    public toolbarSettings: any;
    constructor() {
        //...
        this.toolbarSettings = {
            showToolbar: true,
            toolbarItems: [
                ej.TreeGrid.ToolbarItems.Add,
                ej.TreeGrid.ToolbarItems.Edit,

• text- To insert the custom icons in toolbar using CSS class name selector.

• templateID-To insert the custom icons in toolbar using script templates. Using this property we can bind HTML elements and other EJ controls to TreeGrid toolbar.

• tooltipText-Displays tooltip text for the custom icons.

To insert EJ Controls in TreeGrid toolbar we need to initiate the control in create client side event.In toolbarClick client side event we can bind actions to the custom toolbar items.

        <input id="dropdownContainer" />
    </script>

JAVASCRIPT

<ej-treegrid id="TreeGridControl" (toolbarClick)="toolbarClick($event)" (create)="create($event)" [toolbarSettings]="toolbarSettings"
    //...>
</ej-treegrid>

JAVASCRIPT

import {Component} from '@angular/core';

@Component({
    selector: 'ej-app',
    templateUrl: 'app/app.component.html',
    styleUrls: ['app/app.component.css']
})
export class AppComponent {
    public toolbarSettings: any;

    constructor() {
        //...
        this.toolbarSettings = {
            showToolbar: true,
            customToolbarItems: [{
                    templateID: "#ColumnVisibility",
                    tooltipText: "Column Visibility"
                },
                {
                    text: "Reset",
                    tooltipText: "Reset"
                }
            ],
        }
    }
    toolbarClick(sender) {
        if (sender.itemName == "Reset") {
            //we can bind the custom actions here
