Reference themes in ASP.NET Core application

Syncfusion ASP.NET Core themes can be used in your ASP.NET Core application by referencing the style sheet. Refer the ASP.NET Core Styles Sheet inside the <head> element of ~/Pages/Shared/_Layout.cshtml layout page.

Using the below approaches the themes can be referenced in the ASP.NET Core application,

CDN - Used to reference complete css via static web assets.
CRG - Used to generate resources only for the selected (used) components.
Theme Studio - Used to customize and generate themes only for the selected (used) components.
NPM Packages - Used to customize the existing themes and bundle stylesheet’s in an application.
LibMan - Used to downloads popular libraries and frameworks from a file system or a content delivery network (CDN) in an application.

CDN Reference

Instead of using a local resource on your server, you can use a cloud CDN to refer the theme style sheets. CDN Stands for “Content Delivery Network”. A CDN is a group of servers distributed in different locations. While CDN are often used to host websites, they are commonly used to provide other types of downloadable data as well. Examples include software programs, images, videos, and streaming media.

Syncfusion ASP.NET Core Themes are available in the CDN. Make sure that the version in the URLs matches the version of the Syncfusion Essential JS 2 ASP.NET Core Package you are using.

Individual control CDN Reference

The primary goal of individual control CDN is to optimize the loading time and memory of the website/app in the production stage. The order of individual control package loading should be in line with its dependency graph. The CDN of the Dependency Packages should be included manually before the intended individual control package CDN.

NPM Packages

NPM is a node package manager. It is basically used for managing dependencies of various server-side dependencies. You can manage server-side dependencies manually. It is a command-line program for dealing with said repository that aids in package installation, version management, and dependency management. It is an online repository for the publishing of open-source Node.js projects.

You can add the theme for the ASP.NET Core applications through npm packages using the SCSS files by following the below process.

Install Web Compiler to use SCSS files in ASP.NET Core applications.
To install Web Compiler, open Visual Studio and click the Manage Extensions in the toolbar.

Themes-npm-package-extension

Themes-npm-package-web-compiler

Open Command Prompt from the application root directory and run the following command to install the Syncfusion node_modules in this application.

CMD
npm install @syncfusion/ej2

Create a custom.scss file inside ~/wwwroot/css location and provide the variables to override as shown below.

~/custom.scss
$primary: blue !default;
@import 'ej2/fabric.scss';

Right-click the SCSS file and click the Web Compiler to compile the file.

Themes-npm-packages-compile

The compilerconfig.json file is created. Then, provide the location of the compiled CSS file and include a path as shown in the following code snippet.

compilerconfig.json
[
  {
    "outputFile": "wwwroot/css/custom.css",
    "inputFile": "wwwroot/css/custom.scss",
    "useNodeSass": true,
    "options": {
      "includePath": "node_modules/@syncfusion"
    }
  }
]

The SCSS file has been compiled to the CSS file. Then, add this CSS file to the <head> element of the ~/Pages/Shared/_Layout.cshtml page.

~/_Layout.cshtml
<head>
    ...
    <!-- Syncfusion ASP.NET Core controls styles -->
    <link rel="stylesheet" href="~/css/custom.css" />
</head>

Run the application and see the fabric themes from installed npm packages were applied.

Change theme dynamically

In the ASP.NET Core application, the application theme can be changed dynamically by changing its style sheet reference in code.

1.Modify the ~/Pages/Shared/_Layout.cshtml page with the below code to implement a theme change dynamically using the dropdown by its id value in javascript function in the application.

~/_Layout.cshtml
@model IndexModel
<!DOCTYPE html>
<html lang="en">
<head>
    ...
    <!-- Syncfusion ASP.NET Core controls styles -->
    <link id="cssfile" rel="stylesheet" href="https://cdn.syncfusion.com/ej2/27.2.2/bootstrap5.css" />
</head>
<body>
<header>
    ...
    <div>
        <ejs-dropdownlist id="theme" dataSource="@Model.Themes" index="1" change="onThemeChange" placeholder="Themes" floatLabelType="Always">
        <e-dropdownlist-fields text="Text" value="ID"></e-dropdownlist-fields>
        </ejs-dropdownlist>
    </div>
</header>

<script type="text/javascript">
    function onThemeChange(e) {
        document.getElementsByTagName('body')[0].style.display = 'none';
        var themeName = e.value;
        let synclink = document.getElementById('cssfile');
        synclink.href = 'https://cdn.syncfusion.com/ej2/27.2.2/' + themeName + '.css';
        setTimeout(function () { document.getElementsByTagName('body')[0].style.display = 'block'; }, 200);
    }
</script>

2.Add the following code for dropdown data on the ~/Pages/Index.cshtml.cs model page.

~/Index.cshtml.cs
public List<ThemeDetails> Themes = new List<ThemeDetails>() {
    new ThemeDetails(){ ID = "material", Text = "Material" },
    new ThemeDetails(){ ID = "bootstrap", Text = "Bootstrap" },
    new ThemeDetails(){ ID = "fabric", Text = "Fabric" },
    new ThemeDetails(){ ID = "bootstrap4", Text = "Bootstrap 4" },
    new ThemeDetails(){ ID = "tailwind", Text = "TailWind"},
    new ThemeDetails(){ ID = "tailwind-dark", Text = "TailWind Dark" },
    new ThemeDetails(){ ID = "material-dark", Text = "Material Dark" },
    new ThemeDetails(){ ID = "bootstrap-dark", Text = "Bootstrap Dark" },
    new ThemeDetails(){ ID = "fabric-dark", Text = "Fabric Dark" },
    new ThemeDetails(){ ID = "highcontrast", Text = "High Contrast" }
};

public class ThemeDetails
{
    public string ID { get; set; }
    public string Text { get; set; }
}
