KendoGrid/Angular：无法动态创建网格列/数据

Question

In this plunk我有一个空网格（没有列）。当我点击“构建网格”时，我需要添加列（从数组中获取）并向表中添加一行。

问题是列没有添加到网格中，有什么想法吗？如果我尝试刷新网格，则会收到 undefined 错误。

HTML：

<button ng-click="buildGrid()">Build Grid</button>
<div kendo-grid="grid" k-options="gridOptions" k-data-source="ds"></div>

Javascript：

var app = angular.module("app", [ "kendo.directives" ]);

function MyCtrl($scope) {

    $scope.ds = []

    $scope.colsList =  [{ name: "col1" },
                        { name: "col2" },
                        { name: "col3" },
                        { name: "col4" }];


  var gridCols = [];

    $scope.gridOptions = {
            columns: gridCols
  };


$scope.buildGrid = function() {

        $scope.data = {};

        for (var x=0;x<$scope.colsList.length;x++) {
            var col = {};
            col.field = $scope.colsList[x].name;
            col.title = $scope.colsList[x].name;
            $scope.data[col.field] = "" + (1111 * (x+1));
            gridCols.push(col);
        }

        // add one row to the table
        $scope.ds.push($scope.data);
        //$scope.grid.refresh();

    };  
}

您需要使用 k-rebind 以便重新初始化网格（您不能在现有网格上动态设置列）：

<div kendo-grid="grid" 
     k-options="gridOptions" 
     k-data-source="ds" 
     k-rebind="gridOptions"></div>
