jqgrid在重新加載後應用過濾器？

Question

我正在使用jqgrid，一次加載數據，在本地排序和過濾，並在每次更新/插入/刪除後進行刷新。它工作正常，除此之外，如果我使用過濾器（在網格頂部），過濾器在刷新後保持不變，但過濾器不會重新應用於新加載的數據。 我試圖在用觸發器（'reloadGrid'）重新加載網格後調用mygrid [0] .triggerToolbar（），但沒有任何效果。

感謝任何幫助或指針:-)下面

代碼：

var lastsel; 
var mygrid; 
var currentLang; 

//setup grid with columns, properties, events 
function initGrid(lang, productData, resellerData, resellerSearchData) { 


    mygrid = jQuery("#list2").jqGrid({ 
    //data loading settings

//Used by initGrid - reloads grid 
function reload() { 

//jqgrid setting "loadonce: true" will reset datatype from json to local after grid has loaded. "datatype: local"

//Comments: after reload, toolbar filter is not applied to refreshed data. Tried row below without luck 
//mygrid[0].triggerToolbar();

    //after successful save, reload grid and deselect row 
function afterSave() {
