Scenario to cover: the user tries to filter the grid not with each entered symbol but when the value in the filter cell is committed (Enter key is pressed) and the editor is closed. The CellValuePushed event is fired only for data cells and the FilterChanged event is fired with each keystroke but not when the editor is closed. A similar scenario is valid for the new row. There is no suitable event for capturing when a certain cell is updated in the new row as well.
