Manual refresh in React Schedule component

30 Aug 202324 minutes to read

Refresh Template

In Scheduler, we can able to refresh the elements of the template alone instead of the entire scheduler by using the refreshTemplates public method. We can provide an additional option to refresh specific templates alone or all templates together by using this method. The following template names are accepted as an argument to refresh it specifically.

  • eventTemplate
  • dateHeaderTemplate
  • resourceHeaderTemplate
  • quickInfoTemplates
  • editorTemplate
  • tooltipTemplate
  • headerTooltipTemplate

In the following code example, you can see how to use the refreshTemplates method to refresh multiple templates. Here, we have added the following scheduler templates such as cellTemplate, dateHeaderTemplate, eventTemplate and resourceHeaderTemplate

Refresh Layout

In Scheduler, we can able to refresh the layout manually without re-render the DOM element by using the refreshLayout public method. The following example code explains to know how to use the refreshLayout method.

import { useRef } from 'react';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { ScheduleComponent, Day, Week, WorkWeek, Month, Inject, ViewsDirective, ViewDirective } from '@syncfusion/ej2-react-schedule';
import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
const App = () => {
  const scheduleObj = useRef(null);
  const scheduleData = [{
    Id: 1,
    Subject: 'Testing',
    StartTime: new Date(2021, 10, 16, 10, 0),
    EndTime: new Date(2021, 10, 16, 12, 0),
    IsAllDay: false
  }, {
    Id: 2,
    Subject: 'Vacation',
    StartTime: new Date(2021, 10, 18, 10, 0),
    EndTime: new Date(2021, 10, 18, 12, 0),
    IsAllDay: false
  }];
  const eventSettings = { dataSource: scheduleData };

  const onRefreshLayout = () => {
    scheduleObj.current.refreshLayout();
  }
  return (<div>
    <ButtonComponent onClick={onRefreshLayout}>Refresh Layout</ButtonComponent> <ScheduleComponent ref={scheduleObj} width='100%' height='550px' selectedDate={new Date(2021, 10, 15)} 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 />);
