Box

A container widget used to arrange inner elements.

Included in: dx.phonejs.js, dx.webappjs.js, dx.all.js

The widget can arrange inner elements horizontally or vertically depending on the direction option value and align the elements according to the align and crossAlign option values.

You can create a widget using one of the following approaches.

  • jQuery
    Use the dxBox jQuery plug-in.

    HTML
    <div id="box">
        <div id="item1" data-options="dxItem:{ ratio: 1, baseSize: 10}">
            . . .
        </div>
        <div id="item2" data-options="dxItem:{ ratio: 3, baseSize: 40}">
            . . .
        </div>
        <div id="item3" data-options="dxItem:{ ratio: 2, baseSize: 20}">
            . . .
        </div>
    </div>
    JavaScript
    $("#box").dxBox({
        direction: 'row',
        height: '70%',
        width: '90%'
    });
  • Knockout
    Add a div element and apply the dxBox binding to this element.

    HTML
    <div data-bind="dxBox: {
        direction: 'row',
        height: '70%',
        width: '90%'
    }">
        <div id="item1" data-options="dxItem:{ ratio: 1, baseSize: 10}">
            . . .
        </div>
        <div id="item2" data-options="dxItem:{ ratio: 3, baseSize: 40}">
            . . .
        </div>
        <div id="item3" data-options="dxItem:{ ratio: 2, baseSize: 20}">
            . . .
        </div>
    </div>
  • Angular
    Add a div element and apply the dx-box directive to this element.

    HTML
    <div dx-box="{
        direction: 'row',
        height: '70%',
        width: '90%'
    }">
        <div id="item1" data-options="dxItem:{ ratio: 1, baseSize: 10}">
            . . .
        </div>
        <div id="item2" data-options="dxItem:{ ratio: 3, baseSize: 40}">
            . . .
        </div>
        <div id="item3" data-options="dxItem:{ ratio: 2, baseSize: 20}">
            . . .
        </div>
    </div>

Note that DevExtreme widgets require you to link the jQuery and Globalize libraries to your application. If you use the Knockout or Angular approach, the Knockout or Angular library is also required.
