Toolbar in Angular Gantt component

27 Apr 202424 minutes to read

The Gantt component provides the toolbar support to handle Gantt actions. The toolbar property accepts the collection of built-in toolbar items and ItemModel objects for custom toolbar items.

To use toolbar feature, inject the ToolbarService in the provider section of AppModule.

Built-in toolbar items

Built-in toolbar items execute standard actions of the Gantt component, and these items can be added to toolbar by defining the toolbar as a collection of built-in items. It renders the button with icon and text.

The following table shows built-in toolbar items and its actions.

Built-in Toolbar Items	Actions
ExpandAll	Expands all the rows.
CollapseAll	Collapses all the rows.
Add	Adds a new record.
Edit	Edits the selected record.
Indent	Indent the selected record to one level.
Outdent	Outdent the elected record to one level.
Update	Updates the edited record.
Delete	Deletes the selected record.
Cancel	Cancels the edit state.
Search	Searches the records by the given key.
PrevTimeSpan	Navigate the Gantt timeline to previous time span.
NextTimeSpan	Navigate the Gantt timeline to Next time span.

• The toolbar has options to define both built-in and custom toolbar items.

Custom toolbar items

Custom toolbar items can be added to the toolbar by defining the toolbar property as a collection of ItemModels.
Actions for this customized toolbar items are defined in the toolbarClick event.

By default, the custom toolbar items are at left position. You can change the position by using the align property. In the following sample, the Quick Filter toolbar item is positioned at right.

• The toolbar has options to define both built-in and custom toolbar items.
• If a toolbar item does not match the built-in items, it will be treated as a custom toolbar item.

Built-in and custom items in toolbar

The Gantt component has an option to use both built-in and custom toolbar items at the same time.

In the following example, the ExpandAll and CollapseAll are built-in toolbar items and Test is the custom toolbar item.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { GanttModule } from '@syncfusion/ej2-angular-gantt'
import { FilterService, ToolbarService } from '@syncfusion/ej2-angular-gantt'




import { Component, ViewEncapsulation, OnInit } from '@angular/core';
import { Gantt } from '@syncfusion/ej2-gantt';
import { ToolbarItem } from '@syncfusion/ej2-angular-gantt';
import { ClickEventArgs } from '@syncfusion/ej2-navigations';
import { editingData } from './data';

@Component({
imports: [
         GanttModule
    ],

providers: [FilterService, ToolbarService],
standalone: true,
    selector: 'app-root',
    template:
       `<ejs-gantt id="ganttDefault" height="430px" [dataSource]="data" [taskFields]="taskSettings" [toolbar]="toolbar" [columns]="columns" (toolbarClick)="toolbarClick($event)"></ejs-gantt>`,
    encapsulation: ViewEncapsulation.None
})
export class AppComponent{
    // Data for Gantt
    public data?: object[];
    public taskSettings?: object;
    public columns?: object[];
    public toolbar?: any;
    public ngOnInit(): void {
        this.data = editingData;
        this.taskSettings = {
            id: 'TaskID',
            name: 'TaskName',
            startDate: 'StartDate',
            endDate: 'EndDate',
            duration: 'Duration',
            progress: 'Progress',
            dependency: 'Predecessor',
            child: 'subtasks'
        };
        this.columns = [
            { field: 'TaskID', headerText: 'Task ID', textAlign: 'Left', width: '100' },
            { field: 'TaskName', headerText: 'Task Name', width: '250' },
            { field: 'StartDate', headerText: 'Start Date', width: '150' },
            { field: 'Duration', headerText: 'Duration', width: '150' },
            { field: 'Progress', headerText: 'Progress', width: '150' },
        ];
        this.toolbar =  ['ExpandAll', 'CollapseAll', { text: 'Click', tooltipText: 'Click',id: 'Click' } ];
    }
    public toolbarClick(args: ClickEventArgs): void {
        if (args.item.text === 'Click') {
            alert("Custom toolbar click...");
            }
            };
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Enable/disable toolbar items

You can enable or disable the toolbar items by using the enableItems method.

export class AppComponent{
    // Data for Gantt
    public data?: object[];
    public taskSettings?: object;

    @ViewChild('gantt', {static: true})
    public ganttObj?: GanttComponent| any;
    public ngOnInit(): void {
        this.data = editingData;
        this.taskSettings = {
            id: 'TaskID',

        if (args.item.text === 'ClearFilter') {
            this.ganttObj.clearFiltering();
            }
        };
    enable(): void {
        this.ganttObj.toolbarModule.enableItems(['QuickFilter', 'ClearFilter'], true);// enable toolbar items.
        }
        disable(): void {
            this.ganttObj.toolbarModule.enableItems(['QuickFilter', 'ClearFilter'], false);// disable toolbar items.
            }
}

Add input elements in toolbar

In the Gantt toolbar, you can add EJ2 editor elements like numeric text box, drop-down list, and date picker controls. The following code snippets demonstrates how to add EJ2 editors to the Gantt toolbar.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { GanttModule } from '@syncfusion/ej2-angular-gantt'
import { ToolbarModule } from '@syncfusion/ej2-angular-navigations'
import { ToolbarService } from '@syncfusion/ej2-angular-gantt'




import { Component, ViewEncapsulation, OnInit } from '@angular/core';
import { Gantt } from '@syncfusion/ej2-gantt';
import {Toolbar} from '@syncfusion/ej2-navigations';
import { NumericTextBox} from '@syncfusion/ej2-inputs';
import { ToolbarItem } from '@syncfusion/ej2-angular-gantt';

@Component({
imports: [
         GanttModule, ToolbarModule
    ],

providers: [ToolbarService],
standalone: true,

    template:
       `

        </e-items>
        </ejs-toolbar>
        <ejs-gantt id="ganttDefault" height="430px" [dataSource]="data" [taskFields]="taskSettings"></ejs-gantt>`,
    encapsulation: ViewEncapsulation.None
})
export class AppComponent{
    // Data for Gantt
    public data?: object[];
    public taskSettings?: object;
