Prerequisites

Create a new Blazor App in Visual Studio

Create a Blazor WebAssembly app using Visual Studio via Microsoft templates or the Syncfusion® Blazor extension.

Install Syncfusion® Blazor Notifications and Themes NuGet in the App

Install Syncfusion.Blazor.Notifications and Syncfusion.Blazor.Themes using the NuGet Package Manager (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), or run the following commands:

Install-Package Syncfusion.Blazor.Notifications -Version 31.2.2
Install-Package Syncfusion.Blazor.Themes -Version 31.2.2

NOTE

Syncfusion® Blazor components are available on nuget.org. Refer to the NuGet packages topic for the list of available packages and component details.

Prerequisites

Create a new Blazor App in Visual Studio Code

Create a Blazor WebAssembly app using Visual Studio Code via Microsoft templates or the Syncfusion® Blazor extension.

Alternatively, create a WebAssembly application using the following commands in the integrated terminal:

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

Install Syncfusion® Blazor Notifications and Themes NuGet in the App

Use the integrated terminal in Visual Studio Code from the project root (where the .csproj file is located), then run:

dotnet add package Syncfusion.Blazor.Notifications -v 31.2.2
dotnet add package Syncfusion.Blazor.Themes -v 31.2.2
dotnet restore

NOTE

Syncfusion® Blazor components are available on nuget.org. Refer to the NuGet packages topic for the list of available packages and component details.

Register Syncfusion® Blazor Service

Open ~/_Imports.razor and import the Syncfusion.Blazor and Syncfusion.Blazor.Notifications namespaces:

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Notifications

Register the Syncfusion® Blazor service in ~/Program.cs of the Blazor WebAssembly app:

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();

Add stylesheet and script resources

The theme stylesheet and script are provided via NuGet as Static Web Assets. Include the stylesheet and script references in the <head> section of ~/wwwroot/index.html:

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

NOTE

See the Blazor Themes topic to discover options for referencing themes (Static Web Assets, CDN, and CRG). Also, see Adding Script Reference for different approaches to add script references in a Blazor application.

Add Blazor Toast component

Add the Syncfusion® Blazor Toast component to ~/Pages/Index.razor:

<div class="col-lg-12 control-section toast-default-section">
    <SfToast ID="toast_default" @ref="ToastObj" Title="Adaptive Tiles Meeting" Content="@ToastContent" Timeout="5000" Icon="e-meeting">
        <ToastPosition X="@ToastPosition"></ToastPosition>
    </SfToast>
    <div class="col-lg-12 col-sm-12 col-md-12 center">
        <div id="toastBtnDefault" style="margin: auto; text-align: center">
            <button class="e-btn" @onclick="@ShowOnClick">Show Toasts</button>
            <button class="e-btn" @onclick="@HideOnClick">Hide All</button>
        </div>
    </div>
</div>

<style>
    #toast_default .e-meeting::before {
        content: "\e705";
        font-size: 17px;
    }

    .bootstrap4 #toast_default .e-meeting::before {
        content: "\e763";
        font-size: 20px;
    }
</style>

@code {
    private SfToast ToastObj;
    private string ToastPosition = "Right";
    private string ToastContent = "Conference Room 01 / Building 135 10:00 AM-10:30 AM";

    private async Task ShowOnClick()
    {
        await ToastObj.ShowAsync();
    }

    private async Task HideOnClick()
    {
        await ToastObj.HideAsync("All");
    }
}

Launch the application with Ctrl+F5 (Windows) or +F5 (macOS). The Syncfusion® Blazor Toast component renders in the default web browser.
