React Calendar Overview

The Ignite UI for React Calendar component is lightweight and easy to configure. It is used for showing dates and weekdays. It is also the best way for providing monthly or yearly views to end-users. The Ignite UI for React Calendar control lets you restrict the minimum and maximum date ranges that people can navigate through.

The Ignite UI for Ignite UI for React Calendar provides an easy and intuitive way for displaying date information. It packs different features like single or multiple date selection modes, highlight and select date range, keyboard navigation, enabling week numbers, size and spacing options, and more.

React Calendar Example

The following React IgrCalendar component example shows a basic calendar with a single day selection mode. See how it works or inspect the code behind.

How To Create a Calendar in React with Ignite UI

First, you need to the install the corresponding Ignite UI for React npm package by running the following command:

npm install igniteui-react

You will then need to import the Ignite UI for React IgrCalendar and its necessary CSS, like so:

import { IgrCalendar } from 'igniteui-react';
import 'igniteui-webcomponents/themes/light/bootstrap.css';

For a complete introduction to the Ignite UI for React, read the Getting Started topic.

The simplest way to start using the Ignite UI for React IgrCalendar is as follows:

<IgrCalendar />

Selection Modes

Users can choose from three different selection modes - single selection, multiple selection or range selection. By default, the Ignite UI for React IgrCalendar is using single selection mode but you can change it by setting the selection property as shown in this example.

<IgrCalendar selection="multiple" />

Range Selection

Following the same approach, we can switch selection to range mode:

<IgrCalendar selection="range" />

Active View and Date

The Ignite UI for React Calendar component allows you to switch between three different views: days, months and years. The activeView property of the component reflects the current view. By default, the Calendar displays the current date when loaded initially. You could modify this by setting the activeDate property. The activeDate property also reflects the changes of the currently visible date made by the end user.

Week numbers

You can use the showWeekNumbers property to show the week numbers of the Calendar component. You can do this by using its corresponding boolean attribute show-week-numbers like this:

<IgrCalendar showWeekNumbers={true} />

The following demo illustrates a Calendar with enabled week numbers:

Multiple Months

Using the visibleMonths property, you can display more than one month when the Calendar is in days view. When multiple months are displayed, you can configure whether you want to stack them vertically or horizontally by using the orientation property. By default, the orientation property is set to horizontal.

The Calendar displays leading and trailing dates from the previous and the next months. You could hide these dates by setting the hideOutsideDays property to true or using its corresponding boolean attribute hideOutsideDays.

<IgrCalendar visibleMonths={2} hideOutsideDays={true} />

The following sample demonstrates the multiple months configuration:

Size

You could control the size and spacing of the calendar inner elements using the --ig-size CSS variable. The default size of the component is large.

Events

The Calendar component emits the Change event when the selected dates are changed by the end user. You can subscribe to the event like this:

<IgrCalendar onChange={this.onCalendarChange} />

public onCalendarChange(e: IgrComponentDataValueChangedEventArgs) {

}

If you traverse the page using the TAB key you should keep in mind that based on W3 accessability recommendations the IgrCalendar introduces the following tab stops:

Month selection button
Year selection button
Previous button
Next button
Active date element

When a day/month/year in the IgrCalendar component is focused, use:

PAGE UP key to move to the previous month/year/years page.
PAGE DOWN key to move to the next month/year/years page.
HOME key to focus the first day of the current month/first month in view/first year in view.
END key to focus the last day of the current month/last month in view/last year in view.
Arrow keys to navigate through the days/months/years. Navigating before the first item and after the last item will switch the view to the next/previous month/year/years page.

When a day inside the days view is focused, use:

SHIFT + PAGE UP keys to move to the previous year.
SHIFT + PAGE DOWN keys to move to the next year.
SPACE or ENTER key to select the currently focused day.

When a month inside the months view is focused, use:

SPACE or ENTER key to change the activeDate to the currently focused month and switch to days view.

When an year inside the years view is focused, use:

SPACE or ENTER key to change the activeDate to the currently focused year and switch to months view.

When the previous or the next buttons (in the subheader) are focused, use:

SPACE or ENTER key to switch to the previous/next month/year/years page.

When the month button (in the subheader) is focused, use:

SPACE or ENTER key to switch to months view.

When the year button (in the subheader) is focused, use:

SPACE or ENTER key to switch to years view.
