    Would it be possible to create a hierarchical datasource not from two endpoints, as the example shows below, but from two functions returning json.  Could the two transport sections below be replaced with data (as in data: getProductData()) functions which return data that the dataSource then "combines" the way it  does with remote endpoints?  If this is possible, how would the function returning the second level data (like products below) look?

    var Categories = new kendo.data.HierarchicalDataSource({
        transport: {
            read: {
                url: "http://demos.kendoui.com/service/Categories"
            }
        },
        schema: {
            model: {
                hasChildren: "Products",
                id: "CategoryID",
                children: {
                    transport: {
                        read: {
                            url: "http://demos.kendoui.com/service/Products"
                        }
                    },
                    schema: {
                        model: {
                            id: "ProductID",
                            hasChildren: false
                        }
                    }
                }
            }
        }
    });

    Hello Bill,

    You can use functions for the read operations, as inherited from the DataSource (see its online docs). For an example of this functionality, consider this jsBin.

    All the best,
