Question

我想知道是否有任何方法可以通过客户端过滤获得Cascade kendo DropDownList（绑定到远程数据）。我知道我可以使用主下拉列表的更改事件来处理级联效果并处理案例，但我想知道是否有＆＃34; kendo＆＃34;处理这种情况的方式。可能我可以设置一些我忽略的参数。

我认为这个例子会有所帮助：

category: <input id="category" />
product: <input id="product" />
var category = $("#category").kendoDropDownList({
    optionLabel: "Select category...",
    dataSource: [
        { CategoryID: 1, CategoryName: "Beverages" },
        { CategoryID: 2, CategoryName: "Condiments" },
        { CategoryID: 3, CategoryName: "Confections" }
    ],
    dataValueField: "CategoryID",
    dataTextField: "CategoryName"
}).data("kendoDropDownList");

var product = $("#product").kendoDropDownList({
    optionLabel: "Select product...",
    dataSource: [
        {"ProductID":35,"ProductName":"Steeleye Stout","CategoryID":1},
        {"ProductID":3,"ProductName":"Aniseed Syrup","CategoryID":2},
        {"ProductID":4,"ProductName":"Chef Anton's Cajun Seasoning","CategoryID":2},
        {"ProductID":5,"ProductName":"Chef Anton's Gumbo Mix","CategoryID":2},
        {"ProductID":6,"ProductName":"Grandma's Boysenberry Spread","CategoryID":2},
        {"ProductID":8,"ProductName":"Northwoods Cranberry Sauce","CategoryID":2},
        {"ProductID":16,"ProductName":"Pavlova","CategoryID":3},
        {"ProductID":19,"ProductName":"Teatime Chocolate Biscuits","CategoryID":3},
        {"ProductID":20,"ProductName":"Sir Rodney's Marmalade","CategoryID":3},
        {"ProductID":21,"ProductName":"Sir Rodney's Scones","CategoryID":3},
        {"ProductID":25,"ProductName":"NuNuCa Nuß-Nougat-Creme","CategoryID":3}                
    ],
    dataValueField: "ProductID",
    dataTextField: "ProductName",
    cascadeFrom: "category"
}).data("kendoDropDownList");
