dataSource
Binds the UI component to data.
The Scheduler works with collections of objects.
Depending on your data source, bind 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 DemoRead-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.
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.
Field names cannot be equal to
this
and should not contain the following characters:.
,:
,[
, and]
.Scheduler does not execute dataSource.sort functions. To implement custom sorting logic, implement columns[].calculateSortValue.

dateSerializationFormat
Specifies the format in which date-time values should be sent to the server.
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"
,"yyyy-MM-ddTHH:mm:ssxx"
,"yyyy-MM-ddTHH:mm:ssxxx"
- date and time with a timezone
This property applies only if the forceIsoDateParsing field is set to true in the global configuration object.

endDateExpr
Specifies the name of the data source item field that defines the ending of an appointment.
endDateTimeZoneExpr
Specifies the name of the data source item field that defines the timezone of the appointment end date.
endDayHour
Specifies the last hour on the time scale. Accepts integer values from 0 to 24.
This property applies to all views at once. To override it for a specific view, set the same property in the view's configuration object.
firstDayOfWeek
Specifies the first day of a week. Does not apply to the agenda view.
This property can accept a value from 0 to 6:
- 0 - Sunday
- 1 - Monday
- 2 - Tuesday
- 3 - Wednesday
- 4 - Thursday
- 5 - Friday
- 6 - Saturday
The value provided by the culture settings is used by default.
focusStateEnabled
Specifies whether the UI component can be focused using keyboard navigation.
groupByDate
If true, appointments are grouped by date first and then by resource; opposite if false. Applies only if appointments are grouped and groupOrientation is "horizontal".
groups
Specifies the resource kinds by which the scheduler's appointments are grouped in a timetable.
This array should contain one or more values that correspond to the fieldExpr values of resource kinds:
jQuery
var resources = [ { fieldExpr: "room", dataSource: roomsDataSource }, { fieldExpr: "teacher", dataSource: teachersDataSource } ]; var schedulerOptions = { dataSource: appointments, resources: resources, groups: ["room", "teacher"] // ... }
Angular
<dx-scheduler [dataSource]="appointments" [resources]="resources" [groups]="['room', 'teacher']"> </dx-scheduler>
import { DxSchedulerModule } from "devextreme-angular"; // ... export class AppComponent { // ... resources = [ { fieldExpr: "room", dataSource: this.roomsDataSource }, { fieldExpr: "teacher", dataSource: this.teachersDataSource } ]; } @NgModule({ imports: [ // ... DxSchedulerModule ], // ... })
Vue
<template> <DxScheduler ... :data-source="appointments" :groups="groups"> <DxResource :data-source="roomsDataSource" field-expr="room" /> <DxResource :data-source="teachersDataSource" field-expr="teacher" /> </DxScheduler> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxScheduler } from 'devextreme-vue/scheduler'; export default { components: { DxScheduler }, data() { return { dataSource: [ ... ], groups: ['room', 'teacher'], roomsDataSource: [ ... ], teachersDataSource: [ ... ] // ... } } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import Scheduler, { Resource } from 'devextreme-react/scheduler'; const App = () => { const appointments = [ ... ]; const roomsDataSource = [ ... ]; const teachersDataSource = [ ... ]; const groups = ['room', 'teacher']; return ( <Scheduler ... dataSource={appointments} groups={groups}> <Resource dataSource={roomsDataSource} fieldExpr="room" /> <Resource dataSource={teachersDataSource} fieldExpr="teacher" /> </Scheduler> ); } export default App;
To group appointments in the agenda view or by one type of resource, for instance, to group appointments that use a particular room in an office, assign an array with a single element to the groups property. To group appointments by several resource types, assign an array of elements. Each element represents a resource by which appointments are grouped. Each resource is nested in the resource represented by the previous element in the groups array.
height
Specifies the UI component's 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"
.
hint
Specifies text for a hint that appears when a user pauses on the UI component.
indicatorUpdateInterval
Specifies the time interval between when the date-time indicator changes its position, in milliseconds.
maxAppointmentsPerCell
Specifies the limit of full-sized appointments displayed per cell. Applies to all views except "agenda".
When you set this property to "auto", appointments shrink to a predefined size that depends on the view type. Appointments that do not fit into the cell are hidden, and the cell displays an overflow indicator. Users can click the indicator to display the hidden appointments in a tooltip. The "unlimited" value shrinks appointments without a limit to fit into a cell.
To specify the maximum number of appointments allowed in a single cell, set the property to Number. Appointments that exceed this number are hidden, and the cell displays an overflow indicator. Users can click the indicator to display the hidden appointments in a tooltip.
noDataText
Specifies the text or HTML markup displayed by the UI component if the item collection is empty. Available for the Agenda view only.
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.
offset
Specifies the minute offset within Scheduler indicating the starting point of a day.
This property moves the interval between startDayHour and endDayHour. The offset is a multiple of 5 and can range from -1440 minutes (-24 hours) to 1440 minutes (24 hours). For instance, if the following is true:
The offset is set to 240.
startDayHour is 0 (default).
endDayHour is 24 (default).
Then, the day starts and ends at 04:00 AM instead of 00:00.
You can combine this property with different values of startDayHour, endDayHour, and cellDuration to get the desired result. For example, the following code snippet uses all these properties, and as a result, the day starts at 4:40 AM and ends at 12:00 PM.
jQuery
$(() => { $('#scheduler').dxScheduler({ // ... offset: -20, startDayHour: 5, endDayHour: 12, cellDuration: 40, }); });
Angular
<dx-scheduler ... [offset]="-20" [startDayHour]="5" [endDayHour]="12" [cellDuration]="40" > </dx-scheduler>
Vue
<template> <DxScheduler ... offset="-20" start-day-hour="5" end-day-hour="12" cell-duration="40" /> </template> <script> // ... </script>
React
// ... export default function App() { return ( <Scheduler ... offset="-20" startDayHour="5" endDayHour="12" cellDuration="40" /> ) }

