Angularjs kendo 树视图未在 Kendo 弹出窗口中显示复选框

Angularjs kendo treeview not showing checboxes in Kendo popup

我正在使用 Kendo Window,其中显示 Kendo 带有复选框的 TreeView。问题是 treeview 呈现正确但复选框不显示。如果我在 Kendo Window 之外呈现树视图(即直接在我的页面中),那么它会正确显示复选框。

请帮助我,因为我卡住了。下面是我使用的代码:

<div kendo-tree-view k-options="treeOptions" k-data-source="treeDataSource"></div>


$scope.treeOptions = {
   checkboxes: {
      checkChildren: true
   }
};

此代码似乎工作正常:

<div kendo-window>
  <div kendo-tree-view k-options="treeOptions" k-data-source="treeDataSource"></div>
</div>
<script>
  angular.module("app", ["kendo.directives"]).controller("controller", function($scope) {
    $scope.treeOptions = {
      checkboxes: {
        checkChildren: true
      }
    };
    $scope.treeDataSource =  [
        { text: "Furniture", expanded: true, items: [
            { text: "Tables & Chairs" },
            { text: "Sofas" },
            { text: "Occasional Furniture" }
        ] },
        { text: "Decor", items: [
            { text: "Bed Linen" },
            { text: "Curtains & Blinds" },
            { text: "Carpets" }
        ] }
    ];
  });
</script>
