Angular Toolbar - items

An array of items displayed by the UI component.

Selector: dxi-item
Type:

Array<String | dxToolbarItem | any>

Raised Events: onOptionChanged

The items array can contain:

  • Strings
  • Objects with fields described in this section
  • Objects with any other fields. In this case, specify the itemTemplate.

If you need to update the UI component items, reassign the entire items array as shown in the following example:

JavaScript
toolbarInstance.option('items', newItems);

As an alternative to items, you can use the dataSource property. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.

NOTE
Do not use the items property if you use dataSource, and vice versa.

cssClass

Specifies a CSS class to be applied to the item.

Type:

String

| undefined
Default Value: undefined

disabled

Specifies whether the UI component item responds to user interaction.

Type:

Boolean

Default Value: false

html

Specifies the HTML markup to be inserted into the item element.

Type:

String

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

You can use the text property as a safe alternative.

locateInMenu

Specifies when to display an item in the toolbar's overflow menu.

Type:

LocateInMenuMode

Default Value: 'never'

location

Specifies a location for the item on the toolbar.

Type:

ToolbarItemLocation

Default Value: 'center'

Whatever template you use for UI component items (default or a custom) will be located according to the value specified for the location field in the item data source object.

menuItemTemplate

Specifies a template that should be used to render a menu item.

Type:

template

  • Assign a string containing the name of the required template.
  • Assign a jQuery object of the template's container.
  • Assign a DOM Node of the template's container.
  • Assign a function that returns the jQuery object or a DOM Node of the template's container.

options

Configures the DevExtreme UI component used as a toolbar item.

Type: any
jQuery
$('#toolbar').dxToolbar({
    items: [{
        // ...
        widget: 'dxCheckBox',
        options: {
            text: 'Show IDs'

});
Angular

options should contain the properties of the DevExtreme UI component specified in the widget property. Because of this dependency, options cannot be typed and are not implemented as nested configuration components. Specify options with an object.

app.component.html
app.module.ts
<dx-toolbar ... >
    <dxi-item
        widget="dxCheckBox"
        [options]="{ text: 'Show IDs' }">

Vue

options should contain the properties of the DevExtreme UI component specified in the widget property. Because of this dependency, options cannot be typed and are not implemented as nested configuration components. Specify options with an object. We recommend that you declare the object outside the configuration component to prevent possible issues caused by unnecessary re-rendering.

App.vue
<template>

        <DxItem ...
            widget="dxCheckBox"
            :options="checkBoxOptions"

    },
    data() {