targetedAppointmentData |
The clicked appointment. |
In case of recurring appointments or appointments with multiple resources, you may need the data object of the clicked appointment, 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:
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:
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" } */ }
Additionally, the targetedAppointmentData field has the displayStartDate and displayEndDate date objects. These objects contain time-zone adjusted dates if you specify the timeZone property. If the latter property is not specified, the date objects mentioned above have the same values as the startDate and endDate objects.
onAppointmentClick: function(e) { console.log(e.targetedAppointmentData); /* { startDate: new Date(2016, 6, 19, 8), endDate: new Date(2016, 6, 19, 9), displayStartDate: new Date(2016, 6, 19, 10), displayEndDate: new Date(2016, 6, 19, 11), ownerId: 2, recurrenceRule: "FREQ=DAILY" } */ }

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.
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.

The following example shows how to subscribe to component property changes:
jQuery
$(function() { $("#schedulerContainer").dxScheduler({ // ... onOptionChanged: function(e) { if(e.name === "changedProperty") { // handle the property change here } } }); });
Angular
<dx-scheduler ... (onOptionChanged)="handlePropertyChange($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
<template> <DxScheduler ... @option-changed="handlePropertyChange" /> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxScheduler from 'devextreme-vue/scheduler'; export default { components: { DxScheduler }, // ... methods: { handlePropertyChange: function(e) { if(e.name === "changedProperty") { // handle the property change here } } } } </script>
React
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.
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.
recurrenceRuleExpr
Specifies the name of the data source item field that defines a recurrence rule for generating recurring appointments.
See Also
remoteFiltering
Specifies whether filtering is performed on the server or client side.
Web API Service Demo SignalR Service Demo
resources[]
Specifies an array of resources available in the scheduler.
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. The Scheduler does not support grouping resources by multiple data fields in the agenda view.
rtlEnabled
Switches the UI component to a right-to-left representation.
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.
DevExpress.config({ rtlEnabled: true });
scrolling
Configures scrolling.
Scrolling allows a user to browse data outside the current viewport. Information about the available scrolling modes is in the mode property description.
See Also
selectedCellData
The data of the currently selected cells.
This array contains objects with the following structure:
{ startDate: Date, endDate: Date, allDay: Boolean, 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.
const onOptionChanged = ({ name, value }) => { if (name === "selectedCellData") { console.log(value); } };

startDateTimeZoneExpr
Specifies the name of the data source item field that defines the timezone of the appointment start date.
startDayHour
Specifies the first hour on the time scale. Accepts integer values from 0 to 24.
This property applies to all views at once. To override it for a specific view, set the same property in the view's configuration object.
tabIndex
Specifies the number of the element when the Tab key is used for navigating.
The value of this property will be passed to the tabindex
attribute of the HTML element that underlies the UI component.
textExpr
Specifies the name of the data source item field that holds the subject of an appointment.
timeCellTemplate
Specifies a custom template for time scale items.
The following image shows the difference between Scheduler cell types:
Use this template for time cells only.
Field name | Description |
---|---|
date |
Date of the cell. |
groups |
A group object to which time cell belongs. |
groupIndex |
Index of a group to which time cell belongs. |
text |
Text of time cell. |

This property accepts an array of strings and objects:
String
A view name. Use a string if the view does not need customization, but should be available in the view switcher.Object
An individual view's configuration. Set the type property to specify the view to customize. Properties set for an individual view override their corresponding component configuration properties.JavaScriptviews: [{ type: 'workWeek', name: 'Vertical Grouping', groupOrientation: 'vertical', cellDuration: 60, intervalCount: 2, }, { type: 'workWeek', name: 'Horizontal Grouping', groupOrientation: 'horizontal', cellDuration: 30, intervalCount: 2, }, 'agenda' ]
For more information about how to customize an individual view, refer to the following topic: Customize Individual Views.
To specify the default view, use the currentView property.
width
Specifies the UI component's width.
This property accepts a value of one of the following types:
Number
The width in pixels.String
A CSS-accepted measurement of width. For example,"55px"
