kendo组件封装模板/组件使用

Question

是否可以通过 ng-content 或 TemplateRef 或类似方法来嵌入自定义列定义？我一直在通过站点 (http://www.telerik.com/kendo-angular-ui/components/grid/) 和 Angular2 child component as data 提供的 Kendo UI Grid plunker 进行测试，但无济于事。我也尝试过 ng-content select 但也没有。非常感谢任何帮助，谢谢！

@Component({
  selector: 'test-component',
  template: 
  `
    <kendo-grid [data]="Data">
    <kendo-grid-column></kendo-grid-column>
      // ??? // <ng-content kendo-grid-column></ng-content> // [object Object]
      // ??? // <kendo-grid-column ng-content></kendo-grid-column> // [object Object]
    </kendo-grid>
  `
})
export class TestComponent {
  @Input() Data: any;
}

@Component({
    selector: 'my-app',
    template: `
        <test-component [Data]="gridData">
          <kendo-grid-column field="ProductID" title="Product ID" width="120"></kendo-grid-column>
          <kendo-grid-column field="ProductName" title="Product Name"></kendo-grid-column>
          <kendo-grid-column field="UnitPrice" title="Unit Price" width="230"></kendo-grid-column>
          <kendo-grid-column field="Discontinued" width="120">
              <template kendoCellTemplate let-dataItem>
                  <input type="checkbox" [checked]="dataItem.Discontinued" disabled/>
              </template>
          </kendo-grid-column>
        </test-component>
    `
})
export class AppComponent { ... }

@rusev 在之前的评论中回答...这对我有用，谢谢！

GridComponent 正在使用ContentChildren 来选择定义的列， 这不适用于嵌入。一种可能的解决方法 - plnkr.co/edit/w6EgmZL5z8J6CvpjMl2h?p=preview

这是可以在 plunkr 中看到的答案

import { Component, Input, ContentChildren, ViewChild, ChangeDetectorRef } from '@angular/core';
import { ColumnComponent, GridComponent } from '@progress/kendo-angular-grid';

const resolvedPromise = Promise.resolve(null); //fancy setTimeout

@Component({
  selector: 'test-component',
  template: 
  `
    <kendo-grid [data]="Data">
    </kendo-grid>
  `
})
export class TestComponent {
  @Input() Data: any[];

  @ContentChildren(ColumnComponent) columns;
  @ViewChild(GridComponent) grid;

  constructor(private cdr: ChangeDetectorRef ) {}
  ngAfterContentInit() {
    resolvedPromise.then(() => { 
      this.grid.columns.reset(this.columns.toArray());
    });
  }
}

@Component({
    selector: 'my-app',
    template: `
        <test-component [Data]="gridData">
            <kendo-grid-column field="ProductID" title="Product ID" width="120"></kendo-grid-column>
        </test-component>
    `
})
export class AppComponent { ... }

要选择带有ng-content 的kendo-grid-column 元素，请使用：

<ng-content select="kendo-grid-column"></ng-content>

见this plunkr。
