我知道剑道数据源中触发了哪些事件，但我想知道是否有人列出了事件触发的顺序。我试图在 read() 和 refresh() 之后重新过滤网格，但似乎无法使代码正常工作。它通过更改事件保存得很好，但我不知道在哪里实际尝试将过滤器插入到网格中，因此它将像保存之前一样被过滤

                    dataSource: {

                    serverSorting: false,   
                    batch: true,
                    pageSize: 50,   
                    change: function(e) {
                        dataSource = $("#grid").data("kendoGrid").dataSource;

使用远程操作时的顺序如下：

dataSource.requestStart

dataSource.requestEnd

dataBinding

dataBound

dataSource.change

所有都列在文档中。您还可以使用以下演示。我不确定您要达到什么目标，但我怀疑您正在尝试保持 Grid 状态，如此处所述。
