jqgrid在重新加载后应用过滤器？

Question

我正在使用jqgrid，一次加载数据，在本地排序和过滤，并在每次更新/插入/删除后进行刷新。它工作正常，除此之外，如果我使用过滤器（在网格顶部），过滤器在刷新后保持不变，但过滤器不会重新应用于新加载的数据。 我试图在用触发器（'reloadGrid'）重新加载网格后调用mygrid [0] .triggerToolbar（），但没有任何效果。

感谢任何帮助或指针:-)下面

代码：

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 
    url: '/public/Gadgets/LinkGadget/ProductLinks/' + lang,

else

} 

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

//jqgrid setting "loadonce: true" will reset datatype from json to local after grid has loaded. "datatype: local" 
// does not allow server reloads, therefore datatype is reset before trying to reload grid 
$("#list2").setGridParam({ datatype: 'json' }).trigger('reloadGrid'); 
//mygrid[0].clearToolbar(); 
lastsel = null; 

//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() { 
    reload(); 
}
