Editor template in React Schedule component

25 Jul 202424 minutes to read

Scheduler makes use of popups and dialog to display the required notifications, as well as includes an editor window with event fields for making the appointment creation and editing process easier. You can also easily customize the editor window and the fields present in it, and can also apply validations on those fields.

Event editor

The editor window usually opens on the Scheduler, when a cell or event is double clicked. When a cell is double clicked, the detailed editor window opens in “Add new” mode, whereas when an event is double clicked, the same is opened in an “Edit” mode.

In mobile devices, you can open the detailed editor window in edit mode by clicking the edit icon on the popup, that opens on single tapping an event. You can also open it in add mode by single tapping a cell, which will display a + indication, clicking on it again will open the editor window.

You can also prevent the editor window from opening, by rendering Scheduler in a readonly mode or by doing code customization within the popupOpen event.

You can change the header title and the text of buttons displayed at the footer of the editor window by changing the appropriate localized word collection used in the Scheduler.

How to change the label text of default editor fields

To change the default labels such as Subject, Location and other field names in the editor window, make use of the title property available within the field option of eventSettings.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { ScheduleComponent, Day, Week, TimelineViews, Month, ViewsDirective, ViewDirective, Inject } from '@syncfusion/ej2-react-schedule';
import { scheduleData } from './datasource';
const App = () => {
  const fieldsData = {
    id: 'Id',
    subject: { name: 'Subject', title: 'Event Name' },
    location: { name: 'Location', title: 'Event Location' },
    description: { name: 'Description', title: 'Event Description' },
    startTime: { name: 'StartTime', title: 'Start Duration' },
    endTime: { name: 'EndTime', title: 'End Duration' }
  }
  const eventSettings = { dataSource: scheduleData, fields: fieldsData };

  return (<ScheduleComponent width='100%' height='500px' selectedDate={new Date(2018, 1, 15)} eventSettings={eventSettings}>
    <ViewsDirective>
      <ViewDirective option='TimelineDay' />
      <ViewDirective option='Day' />
      <ViewDirective option='Week' />
      <ViewDirective option='Month' />
    </ViewsDirective>
    <Inject services={[Day, Week, TimelineViews, Month]} />
  </ScheduleComponent>);
}

Field validation

It is possible to validate the required fields of the editor window from client-side before submitting it, by adding appropriate validation rules to each field. The appointment fields have been extended to accept both string and object type values. To perform validations, it is necessary to specify object values for the event fields.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { ScheduleComponent, Day, Week, WorkWeek, Month, Agenda, Inject } from '@syncfusion/ej2-react-schedule';
import { scheduleData } from './datasource';
const App = () => {
    const minValidation = (args) => {
        return args['value'].length >= 5;
    };
    const fieldsData = {
        id: 'Id',
        subject: { name: 'Subject', validation: { required: true } },
        location: { name: 'Location', validation: { required: true } },
        description: {
            name: 'Description', validation: {
                required: true, minLength: [minValidation, 'Need atleast 5 letters to be entered']
            }
        },
        startTime: { name: 'StartTime', validation: { required: true } },
        endTime: { name: 'EndTime', validation: { required: true } }
    }
    const eventSettings = { dataSource: scheduleData, fields: fieldsData };

    return (<ScheduleComponent width='100%' height='500px' selectedDate={new Date(2018, 1, 15)} eventSettings={eventSettings}>
        <Inject services={[Day, Week, WorkWeek, Month, Agenda]} />

Applicable validation rules can be referred from form validation documentation.

Add additional fields to the default editor

The additional fields can be added to the default event editor by making use of the popupOpen event which gets triggered before the event editor opens on the Scheduler. The popupOpen is a client-side event that triggers before any of the generic popups opens on the Scheduler. The additional field (any of the form elements) should be added with a common class name e-field, so as to handle and process those additional data along with the default event object. In the following example, an additional field Event Type has been added to the default event editor and its value is processed accordingly.

import * as ReactDOM from 'react-dom';

Customizing the default time duration in editor window

In default event editor window, start and end time duration are processed based on the interval value set within the timeScale property. By default, interval value is set to 30, and therefore the start/end time duration within the event editor will be in a 30 minutes time difference. You can change this duration value by changing the duration option within the popupOpen event as shown in the following code example.

