Blazor RichTextEditor Component in WebAssembly App using Visual Studio
10 Feb 20235 minutes to read
This article provides a step-by-step instructions for building Blazor WebAssembly App with Blazor RichTextEditor component using Visual Studio.
Prerequisites
Create a Blazor WebAssembly App in Visual Studio
You can create Blazor WebAssembly App using Visual Studio in one of the following ways,
Install Syncfusion Blazor RichTextEditor NuGet in the App
Syncfusion Blazor components are available in nuget.org. To use Syncfusion Blazor components in the application, add reference to the corresponding NuGet. Refer to NuGet packages topic for available NuGet packages list with component details.
To add Blazor RichTextEditor component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.Blazor.RichTextEditor and then install it.
Register Syncfusion Blazor Service
Open ~/_Imports.razor file and import the Syncfusion.Blazor namespace.
@using Syncfusion.Blazor
Now, Open ~/Program.cs file and register the Syncfusion Blazor Service in the client web app. Here, Syncfusion Blazor Service is registered by setting IgnoreScriptIsolation property as true
to load the scripts externally in the next steps.
NOTE
From 2022 Vol-1 (20.1) version, the default value of
IgnoreScriptIsolation
is changed totrue
. It is not necessary to set theIgnoreScriptIsolation
property to refer scripts externally, since the default value has already been changed to true, and this property is obsolete.
using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Syncfusion.Blazor;
var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");
builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
builder.Services.AddSyncfusionBlazor();
await builder.Build().RunAsync();
....
using Syncfusion.Blazor;
namespace BlazorApplication
{
public class Program
{
public static async Task Main(string[] args)
{
....
builder.Services.AddSyncfusionBlazor();
await builder.Build().RunAsync();
}
}
}
Add Style Sheet
Checkout the Blazor Themes topic to learn different ways (Static Web Assets, CDN and CRG) to refer themes in Blazor application, and to have the expected appearance for Syncfusion Blazor components. Here, the theme is referred using Static Web Assets.
To add theme to the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.Blazor.Themes and then install it. Then, the theme style sheet from NuGet can be referred inside the <head>
of wwwroot/index.html file in client web app.
<head>
...
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>
Add Script Reference
Checkout Adding Script Reference topic to learn different ways to add script reference in Blazor Application. In this getting started walk-through, the required scripts are referred using Static Web Assets externally inside the <head>
of wwwroot/index.html file in client web app.
<head>
...
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
<script src="https://cdn.syncfusion.com/blazor/19.4.38/syncfusion-blazor.min.js" type="text/javascript"></script>
</head>
NOTE
Syncfusion recommends to reference scripts using Static Web Assets, CDN and CRG by disabling JavaScript isolation for better loading performance of the Blazor application. Generate scripts and theme assets using CRG by selecting the components you were using in the application.
Add Blazor RichTextEditor component
- Open ~/_Imports.razor file or any other page under the
~/Pages
folder where the component is to be added and import the Syncfusion.Blazor.RichTextEditor namespace.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.RichTextEditor
- Now, add the Syncfusion RichTextEditor component in razor file. Here, the RichTextEditor component is added in the ~/Pages/Index.razor file under the ~/Pages folder.
<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>
- Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to run the app. Then, the Syncfusion Blazor RichTextEditor component will be rendered in the default web browser.
