Getting Started with Blazor WebAssembly Standalone App

16 Jul 20266 minutes to read

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

Using Playground

Blazor Playground allows interaction with Blazor components directly in a web browser without needing to install any NuGet packages.

Using Templates

Quickly set up a Blazor application using the preconfigured Syncfusion WebAssembly App Template.

First, install the template using the .NET CLI.

dotnet new install Syncfusion.Blazor.WebAssemblyApp.Templates

Next, create a new project with following command.

dotnet new syncfusionblazorwasmapp --name MyApp --pwa true

After creating the project, navigate to the main project folder (for example, MyApp) and run the following command.

  • .NET CLI
    • cd MyApp
dotnet run

    Manually creating a project

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

    Create a new Blazor WebAssembly (Standalone) App

    Create a Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Blazor Extension.

    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 or the 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.Grid 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.Grid 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.Grid -Version 34.1.29
Install-Package Syncfusion.Blazor.Themes -Version 34.1.29

    Open the terminal and run the following commands.

    dotnet add package Syncfusion.Blazor.Grid -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29

    Open the command prompt and run the following commands.

    dotnet add package Syncfusion.Blazor.Grid -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29

    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 the Blazor service

    Open the Program.cs file in Blazor WebAssembly App and register the Blazor service.

    ....
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>

    Add Blazor DataGrid component

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

    @using Syncfusion.Blazor.Grids

<SfGrid DataSource="@Orders" />

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

    protected override void OnInitialized()
    {
        var customers = new string[] { "James Hopper", "Michael Smith", "Sarah Johnson", "Robert Davis", "Emily Wilson" };
        var cities = new string[] { "New York", "Los Angeles", "Chicago", "Houston", "Phoenix" };
        var rng = new Random();
        Orders = Enumerable.Range(1, 10).Select(x => new Order()
        {
            OrderID = 1000 + x,
            CustomerName = customers[rng.Next(customers.Length)],
            ShipCity = cities[rng.Next(cities.Length)],
            Freight = Math.Round(10.5 + (x * 7.3), 2),
            OrderDate = DateTime.Now.AddDays(-x),
        }).ToList();
    }

    public class Order {
        public int? OrderID { get; set; }
        public string CustomerName { get; set; }
        public string ShipCity { get; set; }
        public DateTime? OrderDate { get; set; }
        public double? Freight { get; set; }
    }
}

    Run the application

    Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. The Blazor DataGrid 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
    Blazor DataGrid Component
