pass dropdown filter of data grid

Hi all, is it possible to somehow pass the chosen dropdown filter of da data grid?  Here is what this is about: I have different pages with data grids (xpath) of different entities which are all associated. All grids have the same Dropdown Filter ‘Event’ of the entity ‘event’. How can I create a function that a user selects his event on the first grid and this selection is set for all grids of all pages until you change it again?
