无法使 "Kendo UI for Angular 2" 个组件工作

Question

我正在尝试构建一个利用 "Kendo UI for Angular 2" 控件的演示应用程序，但我似乎只能让 Button 控件工作。所有其他控件要么显示错误，要么根本不显示。我真的需要一些帮助，这样我才能弄清楚该产品是否值得我们正在启动的新长期项目的成本。

在下面的示例中，我使用 Angular 2 来显示他们的按钮和下拉列表。只有按钮有效。请帮我让这个示例工作。我花了太长时间试图弄清楚这一点。谢谢！

@Component({
    selector: 'my-app',
    template: `
        <button kendoButton (click)="onButtonClick()" [primary]=true>Button!</button> This works!
        <kendo-dropdownlist [data]="listItems"></kendo-dropdownlist> This doesn't even display.

    styleUrls: [ '../node_modules/@progress/kendo-angular-buttons/dist/npm/css/main.css', '../node_modules/@progress/kendo-angular-dropdowns/dist/npm/css/main.css' ]
})

export class AppComponent {
   listItems: Array<string> = ['This', 'is', 'really', 'upsetting'];

   onButtonClick() {
        alert('The only working Kendo component');
    }
}

除了您的 systemjs.config.js 配置外，一切看起来都是正确的。您的包定义需要将地图与您定义的库相匹配。这是我的配置并且可以正常工作，只需将我的网格组件定义替换为您的组件定义即可。

systemjs.config.js

// map tells the System loader where to look for things
map: {
    'app': 'dist',
    '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
    ...
    '@progress/kendo-angular-intl': 'npm:@progress/kendo-angular-intl',
    '@progress/kendo-angular-grid': 'npm:@progress/kendo-angular-grid',
    '@telerik/kendo-intl': 'npm:@telerik/kendo-intl',
  },

  // packages tells the System loader how to load when no filename and/or no extension
  packages: {
    'app': {
      main: './app.main.js',
      defaultExtension: 'js'
    },
    ...
    '@progress/kendo-angular-intl': {
      main: './dist/npm/js/main.js',
      defaultExtension: 'js'
    },
    '@progress/kendo-angular-grid': {
      main: './dist/npm/js/main.js',
      defaultExtension: 'js'
    },
    '@telerik/kendo-intl': {
      main: './dist/npm/js/main.js',
      defaultExtension: 'js'
    }
  }
});

使用命令 npm install --save @telerik/kendo-theme-default.

安装 default Kendo theme (https://www.npmjs.com/package/@telerik/kendo-theme-default)

在 index.html 中指定 CSS 文件，所有控件将按预期显示。

<link rel="stylesheet" href="./node_modules/@telerik/kendo-theme-default/dist/all.css">
