Themes for Web Reporting are based on Generic, Generic Compact, Material Design, and Material Design Compact themes. For more information, review the following help topic: Predefined Themes. Due to design considerations, compact themes for web reporting components are the same as the themes without the word “compact” in their names.

The predefined themes and their respective files are listed below. A theme consists of stylesheets that contain a collection of CSS classes.

How to Apply a Predefined Theme

To apply a predefined theme, include the respective CSS files into the page that contains the reporting component. If your project uses bundled resources, add the corresponding entry to the bundleconfig.json file. The following code adds the Orange Light Material theme:

bundleconfig.json

{
"outputFileName": "wwwroot/css/dx.material.orange.light.bundle.css",
"inputFiles": [
    "node_modules/devextreme/dist/css/dx.material.orange.light.css",
    "node_modules/@devexpress/analytics-core/dist/css/dx-analytics.material.orange.light.css"
],
"minify": {
    "enabled": false,
    "adjustRelativePaths": false
}
},

Make sure that the application has access to fonts required for the Material theme. If your application uses Libman, add the following entry to the configuration file:

libman.json

{
  "version": "1.0",
  "defaultProvider": "filesystem",
  "libraries": [

    {
      "library": "node_modules/devextreme/dist/css/icons/",
      "destination": "wwwroot/css/icons",
      "files": [
        "dxiconsmaterial.ttf",
        "dxiconsmaterial.woff",
        "dxiconsmaterial.woff2",
        "dxicons.ttf",
        "dxicons.woff2",
        "dxicons.woff"
      ]
    }
  ]
}
