appointmentTemplate

The template to be used for rendering appointments.

Type: template
Function parameters:
itemData: Object

The appointment object to be rendered.

itemIndex: Number

The index of the appointment to be rendered.

itemElement: jQuery

An HTML element of the appointment to be rendered.

Return Value: String|DOM Node|jQuery

A template name or a template container.

Default Value: 'item'

A binding context of an appointment template is the data source object that corresponds to the currently rendered appointment.

Angular

Use a variable that is declared in the template via the let keyword to access appointment object fields in Angular apps.

HTML
<dx-scheduler ...
    appointmentTemplate="appointmentTemplate">
    <div *dxTemplate="let appointment of 'appointmentTemplate'">
        <div class="appointment-header">{{appointment.text}}</div>
        <div class="appointment-time">{{appointment.startDate}} - {{appointment.endDate}}</div>
    </div>
</dx-scheduler>
AngularJS

In AngularJS apps, if you need to access appointment object fields within a template, use a variable whose name is assigned to the dx-item-alias directive. Add the directive to the widget element to specify an alias to the root object. Without this directive, appointment object fields are beyond reach. To access another binding context within an appointment template, use AngularJS binding variables.

HTML
<div dx-scheduler="{ 
    ...
    appointmentTemplate: 'appointment'
}" dx-item-alias="appItem">
    <div data-options="dxTemplate: {name: 'appointment'}" style="padding: 0;">
        <div class="appointment-header">{{appItem.text}}</div>
        <div class="appointment-time">{{appItem.startDate}} - {{appItem.endDate}}</div>

cellDuration

Specifies cell duration in minutes.

Type: Number
Default Value: 30

crossScrollingEnabled

Specifies whether or not an end-user can scroll the view in both directions at the same time.

Type: Boolean
Default Value: false

This option is useful when displaying Scheduler on narrow screens.

currentDate

Specifies a date displayed on the current scheduler view by default.

Default Value: new Date()

This is the date which is displayed when rendering the widget. Although, an end-user can change the current date by using the Date Navigator.

Show Example:
AngularJS
Knockout
jQuery

currentView

Specifies the view used in the scheduler by default.

Type: String
Default Value: 'day'
Accepted Values: 'day' | 'week' | 'workWeek' | 'month' | 'timelineDay' | 'timelineWeek' | 'timelineWorkWeek' | 'timelineMonth' | 'agenda'

Specify the views to be available in the scheduler's View Switcher for end users in the views array. The default view used by the widget when rendering the scheduler is specified by the currentView option.
For more information on scheduler views, refer to the Views guide.

When using the widget as an ASP.NET MVC Control, specify this option using the SchedulerViewType enum. This enum accepts the following values: Day, Week, WorkWeek, Month, TimelineDay, TimelineWeek, TimelineWorkWeek, TimelineMonth and Agenda.

Show Example:
AngularJS
Knockout
jQuery

dataCellTemplate

The template to be used for rendering table cells.

Type: template
Function parameters:
itemData: Object

The table cell object to be rendered.

itemIndex: Number

The index of the table cell to be rendered.

itemElement: jQuery

An HTML element of the table cell to be rendered.

Return Value: String|DOM Node|jQuery

A template name or a template container.

Default Value: null

The binding context of a cell template is the object that corresponds to the currently rendered table cell.

So, in the Knockout approach, you can bind template elements to the cell object fields. To access another binding context within a template, use Knockout binding variables.

In the AngularJS approach, if you need to access cell object fields within a template, use a variable whose name is assigned to the dx-item-alias directive. Add the directive to the widget element to specify an alias to the root object. Without this directive, the fields of cell object are unavailable. To access another binding context within a table cell template, use Angular binding variables.

NOTE
There is no dataCellTemplate in the agenda view.

dataSource

Specifies the origin of data for the widget.

Default Value: null

This option accepts one of the following.

  • Array of objects
    A simple JavaScript array containing a collection of plain objects.

  • URL
    A URL to JSON data or to a service returning data in JSON format.

  • DataSource or its configuration object
    A DataSource is an object that provides a handy API for data processing. A DataSource is a stateful object, which means that it saves data processing settings and applies them each time data is loaded. All underlying data access logic of a DataSource is isolated in a Store. A Store provides an API for reading and modifying data. Unlike the DataSource, a Store is a stateless object.

To display appointments, a default template can be used. This template is based on the data source fields that are listed in the Default Item Template section of the widget's API. Alternatively, you can implement a custom template.

HTML
TypeScript
<dx-scheduler ...
    [groups]="['priorityId']"
    [resources]="resources"
    resourceCellTemplate="resourceTemplate">
    <div *dxTemplate="let resource of 'resourceTemplate'">
        <img [src]="resource.image">
        <div class="resource-header">{{resource.text}}</div>
    </div>
</dx-scheduler>
export class AppComponent  { 
    // ...
    priorityData = [
        { text: "Low Priority", image: "img1.png", id: 1, color: "#1e90ff" },
        { text: "High Priority", image: "img2.png", id: 2, color: "#ff9747" }
    ];
    resources = [{ 
        field: "priorityId", 
        allowMultiple: false, 
        dataSource: this.priorityData, 
        label: "Priority" 
    }];
}
AngularJS

In the AngularJS apps, if you need to access resource object fields within a template, use a variable whose name is assigned to the dx-item-alias directive. Add the directive to the widget element to specify an alias to the root object. Without this directive, the fields of resource object are unavailable. To access another binding context within a resource template, use Angular binding variables.

HTML
JavaScript
<div dx-scheduler="options" dx-item-alias="item">
    <div data-options="dxTemplate: { name: 'resource' }">
        <img src="{{item.image}}">
        <div class="resource-header">{{item.text}}</div>
    </div>
</div>
var priorityData = [
    { text: "Low Priority", image: "img1.png", id: 1, color: "#1e90ff" },
    { text: "High Priority", image: "img2.png", id: 2, color: "#ff9747" }
];

var DemoApp = angular.module('DemoApp', ['dx']);
DemoApp.controller('DemoController', function DemoController($scope) {
    $scope.options = { 
        // ...
        groups: ["priorityId"],
        resources: [{ 
            field: "priorityId", 
            allowMultiple: false, 
            dataSource: priorityData, 
            label: "Priority" 
        }],
        resourceCellTemplate: 'resource'
    };
});

The option accepts an array of views to be available within the scheduler View Switcher. If you need to customize a view, add a configuration object for it to the array. The configuration options that you can specify are listed further in this documentation section. If a view does not need individual customization, just add its type to the array.

JavaScript
var schedulerOptions = {
    // . . .
    dataSource: schedulerData,
    startDayHour: 9,
    endDayHour: 18,
    views: [
        { type: "day", startDayHour: 7, endDayHour: 22 },
        { type: "workWeek", cellDuration: 60 },
        "week",
        "agenda"
    ]
};

Set a default view by using the currentView option.
For more information on scheduler views, refer to the Views guide.

When using the widget as an ASP.NET MVC Control, specify this option using the SchedulerViewType enum. This enum accepts the following values: Day, Week, WorkWeek, Month, TimelineDay, TimelineWeek, TimelineWorkWeek, TimelineMonth and Agenda.
