在Kendo的PushCreate儿童节点HierarchicalDataSource

Question

我试图展示一个配置了远程数据的Kendo TreeView，但预先填充了直接从html加载的数据的前两个级别。

对于这一点，我想用的剑道的DataSource pushCreate方法将初始元素添加到树：

homogeneous = new kendo.data.HierarchicalDataSource({ 
    transport: { read: { url: serviceRoot + "/Employees", dataType: "jsonp" } }, 
    schema: { 
     model: { 
      id: "EmployeeId", 
      hasChildren: "HasEmployees" 
     } 
    } 
}); 

// Adding root 
homogeneous.pushCreate({"EmployeeId":2,"FullName":"Andrew Fuller","HasEmployees":true,"ReportsTo":null}); 

// Adding children 
homogeneous.pushCreate([ 
    {"EmployeeId":1,"FullName":"Nancy Davolio","HasEmployees":false,"ReportsTo":2}, 
    {"EmployeeId":3,"FullName":"Janet Leverling","HasEmployees":false,"ReportsTo":2}, 
    {"EmployeeId":4,"FullName":"Margaret Peacock","HasEmployees":false,"ReportsTo":2}, 
    {"EmployeeId":5,"FullName":"Steven Buchanan","HasEmployees":true,"ReportsTo":2}, 
    {"EmployeeId":8,"FullName":"Laura Callahan","HasEmployees":false,"ReportsTo":2} 
]); 

$("#treeview").kendoTreeView({ 
    dataSource: homogeneous, 
    dataTextField: "FullName" 
}); 

然而，元素添加到根级的孩子（你可以看到这运行here）。

有一个schema.model.children配置来设置保存子元素内的子元素的属性，我可以一次添加所有，但如果我使用它，那么dataSource将停止使用远程数据（您可以看到运行here ）。

所以问题是，有没有办法使用pushCreate将元素添加为HierarchicalDataSource中另一个元素的子元素？

我找到了答案，同时书面方式的问题:)

好像如果我只是使用items作为孩子的关键，我并不需要指定schema.model.children选项，树欲静与远程工作数据：

homogeneous.pushCreate(
    {"EmployeeId":2,"FullName":"Andrew Fuller","HasEmployees":true,"ReportsTo":null, 
     "items": [ 
      {"EmployeeId":1,"FullName":"Nancy Davolio","HasEmployees":false,"ReportsTo":2}, 
      {"EmployeeId":3,"FullName":"Janet Leverling","HasEmployees":false,"ReportsTo":2}, 
      {"EmployeeId":4,"FullName":"Margaret Peacock","HasEmployees":false,"ReportsTo":2}, 
      {"EmployeeId":5,"FullName":"Steven Buchanan","HasEmployees":true,"ReportsTo":2}, 
      {"EmployeeId":8,"FullName":"Laura Callahan","HasEmployees":false,"ReportsTo":2} 
     ] 
    } 
); 

Here's the working example。

我不知道这是否是和意想不到的功能，但可用于将一个完整的子树添加到根（这解决了我的问题）。然而，问题仍然存在，我可以使用pushCreate将子元素添加到另一个？

你可以通过追加节点元素append来做到这一点。看telerik的这个例子：http://dojo.telerik.com/AjIti/32
