问题:

Is is possible to transclude custom column definitions via ng-content or TemplateRef or similar? I've been testing via Kendo UI Grid plunker available at site (http://www.telerik.com/kendo-angular-ui/components/grid/) as well as Angular2 child component as data but to no avail. I've also tried it ng-content select but also nothing. Any help is greatly appreciated, thanks!

@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 { ... }

As answered by @rusev in a comment prior ... this will work for me, thanks !

The GridComponent is using ContentChildren to select defined columns, which does not work with transclusion. A possible workaround - plnkr.co/edit/w6EgmZL5z8J6CvpjMl2h?p=preview

This is the answer as can be seen in the plunkr

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 { ... }

To select the kendo-grid-column elements with a ng-content, use:

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

See this plunkr.
