Getting Started with Blazor WebAssembly Standalone App

15 Apr 20265 minutes to read

This article provides step-by-step instructions for building a Blazor WebAssembly App with the Syncfusion® Blazor DataGrid component using Visual Studio, Visual Studio Code, and the .NET CLI.

Using Playground

Blazor Playground allows interaction with Syncfusion Blazor components directly in a web browser without needing to install any NuGet packages. By default, the Syncfusion.Blazor package is included.

Using Syncfusion® Blazor Templates

You can create a Blazor WebAssembly Standalone App using Syncfusion® Blazor Templates in both Visual Studio and Visual Studio Code.

Manually creating a project

This section provides a brief guide on how to manually create a Blazor WebAssembly App.

Prerequisites

Create a new Blazor WebAssembly App (Standalone) in Visual Studio

You can create a Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Syncfusion® Blazor extension.

Prerequisites

Create a Blazor WebAssembly App in Visual Studio Code

You can create a Blazor WebAssembly App using Visual Studio Code via the Microsoft Templates or the Syncfusion® Blazor extension.

Alternatively, create a WebAssembly application by using the following commands in the integrated terminal (Ctrl+`).

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

Prerequisites

Install the latest version of .NET SDK. If the .NET SDK is already installed, determine the installed version by running the following command in a command prompt (Windows), terminal (macOS), or command shell (Linux).

dotnet --version

Create a Blazor WebAssembly App using .NET CLI

Run the following command to create a new Blazor WebAssembly App in a command prompt (Windows) or terminal (macOS) or command shell (Linux).

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

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

Install Syncfusion® Blazor packages

Install Syncfusion.Blazor.Grid and Syncfusion.Blazor.Themes packages in your project using the NuGet Package Manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), or the integrated terminal in Visual Studio Code (dotnet add package), or the .NET CLI.

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

Install-Package Syncfusion.Blazor.Grid -Version 33.1.44
Install-Package Syncfusion.Blazor.Themes -Version 33.1.44

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 and import the Syncfusion.Blazor and Syncfusion.Blazor.Grids namespaces.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Grids

Register Syncfusion® Blazor service

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

....
using Syncfusion.Blazor;
....
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 and script references in the ~wwwroot/index.html 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 a Blazor application. Also, see Adding Script Reference to learn different approaches for adding script references in a Blazor application.

Add Syncfusion® Blazor component

Add the Syncfusion® Blazor DataGrid component in the ~/Pages/Index.razor file.

@using Syncfusion.Blazor.Grids

<SfGrid DataSource="@Orders" />

@code{
    public List<Order> Orders { get; set; }

    protected override void OnInitialized()
    {
        Orders = Enumerable.Range(1, 10).Select(x => new Order()
        {
            OrderID = 1000 + x,
            CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
            Freight = 2 * x,
            OrderDate = DateTime.Now.AddDays(-x),
        }).ToList();
    }

    public class Order {
        public int? OrderID { get; set; }
        public string CustomerID { get; set; }
        public DateTime? OrderDate { get; set; }
        public double? Freight { get; set; }
    }
}
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This renders the Syncfusion® Blazor DataGrid component in the default web browser.
