping the grid with any column. once its done, the element in the area has some features such as close/remove the group or sort the results. But it doesn't raised the usual event "groupedColumnsChanged".

If I add a new group to the first one, say with the columnB, i can after that reorder the grouping list directly from the area by directly dragging the columnB before the previous one. But again i didn't find the raised event on that kind of action. 

is there another way to listen to those events, or to execute some logic after ? how can i handle user interaction with the groupBy area element ?

Thank you for you help

Kind regards
