jQuery/JS Common - Utils - ui - themes

An object that serves as a namespace for the methods that work with DevExtreme CSS Themes.

import ui.themes from "devextreme/ui/themes"

current()

Gets the current theme's name.

Return Value:

String

The current theme's name.

current(themeName)

Sets a theme with a specific name.

Parameters:
themeName:

String

The theme's name.

The theme name passed as a parameter should be the value of the data-theme attribute used within the rel="dx-theme" links to the theme. For instance, if you have links to two of your themes...

HTML
  • <link rel="dx-theme" data-theme="generic.dark" href="css/mytheme-dark.css" data-active="true">
  • <link rel="dx-theme" data-theme="generic.light" href="css/mytheme-light.css" data-active="false">

... you can switch between them as shown in the code below. Note that you should specify a callback function that repaints all UI components after the theme has been loaded using the ready(callback) method.

JavaScript
  • DevExpress.ui.themes.ready(function () {
  • $("#dataGridContainer").dxDataGrid("repaint");
  • // Call other UI components' repaint() method here
  • });
  • DevExpress.ui.themes.current('generic.light');
  • // DevExpress.ui.themes.current('generic.dark');

Refer to the Predefined Themes article for details on the themes that are supplied with DevExtreme.
