The Scheduler works with collections of objects.

Depending on your data source, bind the Scheduler to data as follows. In each case, also specify the UI component's startDateExpr and endDateExpr properties. Optionally, set other properties with the Expr postfix.

Data Array
Assign the array to the dataSource option. View Demo
Read-Only Data in JSON Format
Set the dataSource property to the URL of a JSON file or service that returns JSON data.
OData
Implement an ODataStore.

Web API, PHP, MongoDB
Use one of the following extensions to enable the server to process data according to the protocol DevExtreme UI components use:

Then, use the createStore method to configure access to the server on the client as shown below. This method is part of DevExtreme.AspNet.Data.

Any other data source
Implement a CustomStore. View Demo

Regardless of the data source on the input, the Scheduler always wraps it in the DataSource object. This object allows you to sort, filter, group, and perform other data shaping operations. To get its instance, call the getDataSource() method.

NOTE

Review the following notes about data binding:

If you wrap the store into the DataSource object explicitly, set the paginate property to false to prevent data from partitioning.
Data field names cannot be equal to this and should not contain the following characters: ., :, [, and ].

jQuery

The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Get and Set Properties.

Angular

The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Two-Way Property Binding.

Vue

The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Two-Way Property Binding.

React

The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Controlled Mode.

Specifies the format in which date-time values should be sent to the server.

Type:

Web API Service Demo SignalR Service Demo

Default Value: undefined

Specify this property in the following cases:

The dataSource is empty or not set at design time. The dateSerializationFormat is needed, because the Scheduler cannot detect it automatically without a data source.
You use the createStore method from the DevExtreme.AspNet.Data extension and remote date-time values are specified in UTC. DevExtreme.AspNet.Data requires the dateSerializationFormat to correctly serialize these values.

Use one of the following values to specify the dateSerializationFormat property:

"yyyy-MM-dd" - local date
"yyyy-MM-ddTHH:mm:ss" - local date and time
"yyyy-MM-ddTHH:mm:ssZ" - UTC date and time
"yyyy-MM-ddTHH:mm:ssx" - date and time with a timezone

To group appointments by resources of one kind, for instance to group appointments that use particular rooms in an office, assign an array with a single element to the groups property. To group appointments by several resource kinds, assign an array of elements. Each element will represent a resource by which appointments will be grouped. Each resource will be nested to the resource represented by the previous element in the groups array.

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.

hint

Specifies text for a hint that appears when a user pauses on the UI component.

Type:

Default Value: undefined

indicatorUpdateInterval

Specifies the time interval between when the date-time indicator changes its position, in milliseconds.

Type:

Default Value: 300000

Default Value: undefined

noDataText

Specifies the text or HTML markup displayed by the UI component if the item collection is empty. Available for the Agenda view only.

Type:

Default Value: 'No data to display'

The Scheduler component evaluates the noDataText property's value. This evaluation, however, makes the Scheduler potentially vulnerable to XSS attacks. To guard against these attacks, encode the HTML markup before you assign it to the noDataText property. Refer to the following help topic for more information: Potentially Vulnerable API - noDataText.

onAppointmentAdded

cancel	Boolean \| Promise<Boolean> (jQuery or native)	Allows you to cancel appointment adding. If you pass a Promise to this field, appointment adding is continued or canceled once the Promise has been resolved.
component	Scheduler	The UI component's instance.
element	HTMLElement \| jQuery	The UI component's container. It is an HTML Element or a jQuery Element when you use jQuery.
model	any	Model data. Available only if Knockout is used.

Default Value: null

onAppointmentClick

A function that is executed when an appointment is clicked or tapped.

Type:

Function parameters:

e:

Information about the event.

Object structure:

Name	Type	Description
appointmentData	dxSchedulerAppointment	The initial appointment.
appointmentElement	HTMLElement \| jQuery	The clicked's container. It is an HTML Element or a jQuery Element when you use jQuery.

model	any	Model data. Available only if Knockout is used.
targetedAppointmentData	dxSchedulerAppointment	The clicked appointment.

Default Value: null

In case of recurring appointments or appointments with multiple resources, you may need the data object of the clicked, not the initial, appointment. For this purpose, use the targetedAppointmentData field of the function's parameter. Otherwise, use the appointmentData field.

