I think you should first create a new DataSource (see http://demos.kendoui.com/web/datasource/remote-data.htmlfor remote data)
我认为你应该首先创建一个新的数据源（远程数据见http://demos.kendoui.com/web/datasource/remote-data.html）
var dataSource = new kendo.data.DataSource({
data: [
{ name: "John Doe", age: 33 }
]
});
And then append it to the grid by using the setDataSource method (http://docs.kendoui.com/api/web/grid#methods-setDataSource)
然后使用 setDataSource 方法（http://docs.kendoui.com/api/web/grid#methods-setDataSource）将其附加到网格
var grid = $("#grid").data("kendoGrid");
grid.setDataSource(dataSource);

Since you want to change the action for your read then you can just do that. According to this questionyou could just set the dataSource Read url and refresh your grid data with something like that:
既然你想改变你的阅读动作，那么你就可以做到这一点。根据这个问题，您可以设置 dataSource Read url 并使用以下内容刷新您的网格数据：
var grid = $("#grid").data("kendoGrid");
grid.dataSource.transport.options.read.url = "newUrlPath";
grid.dataSource.read();
grid.refresh();
If you don't actually want to change your dataSource but your data and possibly get your list of items from some ajax request as json then I will write down the way I do it as an example in case someone wants it.
如果您实际上不想更改您的数据源而是您的数据，并且可能从某个 ajax 请求中获取您的项目列表作为 json 那么我将写下我的方式作为示例，以防有人需要它。
var jsonData = ... // From some ajax response
var newKendoDatasource = newKendoDS(jsonData);
$("#grid").data("kendoGrid").dataSource.data(newKendoDatasource._data);
The function is like the above pretty much
功能和上面差不多
function newKendoDS(ndata) {
var datasource = new kendo.data.DataSource({ data: ndata });
datasource.read(); // In order to refresh
return datasource;
}
