Hi Syncfusion-Team,

i tried to add new columns to Grid with grid.colums.push.
This results in Error TS2349 in Visual Studio before compiling.

How have i to do this the right way?
Maybe you can show me an example that works. :)

<ejs-grid #testGrid id='grid' class="margin-top-10 expense-grid-margin pane" height='100%' width='100%'
          allowPaging='true' [allowSorting]="true" allowSelection='false'
          [dataSource]='jsonDataWebService.DataList' [editSettings]='editSettings' [toolbar]='toolbarValue'
          (created)='onGridCreated()' (actionBegin)='onGridActionBegin($event)' (actionComplete)='onGridActionComplete($event)'
        <e-column width='100' textAlign='Center'>
            <ng-template #template let-data>
                <button id="gridEdit" type="button" title="Edit" class="e-lib e-btn e-control e-flat e-icon-btn e-edit-delete e-editbutton" (click)='onGridButtonEditClicked($event)'>
                    <span class="e-btn-icon e-icons e-edit"></span>
                <button id="gridDelete" type="button" title="Delete" class="e-lib e-btn e-control e-flat e-icon-btn e-edit-delete e-deletebutton" (click)='onGridButtonDeleteClicked($event)'>
                    <span class="e-btn-icon e-icons e-delete"></span>

let c = <Column[]>
        [ new Column( { field: "Id", headerText: "ID", width: "75", isPrimaryKey: true } ), 
          new Column( { field: "Key", headerText: "Key", width: "300" } ), 
          new Column( { field: "Name", headerText: "Name", width: "300" } ), 
          new Column( { field: "DateCreated", headerText: "Date Created", width: "200" } )
forlet i: number = 0; i < c.length; i++ ) {
    this.grid.columns.push( c[ i ] );
        // Test 2
        this.grid.columns.push( c );
        // Test 3
        let gc = this.grid.columns;
forlet i: number = 0; i < gc.length; i++ ) {
    this.grid.columns.push( gc[ i ] );

Fehler TS2349 (TS) Ein Ausdruck, dessen Typ eine Aufrufsignatur fehlt, kann nicht aufgerufen werden. Der Typ "((...items: string[]) => number) | ((...items: Column[]) => number) | ((...items: ColumnModel[]) => number)" weist keine kompatiblen Aufrufsignaturen auf.

Hope for help,
habe a nice day,

Hi Peter, 
Greetings from Syncfusion support. 
You can update the Grid columns by using the below way. Please refer to the below code example and sample link for more information. 
    selector: 'app-root', 
    template: '<button (click)="click($event)">Columns</button> 
    <ejs-grid #grid [dataSource]='data' height='350'> 
            <e-column field='OrderID' headerText='Order ID' width='120' textAlign='Right'></e-column> 
            <e-column field='CustomerName' headerText='Customer Name' width='150'></e-column>           
export class AppComponent { 
    .  .  . 
    let c = <Column[]> 
        [  { field: 'OrderDate', headerText: 'Order Date', width: 130, format: 'yMd', textAlign: 'Right' }, 
                { field: 'Freight', width: 120, format: 'C2', textAlign: 'Right' }, 
                { field: 'ShippedDate', headerText: 'Shipped Date', width: 140, format: 'yMd', textAlign: 'Right' }, 
                { field: 'ShipCountry', headerText: 'Ship Country', width: 150 } 
        for( let i: number = 0; i < c.length; i++ ) { 
    (this.grid.columns as Column[]).push( c[ i ] ); 
Please get back to us if you need any further assistance on this.