For example, the data source contains the following data object:

JavaScript

var appointments = [{
    startDate: new Date(2016, 6, 18, 8),
    endDate: new Date(2016, 6, 18, 9),
    ownerId: [1, 2],
    recurrenceRule: "FREQ=DAILY"
}];

This object describes a series of appointments that belong to two owners and repeat every day. If a user clicks an appointment from this series (for example, the second appointment that belongs to the second owner), appointmentData and targetedAppointmentData will then contain the following data objects:

JavaScript

onAppointmentClick: function(e) {
    console.log(e.appointmentData);
    /* {
        startDate: new Date(2016, 6, 18, 8), 
        endDate: new Date(2016, 6, 18, 9),
        ownerId: [1, 2],
        recurrenceRule: "FREQ=DAILY"
    } */

    console.log(e.targetedAppointmentData);
    /* {
        startDate: new Date(2016, 6, 19, 8), 
        endDate: new Date(2016, 6, 19, 9),
        ownerId: 2,
        recurrenceRule: "FREQ=DAILY"
    } */
}

popup	Popup	The instance of the popup that contains the form.

Default Value: null

The Scheduler displays the appointment details form inside a popup. The elements inside the form are the Form and Popup UI components. Use the onAppointmentFormOpening function's form and popup fields and the Form and Popup API to access and customize the corresponding UI component.

The form organizes its items into two groups:

Group name	Description
mainGroup	Contains form fields that define main appointment parameters (for example, subject, and description).
recurrenceGroup	Contains form fields that define appointment recurrence parameters.

The table below lists 'mainGroup' editor names:

Editor Caption on a Form	Editor Name
Subject	'text'. Corresponds to the SchedulerAppointment.text property.
Start Date	'startDate'. Corresponds to the SchedulerAppointment.startDate property.
End Date	'endDate'. Corresponds to the SchedulerAppointment.endDate property.
All Day	'allDay'. Corresponds to the SchedulerAppointment.allDay property.
Description	'description'. Corresponds to the SchedulerAppointment.description property.

You can add a custom item to any group or create an ungrouped item and display it under the groups. If you use the [fieldName]Expr properties to map custom items to data fields, use these property values to access the items on the appointment form.

DevExtreme Scheduler onAppointmentFormOpening

The code below adds a new form item (phone) to the mainGroup and creates an ungrouped item (location). Check the array of form items to ensure that it does not contain an item with the same data field.

The mainGroup consists of two columns. A custom item's colSpan property value is 2. This means that the custom item spans two columns.

            if(e.name === "changedProperty") {
                // handle the property change here
            }
        }
    });
});

Angular

app.component.html

app.component.ts

app.module.ts

<dx-scheduler ...
    (onOptionChanged)="handlePropertyChange($event)"> 
</dx-scheduler>

import { Component } from '@angular/core'; 

@Component({ 
    selector: 'app-root', 
    templateUrl: './app.component.html', 
    styleUrls: ['./app.component.css'] 
}) 

export class AppComponent { 
    // ...
    handlePropertyChange(e) {
        if(e.name === "changedProperty") { 
            // handle the property change here
        }
    }
}

import { BrowserModule } from '@angular/platform-browser'; 
import { NgModule } from '@angular/core'; 
import { AppComponent } from './app.component'; 
import { DxSchedulerModule } from 'devextreme-angular'; 

@NgModule({ 
    declarations: [ 
        AppComponent 
    ], 
    imports: [ 
        BrowserModule, 
        DxSchedulerModule 
    ], 
    providers: [ ], 
    bootstrap: [AppComponent] 
}) 

export class AppModule { }

Vue

React

App.js

import React from 'react';  
import 'devextreme/dist/css/dx.light.css'; 

import Scheduler from 'devextreme-react/scheduler'; 

const handlePropertyChange = (e) => {
    if(e.name === "changedProperty") {
        // handle the property change here
    }
}

export default function App() { 
    return ( 
        <Scheduler ...
            onOptionChanged={handlePropertyChange}
        />        
    ); 
}

recurrenceEditMode

Specifies the edit mode for recurring appointments.

Type:

Default Value: 'dialog'

Accepted Values: 'dialog' | 'occurrence' | 'series'

This property accepts the following values:

"series"
Enables a user to edit only entire appointment series.
"occurrence"
Enables a user to edit only individual appointment instances.
"dialog"
Displays a dialog that suggests a user to choose between editing the entire series or only the individual instance.

