JavaScript/jQuery Calendar Options
See Also
accessKey
The value of this property will be passed to the accesskey
attribute of the HTML element that underlies the UI component.
activeStateEnabled
The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.
Use this property when you display the component on a platform whose guidelines include the active state change for UI components.
dateSerializationFormat
Specifies the date-time value serialization format. Use it only if you do not specify the value at design time.
Without a value, the UI component cannot detect its format. In this case, specify the dateSerializationFormat property that supports the following formats:
"yyyy-MM-dd"
- a local date"yyyy-MM-ddTHH:mm:ss"
- local date and time"yyyy-MM-ddTHH:mm:ssZ"
- the UTC date and time"yyyy-MM-ddTHH:mm:ssx"
- date and time with a timezone
This property applies only if the forceIsoDateParsing field is set to true in the global configuration object.

disabledDates
This property accepts an array of dates:
jQuery
$(function() { $("#calendarContainer").dxCalendar({ // ... disabledDates: [ new Date("07/1/2017"), new Date("07/2/2017"), new Date("07/3/2017") ] }); });
Angular
<dx-calendar ... [disabledDates]="disabledDates"> </dx-calendar>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { disabledDates: Date[] = [ new Date("07/1/2017"), new Date("07/2/2017"), new Date("07/3/2017") ]; }
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxCalendarModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxCalendarModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxCalendar ... :disabled-dates="disabledDates" /> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxCalendar from 'devextreme-vue/calendar'; export default { components: { DxCalendar }, data() { return { disabledDates: [ new Date("07/1/2017"), new Date("07/2/2017"), new Date("07/3/2017") ] } } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import Calendar from 'devextreme-react/calendar'; class App extends React.Component { constructor() { this.disabledDates = [ new Date("07/1/2017"), new Date("07/2/2017"), new Date("07/3/2017") ]; } render() { return ( <Calendar ... disabledDates={this.disabledDates} /> ); } } export default App;
Alternatively, pass a function to disabledDates. This function should define the rules that determine whether the checked date is disabled. A separate set of rules should target every view individually.
jQuery
$(function() { $("#calendarContainer").dxCalendar({ // ... disabledDates: function(args) { const dayOfWeek = args.date.getDay(); const month = args.date.getMonth(); const isWeekend = args.view === "month" && (dayOfWeek === 0 || dayOfWeek === 6 ); const isMarch = (args.view === "year" || args.view === "month") && month === 2; return isWeekend || isMarch; } }); });
Angular
<dx-calendar ... [disabledDates]="disableDates"> </dx-calendar>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { disableDates(args) { const dayOfWeek = args.date.getDay(); const month = args.date.getMonth(); const isWeekend = args.view === "month" && (dayOfWeek === 0 || dayOfWeek === 6 ); const isMarch = (args.view === "year" || args.view === "month") && month === 2; return isWeekend || isMarch; } }
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxCalendarModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxCalendarModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxCalendar ... :disabled-dates="disableDates" /> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxCalendar from 'devextreme-vue/calendar'; export default { components: { DxCalendar }, methods: { disableDates(args) { const dayOfWeek = args.date.getDay(); const month = args.date.getMonth(); const isWeekend = args.view === "month" && (dayOfWeek === 0 || dayOfWeek === 6 ); const isMarch = (args.view === "year" || args.view === "month") && month === 2; return isWeekend || isMarch; } } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import Calendar from 'devextreme-react/calendar'; class App extends React.Component { disableDates(args) { const dayOfWeek = args.date.getDay(); const month = args.date.getMonth(); const isWeekend = args.view === "month" && (dayOfWeek === 0 || dayOfWeek === 6 ); const isMarch = (args.view === "year" || args.view === "month") && month === 2; return isWeekend || isMarch; } render() { return ( <Calendar ... disabledDates={this.disableDates} /> ); } } export default App;

elementAttr
Specifies the global attributes to be attached to the UI component's container element.
jQuery
$(function(){ $("#calendarContainer").dxCalendar({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-calendar ... [elementAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-calendar>
import { DxCalendarModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxCalendarModule ], // ... })
Vue
<template> <DxCalendar ... :element-attr="calendarAttributes"> </DxCalendar> </template> <script> import DxCalendar from 'devextreme-vue/calendar'; export default { components: { DxCalendar }, data() { return { calendarAttributes: { id: 'elementId', class: 'class-name' } } } } </script>
React
import React from 'react'; import Calendar from 'devextreme-react/calendar'; class App extends React.Component { calendarAttributes = { id: 'elementId', class: 'class-name' } render() { return ( <Calendar ... elementAttr={this.calendarAttributes}> </Calendar> ); } } export default App;
height
This property accepts a value of one of the following types:
Number
The height in pixels.String
A CSS-accepted measurement of height. For example,"55px"
,"20vh"
,"80%"
,"inherit"
.Function (deprecated since v21.2)
Refer to the W0017 warning description for information on how you can migrate to viewport units.
The UI component's minimum height depends on the current theme. If the height property value is less than the minimum height, the UI component height is set to the minimum value, ignoring the specified value. Below is a list of minimum calendar sizes depending on the current theme.
