Getting Started with Blazor WebAssembly Standalone App

25 Jun 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 Blazor Templates

You can create a Blazor WebAssembly Standalone App using 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.

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 33.2.3
Install-Package Syncfusion.Blazor.Themes -Version 33.2.3

Open the terminal and run the following commands.

dotnet add package Syncfusion.Blazor.Grid -v 33.2.3
dotnet add package Syncfusion.Blazor.Themes -v 33.2.3

Open the command prompt and run the following commands.

dotnet add package Syncfusion.Blazor.Grid -v 33.2.3
dotnet add package Syncfusion.Blazor.Themes -v 33.2.3

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
