This section explains how to include the Blazor Image Editor component in a Blazor Web App using Visual Studio, Visual Studio Code, and the .NET CLI.

To get started quickly with the Blazor Image Editor component, refer to this video or the GitHub sample:

Prerequisites

Create a new Blazor Web App in Visual Studio

Create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion® Blazor Extension. For detailed instructions, refer to this Blazor Web App Getting Started documentation.

Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Web App.

Create Blazor Web App

Install Syncfusion® Blazor ImageEditor and Themes NuGet in the Blazor Web App

To add the Blazor Image Editor component, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), then search for and install Syncfusion.Blazor.ImageEditor and Syncfusion.Blazor.Themes.

If using the WebAssembly or Auto render modes in the Blazor Web App, install Syncfusion® Blazor component NuGet packages in the client project.

Alternatively, run the following commands in the Package Manager Console to achieve the same.

Install-Package Syncfusion.Blazor.ImageEditor -Version 32.1.19
Install-Package Syncfusion.Blazor.Themes -Version 32.1.19

NOTE

Syncfusion® Blazor components are available in nuget.org. Refer to the NuGet packages topic for the available NuGet packages list with component details.

Prerequisites

Create a new Blazor Web App in Visual Studio Code

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

Configure the appropriate interactive render mode and interactivity location when setting up a Blazor Web App. For detailed information, refer to the interactive render mode documentation.

For example, to create a Blazor Web App with the Auto interactive render mode, use the following commands:

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

Install Syncfusion® Blazor ImageEditor and Themes NuGet in the App

If using the WebAssembly or Auto render modes in the Blazor Web App, install Syncfusion® Blazor component NuGet packages in the client project.

  • Press Ctrl+` to open the integrated terminal in Visual Studio Code.
  • Ensure the current directory is the project root where the .csproj file is located.
  • Run the following commands to install Syncfusion.Blazor.ImageEditor and Syncfusion.Blazor.Themes and ensure all dependencies are restored.
dotnet add package Syncfusion.Blazor.ImageEditor -v 32.1.19
dotnet add package Syncfusion.Blazor.Themes -v 32.1.19
dotnet restore

NOTE

Syncfusion® Blazor components are available in nuget.org. Refer to the NuGet packages topic for the available NuGet packages list with component details.

Prerequisites

Install the latest version of .NET SDK. If you previously installed the SDK, you can determine the installed version by executing the following command in a command prompt (Windows) or terminal (macOS) or command shell (Linux).

dotnet --version

Create a Blazor Web App using .NET CLI

Run the following command to create a new Blazor Web App in a command prompt (Windows) or terminal (macOS) or command shell (Linux). For detailed instructions, refer to this Blazor Web App Getting Started documentation.

Configure the appropriate interactive render mode and interactivity location when setting up a Blazor Web Application. For detailed information, refer to the interactive render mode documentation.

For example, to create a Blazor Web App with the Auto interactive render mode, use the following commands:

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

This command creates a new Blazor Web App and places it in a new directory called BlazorApp inside your current location. See the Create a Blazor App and dotnet new CLI command topics for more details.

Install Syncfusion® Blazor ImageEditor and Themes NuGet in the App

Here’s an example of how to add Blazor Image Editor component in the application using the following command in the command prompt (Windows) or terminal (Linux and macOS) to install a Syncfusion.Blazor.ImageEditor and Syncfusion.Blazor.Themes NuGet package. See Install and manage packages using the dotnet CLI topics for more details.

If using the WebAssembly or Auto render modes in the Blazor Web App, install Syncfusion® Blazor component NuGet packages in the client project.

dotnet add package Syncfusion.Blazor.ImageEditor --version 32.1.19
dotnet add package Syncfusion.Blazor.Themes --version 32.1.19
dotnet restore

NOTE

Syncfusion® Blazor components are available in nuget.org. Refer to the NuGet packages topic for the available NuGet packages list with component details.

Add Import Namespaces

Open the ~/_Imports.razor file from the client project and import the Syncfusion.Blazor and Syncfusion.Blazor.ImageEditor namespaces.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.ImageEditor

Register Syncfusion® Blazor Service

Register the Syncfusion® Blazor Service in the ~/Program.cs file of the Blazor Web App.

If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion® Blazor service in the ~/Program.cs files of the main server project and associated .Client project.

...
...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents()
    .AddInteractiveWebAssemblyComponents();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....
...
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.Services.AddSyncfusionBlazor();

await builder.Build().RunAsync();

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>
....
<body>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>

NOTE

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

Add Syncfusion® Blazor Image Editor component

Add the Syncfusion® Blazor Image Editor component to a Razor page located under the Pages folder (e.g., Pages/Home.razor) in either the Server or Client project. If an interactivity location as Per page/component in the web app, define a render mode at top of the component, as follows:

Interactivity location RenderMode Code
Per page/component Auto @rendermode InteractiveAuto
  WebAssembly @rendermode InteractiveWebAssembly
  None —

NOTE

If the Interactivity Location is set to Global and the Render Mode is set to Auto, WebAssembly, the render mode is configured in the App.razor file by default.

@* desired render mode define here *@
@rendermode InteractiveAuto
<SfImageEditor Height="500"></SfImageEditor>
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This renders the Syncfusion® Blazor Image Editor component in the default web browser.