import * as ReactDOM from 'react-dom';
import * as React from 'react';
import { ScheduleComponent, ViewsDirective, ViewDirective, Day, Week, WorkWeek, Month, Inject } from '@syncfusion/ej2-react-schedule';
import { scheduleData } from './datasource';
const App = () => {
  const eventSettings = { dataSource: scheduleData };

  const onPopupOpen = (args) => {
    if (args.type === 'Editor') {
      args.duration = 60;
    }
  }
  return (<ScheduleComponent width='100%' height='550px' selectedDate={new Date(2018, 1, 15)} eventSettings={eventSettings} popupOpen={onPopupOpen}>
    <ViewsDirective>
      <ViewDirective option='Day' />
      <ViewDirective option='Week' />
      <ViewDirective option='WorkWeek' />
      <ViewDirective option='Month' />
    </ViewsDirective>
    <Inject services={[Day, Week, WorkWeek, Month]} />
  </ScheduleComponent>);
};
const root = ReactDOM.createRoot(document.getElementById('schedule'));
root.render(<App />);
import * as ReactDOM from 'react-dom';
import * as React from 'react';
import {
  ScheduleComponent, ViewsDirective, ViewDirective, Day, Week, WorkWeek, Month, PopupOpenEventArgs, Inject
} from '@syncfusion/ej2-react-schedule';
import { scheduleData } from './datasource';

const App = () => {
  const eventSettings = { dataSource: scheduleData };

  const onPopupOpen = (args: PopupOpenEventArgs): void => {
    if (args.type === 'Editor') {
      args.duration = 60;
    }
  }
  return (<ScheduleComponent width='100%' height='550px' selectedDate={new Date(2018, 1, 15)}
    eventSettings={eventSettings} popupOpen={onPopupOpen} >
    <ViewsDirective>
      <ViewDirective option='Day' />
      <ViewDirective option='Week' />
      <ViewDirective option='WorkWeek' />
      <ViewDirective option='Month' />
    </ViewsDirective>
    <Inject services={[Day, Week, WorkWeek, Month]} />
  </ScheduleComponent>)
};
const root = ReactDOM.createRoot(document.getElementById('schedule'));
root.render(<App />);

How to prevent the display of editor and quick popups

It is possible to prevent the display of editor and quick popup windows by passing the value true to cancel option within the popupOpen event.

In case, if you need to prevent only specific popups on Scheduler, then you can check the condition based on the popup type. The types of the popup that can be checked within the popupOpen event are as follows.

Type Description
Editor For Detailed editor window.
QuickInfo For Quick popup which opens on cell click.
EditEventInfo For Quick popup which opens on event click.
ViewEventInfo For Quick popup which opens on responsive mode.
EventContainer For more event indicator popup.
RecurrenceAlert For edit recurrence event alert popup.
DeleteAlert For delete confirmation popup.
ValidationAlert For validation alert popup.
RecurrenceValidationAlert For recurrence validation alert popup.

Customizing timezone collection in the editor window

By default, the timezone collections in the editor window have been loaded with built-in timezone collections. Now we can be able to customize the timezone collections using the timezoneDataSource property with the collection of TimezoneFields data.

import * as React from 'react';
import * as ReactDOM from 'react-dom';

        EndTime: new Date(2018, 1, 15, 12, 30),
        IsAllDay: false
    }, {
        Id: 2,
        Subject: 'Blue Moon Eclipse',

        IsAllDay: false
    }];
    const eventSettings = { dataSource: data };

    return (<ScheduleComponent height='550px' selectedDate={new Date(2020, 1, 15)} eventSettings={eventSettings} timezoneDataSource={[

Customizing event editor using template

The event editor window can be customized by making use of the editorTemplate option. Here, the custom window design is built with the required fields using the script template and its type should be of text/x-template.

Each field defined within template should contain the e-field class, so as to allow the processing of those field values internally. The ID of this customized script template section is assigned to the editorTemplate option, so that these customized fields will be replaced onto the default editor window.

Note: e-field class only applicable for DropDownList, DateTimePicker, MultiSelect, DatePicker, CheckBox and TextBox components. Since we have processed the field values internally for the above mentioned components.

As we are using our Syncfusion sub-components within our editor using template in the following example, the custom defined form elements needs to be configured as required Syncfusion components such as DropDownList and DateTimePicker within the popupOpen event. This particular step can be skipped, if the user needs to simply use the usual form elements.

The editor window’s header and footer can be enhanced with custom designs using the editorHeaderTemplate and editorFooterTemplate options. To achieve this, create a script template that includes the necessary fields. Ensure that the template type is set to text/x-template.

