Thank you very much for the fast answer. The filtering is now working along with other settings, but still the input field for the filtered column in filter row is empty and thus there isn't an indication for the user that the grid has been filtered. Should we think of some custom solution or you can suggest us a quick workaround?
P.S. Понеже ми се струва че доста от хората, които отговарят са българи, ако пиша на български в този форум дали ще получа отговор?