The Scheduler handles changes made to an instance and a series differently. If a user edits a recurring appointment instance, two actions are performed on the data objects:

The series' data object is updated. The Scheduler updates the field specified by recurrenceExceptionExpr, thus adding the edited instance to exceptions. The onAppointmentUpdating and onAppointmentUpdated event handlers are executed.
A new data object is created. This object contains the edited instance's data. The onAppointmentAdding and onAppointmentAdded event handlers are executed.

When a user deletes an instance, the Scheduler adds it to series' exceptions by updating the field specified in recurrenceExceptionExpr. Because this is an update, the onAppointmentUpdating and onAppointmentUpdated event handlers are executed instead of onAppointmentDeleting and onAppointmentDeleted.

If a user edits a whole series, only the series data object is updated. When a whole series is deleted, its object is removed.

recurrenceExceptionExpr

Specifies the name of the data source item field that defines exceptions for the current recurring appointment.

Type:

Default Value: 'recurrenceException'

recurrenceRuleExpr

Specifies the name of the data source item field that defines a recurrence rule for generating recurring appointments.

Type:

Default Value: 'recurrenceRule'

remoteFiltering

Specifies whether filtering is performed on the server or client side.

Type:

Web API Service Demo SignalR Service Demo

Default Value: false

NOTE

If you use the CustomStore as a data source and the remoteFiltering property is set to false, the parameter of the load method does not contain the filter field.

resourceCellComponent

An alias for the resourceCellTemplate property specified in React. Accepts a custom component. Refer to Using a Custom Component for more information.

resourceCellRender

An alias for the resourceCellTemplate property specified in React. Accepts a rendering function. Refer to Using a Rendering Function for more information.

resourceCellTemplate

Specifies a custom template for resource headers.

Type:

Template Data:

Resources Demo Grouping by Resources Demo

The current resource header's data.

Default Name: null

resources[]

Specifies an array of resources available in the scheduler.

Selector: Resource

Type:

Array<Object>

Default Value: []

Each element of this array is an object that defines a resource kind - a room, a car or any other resource kind. A resource kind object must have at least the following fields.

dataSource
Specify the available resources of this kind (room1, room2, etc.).
fieldExpr
The name of the appointment object field that specifies a resource of this kind (e.g., "room").

There are more fields that can be specified within a resource kind object. They are listed below. For details on how to define a resource and assign it to scheduler appointments, refer to the Resources article.

rtlEnabled

Switches the UI component to a right-to-left representation.

Type:

DataGrid Demo Navigation UI Demo Editors Demo

Default Value: false

When this property is set to true, the UI component text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.

JavaScript

DevExpress.config({
    rtlEnabled: true
});

scrolling

Configures scrolling.

Selector: Scrolling

Type: dxSchedulerScrolling

Scrolling allows a user to browse data outside the current viewport. Information about the available scrolling modes is in the mode property description.

selectedCellData

The data of the currently selected cells.

Type:

Array<any>

Read-only

Default Value: []

This array contains objects with the following structure:

{
    startDate: Date,
    endDate: Date,

    groups: { // present if grouping is enabled
        resourceKind: "resourceValue" // for example, room: "101"
    }     
}

You can implement the onOptionChanged function to track all user actions that change selection. The following code logs the selectedCellData value in the browser console.

JavaScript

const onOptionChanged = ({ name, value }) => {
    if (name === "selectedCellData") {
        console.log(value);
    }
};

Type:

Template Data:

The data of the current time scale item.

Default Name: null

NOTE

There is no timeCellTemplate in such views as "month", "timelineMonth" and "agenda".

timeZone

Specifies the time zone for the Scheduler's grid. Accepts values from the IANA time zone database.

Type:

Default Value: ''

If no time zone is specified, the grid displays appointments in the client's time zone.

You can also specify the startDateTimeZone and endDateTimeZone properties for individual appointments.

useDropDownViewSwitcher

Specifies whether a user can switch views using tabs or a drop-down menu.

Type:

Default Value: false, true (Android, iOS, Material)

views: [{
        type: 'workWeek',
        name: 'Vertical Grouping',
        groupOrientation: 'vertical',
        cellDuration: 60,