In this demo, we tailor the editor’s header according to the appointment’s subject field using the editorHeaderTemplate. Furthermore, we make use of the editorFooterTemplate to handle the functionality of validating specific fields before proceeding with the save action or canceling it if validation requirements are not met.

How to save the customized event editor using template

The e-field class is not added to each field defined within the template, so you should allow to set those field values externally by using the popupClose event.

Note: You can allow to retrieve the data only on the save and delete option. Data cannot be retrieved on the close and cancel options in the editor window.

The following code example shows how to save the customized event editor using a template by the popupClose event.

import * as ReactDOM from 'react-dom';
import * as React from 'react';
import { useRef } from 'react';
import { ScheduleComponent, ViewsDirective, ViewDirective, Day, Week, WorkWeek, Month, Agenda, Inject } from '@syncfusion/ej2-react-schedule';
import { isNullOrUndefined } from '@syncfusion/ej2-base';
import { DateTimePickerComponent } from '@syncfusion/ej2-react-calendars';
import { DropDownListComponent } from '@syncfusion/ej2-react-dropdowns';
import { scheduleData } from './datasource';
const App = () => {
  const startObj = useRef(null);
  const endObj = useRef(null);
  const eventSettings = { dataSource: scheduleData };

  const onPopupOpen = (args) => {
    if (args.type === 'Editor') {
      let subjectElement = args.element.querySelector('#Summary');
      if (subjectElement) {
        subjectElement.value = args.data.Subject || "";
      }
      let statusElement = args.element.querySelector('#EventType');
      if (statusElement) {
        statusElement.setAttribute('name', 'EventType');
      }

How to change the watermark text of quick popup subject

By default, Add Title text is displayed on the subject field of quick popup. To change the default watermark text, change the value of the appropriate localized word collection used in the Scheduler.

L10n.load({
    'en-US': {
        'schedule': {
          'addTitle' : 'New Title'
        }
    }
});

Customizing quick popups

The look and feel of the built-in quick popup window, which opens when single clicked on the cells or appointments can be customized by making use of the quickInfoTemplates property of the Scheduler. There are 3 sub-options available to customize them easily,

  • header - Accepts the template design that customizes the header part of the quick popup.
  • content - Accepts the template design that customizes the content part of the quick popup.
  • footer - Accepts the template design that customizes the footer part of the quick popup.

The quick popup in adaptive mode can also be customized using quickInfoTemplates using e-device class.

More events indicator and popup

When the number of appointments count that lies on a particular time range * default appointment height exceeds the default height of a cell in month view and all other timeline views, a + more text indicator will be displayed at the bottom of those cells. This indicator denotes that the cell contains few more appointments in it and clicking on that will display a popup displaying all the appointments present on that day.

To disable this option of showing popup with all hidden appointments, while clicking on the text indicator, you can do code customization within the popupOpen event.

The same indicator is displayed on all-day row in calendar views such as day, week and work week views alone, when the number of appointment count present in a cell exceeds three. Clicking on the text indicator here will not open a popup, but will allow the expand/collapse option for viewing the remaining appointments present in the all-day row.

The following code example shows how to disable the display of such popups while clicking on the more text indicator.

import * as React from 'react';
import { useRef } from 'react';
import { Day, Week, WorkWeek, Month, ScheduleComponent, ViewsDirective, ViewDirective, Inject } from '@syncfusion/ej2-react-schedule';
import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
const App = () => {
  const scheduleObj = useRef(null);
  const ClickButton = () => {
    scheduleObj.current.closeQuickInfoPopup();
  }
  const data = [{
    Id: 1,
    Subject: 'Review Meeting',
    StartTime: new Date(2023, 2, 5, 9, 0, 0),
    EndTime: new Date(2023, 2, 5, 10, 0, 0)
  }];
  const eventSettings = { dataSource: data };

  return (<div>
    <ButtonComponent onClick={ClickButton.bind(this)}>Close QuickInfo Popup</ButtonComponent>
    <ScheduleComponent width='100%' height='550px' selectedDate={new Date(2023, 2, 5)} ref={scheduleObj} currentView='Month' eventSettings={eventSettings}>
      <ViewsDirective>
        <ViewDirective option='Day' />
        <ViewDirective option='Week' />
        <ViewDirective option='WorkWeek' />
        <ViewDirective option='Month' />
      </ViewsDirective>
      <Inject services={[Day, Week, WorkWeek, Month]} />
    </ScheduleComponent>
  </div>);
}
const root = ReactDOM.createRoot(document.getElementById('schedule'));
root.render(<App />);
