Tool bar in React Gantt component

2 Feb 202324 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.

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

  • 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.

You can check this video to learn about how to use custom toolbar in Gantt.

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.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent, Inject, Filter, Toolbar } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App(){
    let ganttInstance;
    const taskFields= {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
  };
  const toolbarOptions = [{text: 'Quick Filter', tooltipText: 'Quick Filter', id: 'toolbarfilter', align:'Right', prefixIcon: 'e-quickfilter' }];
 function toolbarClick(){
              ganttInstance.filterByColumn('TaskName', 'startswith', 'Identify');
        };
        return <GanttComponent dataSource={data} taskFields={taskFields}
        allowFiltering={true}  toolbar={toolbarOptions} toolbarClick={toolbarClick.bind(this)} height = '450px' ref={gantt => ganttInstance = gantt}>
         <Inject services={[Filter, Toolbar]} />
        </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));
import * as React from 'react';

  • 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.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { ClickEventArgs } from '@syncfusion/ej2-navigations';
import { GanttComponent, Inject, Toolbar } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App(){
    const taskFields = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks',
    dependency: 'Predecessor',
  };
  const toolbarOptions = ['ExpandAll', 'CollapseAll', { text: 'Test', tooltipText: 'Test',id: 'Test' }];
  function toolbarClick(args) {
       if (args.item.text === 'Test') {
        alert("Custom toolbar Click...");
      }
    };
        return <GanttComponent dataSource={data} taskFields={taskFields}  
        toolbar={toolbarOptions} toolbarClick={toolbarClick} height = '450px'>
            <Inject services={[Toolbar]} />
        </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { ClickEventArgs } from '@syncfusion/ej2-navigations';
import { GanttComponent, Inject, Toolbar } from '@syncfusion/ej2-react-gantt';

  };
  const toolbarOptions: any[] = ['ExpandAll', 'CollapseAll', { text: 'Test', tooltipText: 'Test',id: 'Test' }];
  function toolbarClick(args: ClickEventArgs): void {
       if (args.item.text === 'Test') {
        alert("Custom toolbar Click...");
      }
    };
        return <GanttComponent dataSource={data} taskFields={taskFields}  
        toolbar={toolbarOptions} toolbarClick={toolbarClick} height = '450px'>
            <Inject services={[Toolbar]} />

Enable/disable toolbar items

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

Add input elements in Toolbar

In Gantt toolbar, it is possible to add EJ2 editor elements like numeric text box, dropdown list and date picker components. The following code snippets explains how to add EJ2 editors in Gantt toolbar.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { NumericTextBox} from '@syncfusion/ej2-inputs';
import { GanttComponent, Inject, Toolbar } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App (){
    const taskFields = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
  };
  const toolbarOptions = [ { type: 'Input',template:new NumericTextBox({ format: 'c2', value:1 })} ];
        return <GanttComponent dataSource={data} taskFields={taskFields}  
        toolbar={toolbarOptions} height = '400px'>
            <Inject services={[Toolbar]} />
        </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { NumericTextBox} from '@syncfusion/ej2-inputs';
import { GanttComponent, Inject, Toolbar } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
function App (){
    const taskFields: any = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    child: 'subtasks'
  };
  const toolbarOptions: any[] = [ { type: 'Input',template:new NumericTextBox({ format: 'c2', value:1 })} ];
        return <GanttComponent dataSource={data} taskFields={taskFields}  
        toolbar={toolbarOptions} height = '400px'>
            <Inject services={[Toolbar]} />
        </GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));
