React MultiView Props

An object defining configuration options for the MultiView widget.

accessKey

Specifies the shortcut key that sets focus on the widget.

Type:

String

Default Value: null

The value of this option will be passed to the accesskey attribute of the HTML element that underlies the widget.

activeStateEnabled

Specifies whether or not the widget changes its state when interacting with a user.

Type:

Boolean

Default Value: false

This option is used when the widget is displayed on a platform whose guidelines include the active state change for widgets.

animationEnabled

Specifies whether or not to animate the displayed item change.

Type:

Boolean

Default Value: true

dataSource

A data source used to fetch data to be displayed by 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.

NOTE
Data field names should not contain the following characters: ., ,, :, [, and ]. Their presence may cause issues in the widget's operation.

If the data source is specified using the dataSource option, use the items option only for reading. Updating data items using the items option may cause unexpected results.

To display widget items, 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.

deferRendering

Specifies whether to render the view's content when it is displayed. If false, the content is rendered immediately.

Type:

    .ElementAttr("class", "class-name")
    // ===== or =====
    .ElementAttr(new {
        @id = "elementId",
        @class = "class-name"
    })
    // ===== or =====
    .ElementAttr(new Dictionary<string, object>() {
        { "id", "elementId" },
        { "class", "class-name" }
    })
