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.

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.

dateCellTemplate

Specifies a custom template for day scale items.

Type:

template

Template Data:

Object

The data of the current date scale item.

Default Name: null

The following image shows the difference between Scheduler cell types:

DevExtreme Scheduler - Cell Types

Use this template for date cells only.

The data of this template consists of the following fields:

Field name Description
date Date of the cell.
groups A group object to which date cell belongs.
groupIndex Index of a group to which date cell belongs.
text Text of date cell.

View Demo

dateSerializationFormat

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

Type:

String

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", "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.

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.

String

The UI component's height.

Default Value: undefined

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".

Type:

String

Default Value: undefined

indicatorUpdateInterval

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

Type:

String

Default Value: undefined

maxAppointmentsPerCell

Specifies the limit of full-sized appointments displayed per cell. Applies to all views except "agenda".

Type:

Number

|

String

Default Value: 'auto'
Accepted Values: 'auto' | 'unlimited'

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.

Number

|

String

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:

String

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.

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 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:

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"
    } */
}

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.

JavaScript
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"
    } */
}

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.

recurrenceEditMode

Specifies the edit mode for recurring appointments.

Type:

String

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.

View Demo

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:

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:

String

Default Value: 'recurrenceException'

recurrenceRuleExpr

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

Type:

String

Default Value: 'recurrenceRule'

remoteFiltering

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

Type:

Boolean

Default Value: false

Web API Service Demo SignalR Service Demo

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.

resourceCellTemplate

Specifies a custom template for resource headers.

Type:

template

Template Data:

Object

The current resource header's data.

Default Name: null

resources[]

Specifies an array of resources available in the scheduler.

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. 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.

Type:

Boolean

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
});

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,
    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.

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