29 Nov 20244 minutes to read

This section briefly explains about how to include Blazor Toast component in your Blazor Web App using Visual Studio.

Prerequisites

Create a new Blazor Web App

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion® Blazor Extension.

You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.

Install Syncfusion® Blazor Notifications and Themes NuGet in the App

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

If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion® Blazor components NuGet packages within the client project.

Alternatively, you can utilize the following package manager command to achieve the same.

Install-Package Syncfusion.Blazor.Notifications -Version 28.1.33
Install-Package Syncfusion.Blazor.Themes -Version 28.1.33

NOTE

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

Register Syncfusion® Blazor Service

Open ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Notifications namespace .

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

Now, register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Web App.

If you select an Interactive render mode as WebAssembly or Auto, you need to register the Syncfusion® Blazor service in both ~/Program.cs files of your Blazor Web 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 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

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

Add Syncfusion® Blazor Toast component

Add the Syncfusion® Blazor Toast component in the ~Pages/.razor file. If an interactivity location as Per page/component in the web app, define a render mode at the top of the ~Pages/.razor component, as follows:

@* desired render mode define here *@
@rendermode InteractiveAuto
<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 {
    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 this.ToastObj.ShowAsync();
    }
    private async Task HideOnClick()
    {
        await this.ToastObj.HideAsync("All");
    }
}
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion® Blazor Toast component in your default web browser.
