Angular TileView Properties

An object defining configuration options for the TileView 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

A Boolean value specifying whether or not the widget changes its state when interacting with a user.

Type:

Boolean

Default Value: true

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

baseItemHeight

Specifies the height of the base tile view item.

Type:

Number

Default Value: 100

The actual item height equals the heightRatio field value of an item multiplied by the value of this option.

baseItemWidth

Specifies the width of the base tile view item.

Type:

Number

Default Value: 100

The actual item width equals the widthRatio value of an item multiplied by the value of this option.

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.

direction

Specifies whether tiles are placed horizontally or vertically.

Type:

String

Default Value: 'horizontal'
Accepted Values: 'horizontal' | 'vertical'

When using the widget as an ASP.NET MVC Control, specify this option using the Orientation enum. This enum accepts the following values: Horizontal and Vertical.

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