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(themeName)
Parameters:
themeName:
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.mytheme-dark" href="css/mytheme-dark.css" data-active="true"> <link rel="dx-theme" data-theme="generic.mytheme-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 widgets after the theme has been loaded using the ready(callback) method.
jQuery
JavaScript
DevExpress.ui.themes.ready(function () {
$("#dataGridContainer").dxDataGrid("repaint");
// Call other widgets' repaint() method here

this.dataGrid.instance.repaint();
this.button.instance.repaint();
