Create a new Blazor WebAssembly App

Create a Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Syncfusion® Blazor Extension. For detailed instructions, refer to the Blazor WebAssembly App Getting Started documentation.

Run the following command to create a new Blazor WebAssembly App.

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

Alternatively, create a Blazor WebAssembly App using Visual Studio Code via Microsoft Templates, the Syncfusion® Blazor Extension, or the C# Dev Kit extension.

Run the following command to create a new Blazor WebAssembly App.

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

Install the required Blazor packages

Install the Syncfusion.Blazor.RichTextEditor and Syncfusion.Blazor.Themes NuGet packages. All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details.

  1. Go to Tools → NuGet Package Manager → Manage NuGet Packages for Solution.
  2. Search the required NuGet packages (Syncfusion.Blazor.RichTextEditor and Syncfusion.Blazor.Themes) and install them.

Alternatively, you can install the same packages using the Package Manager Console with the following commands.

Install-Package Syncfusion.Blazor.RichTextEditor -Version 34.2.2
Install-Package Syncfusion.Blazor.Themes -Version 34.2.2

Open the terminal and run the following commands.

dotnet add package Syncfusion.Blazor.RichTextEditor -v 34.2.2
dotnet add package Syncfusion.Blazor.Themes -v 34.2.2

Open the command prompt and run the following commands.

dotnet add package Syncfusion.Blazor.RichTextEditor -v 34.2.2
dotnet add package Syncfusion.Blazor.Themes -v 34.2.2

Add import namespaces

After the packages are installed, open the ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.RichTextEditor namespaces.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.RichTextEditor

Register the Blazor service

Open the Program.cs file in Blazor WebAssembly App and register the Blazor service and include the required namespace reference using Syncfusion.Blazor; at the top.

builder.Services.AddSyncfusionBlazor();

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet at the end of the <head> section in the ~wwwroot/index.html file.

<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />

Include the required script references at the end of the <body> section in the ~wwwroot/index.html file to enable Rich Text Editor functionality.

<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

Add Blazor Rich Text Editor component

Open a Razor file located in the ~/Pages/*.razor (for example, Home.razor) and add the Blazor Rich Text Editor component inside the razor file.

@using Syncfusion.Blazor.RichTextEditor

<SfRichTextEditor>
    <p>Rich Text Editor allows you to insert images from an online source as well as from a local computer where you want to insert the image in your content.</p>
    <p><b>Get started with the Quick Toolbar to click on the image</b></p>
    <p>It is possible to add a custom style to the selected image inside the Rich Text Editor through the Quick Toolbar.</p>
</SfRichTextEditor>

Run the application

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. The Blazor Rich Text Editor component will render in your default web browser.

Open the terminal and run the following command.

dotnet run

Open the command prompt and run the following command.

dotnet run
