我想知道如何在加载时按降序获取排序列。我在堆栈溢出中看到了一些问题/答案，但这完全取决于jqGrid配置。我没有让它工作......一旦从服务器收到数据，就需要在本地完成。
谢谢..

您使用loadonce: true选项。如果服务器（在您的情况下为'../websrvc/JqGrid.ashx'）应返回已排序数据。这是jqGrid的要求。我发布到trirand the suggestion来改变行为，但是jqGrid仍然没有对用loadonce: true选项加载的数据的排序做任何改变。
为了获得最佳效果，您的ASHX代码应获取sidx和sord个参数（context.Request["sidx"]，context.Request["sord"]）并返回所有网格行 sorted < / strong> sidx对应sord方向。
只有在服务器端进行排序时才会遇到实际问题，您可以在客户端进行排序。首先，您应该将sortname: 'StockDate'和sortorder: 'desc'设置为与您想要的排序结果相对应的值。如果您需要按Year列对网格进行排序，则应使用sortname: 'Year'。然后你应该在第一次加载后直接重新加载网格。您可以使用以下loadComplete
loadComplete: function () {
var $self = $(this);
if ($self.jqGrid("getGridParam", "datatype") === "json") {
// the code will be executed only at the first loading because jqGrid
// changes datatype to "local" after the first loading if we use
// loadonce option. We use setTimeout to allows jqGrid to make the first
// loading till the end and reload it AFTER that
setTimeout(function () {
$self.triggerHandler("reloadGrid");
}, 50);
}
}
更新 Free jqGrid jqGrid的分支，我自2014年底开发，有forceClientSorting: true选项，可以与loadonce: true结合使用。在客户端上排序和过滤的选项强制将在第一次从服务器加载时完成。换句话说，选项forceClientSorting: true替换了答案中描述的所有代码。原因forceClientSorting: true在loadComplete内重新加载网格时效果很快。
答案 1 :(得分：0)
相当简单，设置网格的属性： 例如：
sortname: 'ColumnNameToSortOn',
sortorder: "desc",
答案 2 :(得分：0)
设置sortname和sortorder不起作用。 你也需要setTimeout。 这有一个缺点：滚动不会工作，因为它不断重建网格似乎。 所以你再次跳到网格顶部。
