dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp

dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp
cd BlazorWebApp.Client

NOTE

Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Web App. For detailed information, refer to the interactive render mode documentation.

Install Syncfusion® Blazor packages

Install the following NuGet packages in your project:

You can install these packages using different methods as shown below:

  1. In Visual Studio Navigate to:

    Tools → NuGet Package Manager → Manage NuGet Packages for Solution

  2. Search for the required packages.
  3. Select the package and click Install.

  1. In Visual Studio Navigate to:

    Tools → NuGet Package Manager → Package Manager Console

  2. Run the following commands:

Install-Package Syncfusion.Blazor.RichTextEditor -Version 33.2.3
Install-Package Syncfusion.Blazor.Themes -Version 33.2.3
  1. Open your project.
  2. Open the terminal:
    • In Visual Studio Code: use the integrated terminal (Ctrl + `)
    • Or use any system terminal for CLI
  3. Run the following commands:
dotnet add package Syncfusion.Blazor.RichTextEditor --version 33.2.3
dotnet add package Syncfusion.Blazor.Themes --version 33.2.3

If using the WebAssembly or Auto render modes in the Blazor Web App, install these packages in the client project.

NOTE

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

Add import namespaces

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

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

Register Syncfusion® Blazor service

Register the Syncfusion Blazor service in the Program.cs file of your Blazor Web App.

....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....

NOTE

If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion® Blazor service in Program.cs files of both the server and client projects in your Blazor Web App.

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet and script references in the ~/Components/App.razor file.

<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
....
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

NOTE

Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Add Syncfusion® Blazor Rich Text Editor component

Add the Syncfusion Blazor Rich Text Editor component in the ~/Components/Pages/*.razor file. If the interactivity location is set to Per page/component in the Web App, define a render mode at the top of the ~/Pages/*.razor file. (For example, InteractiveServer, InteractiveWebAssembly or InteractiveAuto).

NOTE

If the Interactivity Location is set to Global with Auto or WebAssembly, the render mode is automatically configured in the App.razor file by default.

@* desired render mode define here *@
@rendermode InteractiveAuto
@using Syncfusion.Blazor.RichTextEditor

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

To launch the application, press Ctrl+F5 in Visual Studio, run dotnet run from the CLI or integrated terminal in VS Code, or use the Run command in your preferred IDE to render the Syncfusion® Blazor RichTextEditor component in the default web browser.

NOTE

When using the .NET CLI or Visual Studio Code, ensure that you run the application from the server (host) project directory, not from the .Client project. The client project does not run independently and is hosted by the server application.
