Я использую jqgrid, загружаю данные один раз, сортирую и фильтрую локально и выполняю обновление после каждого обновления / вставки / удаления.Он работает нормально, кроме того, что если я использую фильтр (поверх сетки), фильтр остается таким же после обновления, но фильтр не применяется повторно к вновь загруженным данным.Я пытался вызвать mygrid [0] .triggerToolbar () после перезагрузки сетки с триггером ('reloadGrid'), но эффекта нет.
Спасибо за любую помощь или указатели: -)
