Prerequisites

System requirements for ASP.NET Core controls

Create an ASP.NET Core Web Application with Razor pages

You can add the Syncfusion Block Editor to your ASP.NET Core application by installing the Syncfusion ASP.NET Core package. This can be done in two ways described below:

Install Syncfusion ASP.NET Core package in the application

You can add the Syncfusion Block Editor to your ASP.NET Core application by installing the Syncfusion ASP.NET Core package. This can be done in two ways, as mentioned below:

1. Using NuGet Package Manager

Open Visual Studio and navigate to Tools → NuGet Package Manager → Manage NuGet Packages for Solution. Search for Syncfusion.EJ2.AspNet.Core and install it directly.

2. Using Package Manager Console

Run the following command in the Package Manager Console:

Install-Package Syncfusion.EJ2.AspNet.Core -Version 34.1.29

IMPORTANT

Ensure you’re running the command inside Visual Studio’s Package Manager Console (Tools → NuGet Package Manager → Package Manager Console), not in a terminal like CMD or PowerShell.

NOTE

Syncfusion® ASP.NET Core controls are available in nuget.org. Refer to NuGet packages topic to learn more about installing NuGet packages in various OS environments. The Syncfusion.EJ2.AspNet.Core NuGet package has dependencies, Newtonsoft.Json for JSON serialization and Syncfusion.Licensing for validating Syncfusion® license key.

Add Syncfusion® ASP.NET Core Tag Helper

Open ~/Pages/_ViewImports.cshtml file and import the Syncfusion.EJ2 TagHelper.

@addTagHelper *, Syncfusion.EJ2

Add stylesheet and script resources

Here, the theme and script is referred using CDN inside the <head> of ~/Pages/Shared/_Layout.cshtml file as follows,

<head>
    ...
    <!-- Syncfusion ASP.NET Core controls styles -->
    <link rel="stylesheet" href="https://cdn.syncfusion.com/ej2/34.1.29/fluent2.css" />
    <!-- Syncfusion ASP.NET Core controls scripts -->
    <script src="https://cdn.syncfusion.com/ej2/34.1.29/dist/ej2.min.js"></script>
</head>

NOTE

Check out the Themes topic to learn different ways (CDN, NPM package, and CRG) to refer styles in ASP.NET Core application, and to have the expected appearance for Syncfusion® ASP.NET Core controls.

NOTE

Check out the Adding Script Reference topic to learn different approaches for adding script references in your ASP.NET Core application.

Register Syncfusion® Script Manager

Also, register the Script Manager <ejs-script> at the end of <body> in the ASP.NET Core application as follows.

<body>
    ...
    <!-- Syncfusion ASP.NET Core Script Manager -->
    <ejs-scripts></ejs-scripts>
</body>

Add ASP.NET Core Block Editor control

Now, add the Syncfusion® ASP.NET Core Block Editor tag helper to ~/Pages/Index.cshtml page.

@using Syncfusion.EJ2.BlockEditor

<div id='blockeditor-container'>
    <ejs-blockeditor id="block-editor"></ejs-blockeditor>
</div>

<style>
    #blockeditor-container {
        margin: 20px auto;
    }
</style>
public ActionResult Index()
{
    return View();
}

IMPORTANT

When the Block Editor control is rendered, the id attribute must be provided; otherwise, the control will fail to render.

Run the application

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to run the app. Then, the Syncfusion® ASP.NET Core Block Editor control will be rendered in the default web browser.
