javascript - 如何使用 Kendo UI Grid 的 SetDataSource 方法

Question

有没有人能够使用剑道 UI 网格的 setdatasource 方法？我相信这用于分配可以在后期分配给网格的数据源，也用于网格刷新目的。但是我找不到任何合适的文档来解释如何使用此方法并制作可刷新的网格。

我正在尝试通过远程 ajax 调用更新我的数据源。我还假设它应该在通过将 autosync 属性设置为 true 来更新源时自动刷新。每次单击日历控件时，我都会将日期值传递给 GetRemoteData 函数，以便通过 ajax 请求更新数据。

这暂时不起作用。关于解决方案的任何线索？

我的看法

    $('#calendarContainer').kendoCalendar({
        format: "dd/MM/yyyy",
        culture: "en-GB",
        change: onDateChange
    });


 function onDateChange() {
        var selectedDate = kendo.toString(this.value(), 'dd/MM/yyyy');

        GetRemoteData(selectedDate);
        /*
         $("#grid").data("kendoGrid").dataSource.data(bob);
         $("#grid").data("kendoGrid").dataSource.read();
        */
    }



   $('#grid').kendoGrid({

Answer 1

到目前为止你尝试了什么？这是非常基本的。

例子:

var ddl = $('#testDropDown').data("kendoDropDownList");
var otherDropDownList= $('#otherDropDown').data("kendoDropDownList");

var ds = new kendo.data.DataSource();
ds.data(otherDropDownList.dataSource.data()); // set new DataSource to otherDropDown's data source then filter it
ds.filter(
     {
         field: "Id",
         operator: "eq",
         value: parseInt(id)
     }
)

ddl.setDataSource(ds);

显然，无论您遇到哪种情况，这一切都会有所不同。

网格更新

var ds = new kendo.data.DataSource();
var grid = $('#grid').data("kendoGrid");

grid.setDataSource(ds); // sets to a blank dataSource

或者，将此数据源与另一个网格一起使用？

var gridDataSource = $('#grid').data("kendoGrid").dataSource;
var secondGrid = $('#secondGrid').data("kendoGrid");

secondGrid.setDataSource(gridDataSource);
