重新加载后从jqgrid保留过滤器，排序，展开，页面，选择

Question

我需要在jqgrid中自动刷新服务器中的数据10分钟。 刷新后我需要零售过滤，排序，子网格展开，页面，选定行（多个）。

我可以保留除页面和选定行之外的所有内容。在这里我只能做页面或选定的行。无法保留两者。只有一个适合我。

代码

      jQuery("#tblCompletedPriceList").jqGrid({
            url: $('#tblCompletedPriceList').attr("RequestUrl"),
            datatype: "json",
            mtype: "Get",
            hoverrows: false,
            colNames: CompletedColName,
            colModel: CompletedColModel,
            id: 'PriceListID',
            localReader: { id: 'PriceListID' },
            prmNames: { id: "PriceListID" },
            rowNum: 10,
            hidegrid: false,
            rownumbers: true,
            pager: '#CompletedPriceListGridPager',
            viewrecords: true,
            caption: "Completed Price List Queue",
            height: 'auto',
            scrollOffset: 0,
            gridview: true,
            shrinkToFit: true,
            autoencode: true,
            loadonce: true,
            ignoreCase: true,

                UnBlockUI();
                var $this = $(this);
                var selRowIds = jQuery('#tblCompletedPriceList').jqGrid('getGridParam', 'selarrow');
                postfilt = $this.jqGrid('getGridParam', 'postData').filters;
                postsord = $this.jqGrid('getGridParam', 'postData').sord;
                postsort = $this.jqGrid('getGridParam', 'postData').sidx;
                postpage = $this.jqGrid('getGridParam', 'postData').page;
                var selRowIds = jQuery('#tblCompletedPriceList').jqGrid('getGridParam', 'selarrrow');
                if ($this.jqGrid("getGridParam", "datatype") === "json") {
                    setTimeout(function () {
                        $this.jqGrid("setGridParam", {
                            datatype: "local",
                            postData: { filters: postfilt, sord: postsord, sidx: postsort },
                            search: true
                        });
                        $this.trigger("reloadGrid", [{ page: postpage }]);
                    }, 15);
                }
                if (expandedids != "") {
                    $("#tblCompletedPriceList").jqGrid('expandSubGridRow', expandedids);
                    expandedids = "";
                }


                if (selRowIds.length < 1) {
                    return false;
                } else {
                    var i, count;
                    for (i = 0, count = selRowIds.length; i < count; i++) {
                        jQuery('#tblCompletedPriceList').jqGrid('setSelection', selRowIds[i], false);
                    }
                }
            },
            beforeRequest: function () {
                $("#tblCompletedPriceList tr:has(.sgexpanded)").each(function () {
                    expandedids = $(this).attr('id');
                });
            }
    });

重新加载

window.setTimeout(refreshGrid, 600000);

    function refreshGrid() {
        $('#tblCompletedPriceList').setGridParam({ datatype: 'json' }).trigger("reloadGrid");
        window.setTimeout(refreshGrid, 600000);
    }
