Supported Themes

You can apply two types of themes to a Web Dashboard:

Predefined themes
You can find the complete list in the table below. All the listed options are different modifications of the Generic, Generic Compact, and Material Design Compact DevExtreme themes.
Custom themes
You can modify Generic and Generic Compact DevExtreme themes. This topic includes step-by-step instructions on theme customization.

Each theme consists of stylesheets that are applied when you use one of the color constants.

Apply a Built-in Theme

To apply a theme, pass its name as the optional clientUIControlColorScheme parameter to the ExtensionsFactory.GetStyleSheets method.

View code:

    // ...
    new StyleSheet { ExtensionSuite = ExtensionSuite.Dashboard }
// ...

As an alternative, use the ASPxWebClientUIControl.GlobalColorScheme property to specify the theme.

using DevExpress.Web;

    public class HomeController : Controller
        public ActionResult Index()
            ASPxWebClientUIControl.GlobalColorScheme = "carmine";
            return View();

Customize Themes


Customization is available only for Generic and Generic Compact themes.

The DevExpress Dashboard CLI is used with the DevExtreme ThemeBuilder to create a custom theme for the Web Dashboard.

Theme customization involves the following basic steps:

  1. Use the DevExtreme ThemeBuilder tool to customize an existing theme and export the results.
  2. Add Dashboard-specific settings to the generated resource files.
  3. Use the DevExpress Dashboard CLI to convert the customized resource files into a Web Dashboard theme.
  4. Register the new theme in your application.

Create a Custom Theme

  1. Make sure you have Node.js and npm installed on your machine.
  2. Open the ThemeBuilder. Create a custom theme based on Generic themes. For instance, you can use the Light theme as a base and change its accent color from blue (#337ab7) to yellow (#fdb400).
  3. Set the color scheme name (for example, “light-yellow”) and use the Export MetadataDownload Metadata File button to export metadata in a JSON format.
  4. Copy the downloaded JSON file (dx.generic.light-yellow.json) to an empty folder.
  5. Edit dx.generic.light-yellow.json and add the dashboardItems property to override the accent colors at the dashboard level:

        "items": [
                "key": "@base-accent",
                "value": "#fdb400"
        "dashboardItems": [  
                "key": "@dashboard-item-selected-bg", 
                "value": "rgba(#fdb400, 0.2)" 
                "key": "@dashboard-item-hover-bg", 
                "value": "rgba(#fdb400, 0.1)" 
        "baseTheme": "generic.light",
        "outputColorScheme": "light-yellow",
        "makeSwatch": false,
        "version": "23.1.5",
        "widgets": [],
        "removeExternalResources": false

    Refer to the Color Constants section to see a list of available color constants you can use to customize Web Dashboard colors.

  6. In the folder you created in Step 4, execute the command that installs the devexpress-dashboard-cli package and builds the CSS files for your custom JSON file. Use the same version of the devexpress-dashboard-cli package as the version of DevExpress packages that you use in your application:

    npx devexpress-dashboard-cli@23.1.5 build-theme --input-file dx.generic.light-yellow.json

    This generates the following CSS files and their minified versions:

    • dx.light-yellow.css
    • dx-analytics.light-yellow.css
    • dx-dashboard.light-yellow.css
    • dx.light-yellow.min.css
    • dx-analytics.light-yellow.min.css
    • dx-dashboard.light-yellow.min.css


    The devexpress-dashboard-cli package version should match the version of other DevExpress packages used in your application. To check the version for which you generated the CSS files, open the dx-dashboard.<theme-name>.css file and find the version number in the comments.

Apply a Custom Theme

A custom theme’s icons should be in the same folder as the theme’s CSS files. You can find the icons folder in the following directory: C:\Program Files\DevExpress 23.1\Components\Sources\DevExpress.Web.Resources\Css\DevExtreme.

Copy the icons folder to the directory that contains your theme:


To apply a custom theme, do the following:

  1. Create the Content | custom-themes folder in the project and put the generated CSS files in the created folder.

  2. Register the theme in the Global.asax file:

    using DevExpress.Web; 
    using DevExpress.DashboardWeb; 
            protected void Application_Start() {
  3. Apply the custom theme to the Web Dashboard:

        "light-yellow", new StyleSheet { ExtensionType = ExtensionType.Dashboard } 

The image below shows the Web Dashboard with the custom Light Yellow theme:
