Vue Box Props

An object defining configuration properties for the Box UI component.

align

Specifies how UI component items are aligned along the main direction.

Type:

Distribution

Default Value: 'start'

crossAlign

Specifies how UI component items are aligned cross-wise.

Selector: cross-align
Default Value: 'start'

dataSource

Binds the UI component to data.

Selector: data-source
Default Value: null

The Box works with collections of string values or objects.

Depending on your data source, bind Box to data as follows. If the data source provides objects, also specify the itemTemplate. You can skip this part if the objects contain fields described in the items section.

  • Data Array
    Assign the array to the dataSource option.

  • 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.

Regardless of the data source on the input, the Box 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:

  • Do not specify the items property if you specified the dataSource, and vice versa.

  • 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.

|

String

|

Function

Number

|

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".

    Refer to the W0017 warning description for information on how you can migrate to viewport units.

hoverStateEnabled

Specifies whether the UI component changes its state when a user pauses on it.

Selector: hover-state-enabled
Type:

Boolean

Default Value: false

itemHoldTimeout

The time period in milliseconds before the onItemHold event is raised.

Selector: item-hold-timeout
Type:

Number

Default Value: 750

items[]

An array of items displayed by the UI component.

Selector: DxItem
Type:

Array<String | dxBoxItem | 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
boxInstance.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.

itemTemplate

Specifies a custom template for items.

Selector: item-template
Type:

template

Template Data:

Object

The item object to be rendered.

Default Name: 'item'
