Angular Calendar Properties
An object defining configuration properties for the Calendar UI component.
See Also
accessKey
Specifies the shortcut key that sets focus on the UI component.
The value of this property will be passed to the accesskey
attribute of the HTML element that underlies the UI component.
activeStateEnabled
Specifies whether the UI component changes its visual state as a result of user interaction.
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.
See Also
disabled
Specifies whether the UI component responds to user interaction.
disabledDates
Specifies dates that users cannot select.
true if the date should be disabled; otherwise false.
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;
