在Kendo的PushCreate兒童節點HierarchicalDataSource

Question

我試圖展示一個配置了遠程數據的Kendo TreeView，但預先填充了直接從html加載的數據的前兩個級別。

對於這一點，我想用的劍道的DataSource pushCreate方法將初始元素添加到樹：

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，元素添加到根級的孩子（你可以看到這運行here）。

有一個schema.model.children配置來設置保存子元素內的子元素的屬性，我可以一次添加所有，但如果我使用它，那麼dataSource將停止使用遠程數據（您可以看到運行here ）。

所以問題是，有沒有辦法使用pushCreate將元素添加爲HierarchicalDataSource中另一個元素的子元素？

我找到了答案，同時書面方式的問題:)

好像如果我只是使用items作爲孩子的關鍵，我並不需要指定schema.model.children選項，樹欲靜與遠程工作數據：

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。

我不知道這是否是和意想不到的功能，但可用於將一個完整的子樹添加到根（這解決了我的問題）。然而，問題仍然存在，我可以使用pushCreate將子元素添加到另一個？

你可以通過追加節點元素append來做到這一點。看telerik的這個例子：http://dojo.telerik.com/AjIti/32
