Prerequisites

Install the latest version of .NET SDK. If you previously installed the SDK, you can determine the installed version by executing the following command in a command prompt (Windows) or terminal (macOS) or command shell (Linux).

dotnet --version

Create a Blazor Web App using .NET CLI

Run the following command to create a new Blazor Web App in a command prompt (Windows) or terminal (macOS) or command shell (Linux). For detailed instructions, refer to this Blazor Web App Getting Started documentation.

Configure the appropriate interactive render mode and interactivity location when setting up a Blazor Web Application. For detailed information, refer to the interactive render mode documentation.

For example, to create a Blazor Web App with the Auto interactive render mode, use the following commands:

dotnet new blazor -o BlazorApp -int Auto
cd BlazorApp
cd BlazorApp.Client

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

Install Syncfusion® Blazor Buttons and Themes NuGet in the App

Here’s an example of how to add Blazor Speed Dial component in the application using the following command in the command prompt (Windows) or terminal (Linux and macOS) to install a Syncfusion.Blazor.Buttons and Syncfusion.Blazor.Themes NuGet package. See Install and manage packages using the dotnet CLI topics for more details.

If using the WebAssembly or Auto render modes in the Blazor Web App, install Syncfusion® Blazor component NuGet packages in the client project.

dotnet add package Syncfusion.Blazor.Buttons --version 32.1.19
dotnet add package Syncfusion.Blazor.Themes --version 32.1.19
dotnet restore

NOTE

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

Add Import Namespaces

Open the ~/_Imports.razor file from the client project and import the Syncfusion.Blazor and Syncfusion.Blazor.Buttons namespaces.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Buttons

Register Syncfusion® Blazor Service

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

If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion® Blazor service in the ~/Program.cs files of the main server project and associated .Client project.

...
...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents()
    .AddInteractiveWebAssemblyComponents();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....
...
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
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. Add the stylesheet reference in the head and the script reference at the end of the body in ~/Components/App.razor as shown below. The script enables client-side interactivity for Syncfusion components.

<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 SpeedDial component

Add the Syncfusion® Blazor SpeedDial component to a Razor page located under the Pages folder (e.g., Pages/Home.razor) in either the Server or Client project. If an interactivity location as Per page/component in the web app, define a render mode at top of the component, as follows:

Interactivity location RenderMode Code
Per page/component Auto @rendermode InteractiveAuto
  WebAssembly @rendermode InteractiveWebAssembly
  None —

NOTE

If an Interactivity Location is set to Global and the Render Mode is set to Auto or WebAssembly, the render mode is configured in the App.razor file by default.

@* desired render mode define here *@
@rendermode InteractiveAuto
<div id="target" style="min-height:200px; position:relative; width:300px; border:1px solid;">
    <SfSpeedDial Target="#target" Content="Edit">
        <SpeedDialItems>
            <SpeedDialItem Text="Cut"/>
            <SpeedDialItem Text="Copy"/>
            <SpeedDialItem Text="Paste"/>
        </SpeedDialItems>
    </SfSpeedDial>
</div>
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion® Blazor SpeedDial component in the default web browser.

Linear and radial display modes

You can use the Mode property to either display the menu in linear order like a list or like a radial menu in radial (circular) direction.

<div id="target" style="min-height:200px; position:relative; width:300px; border:1px solid;">
    <SfSpeedDial Target="#target" Position="FabPosition.BottomLeft" Mode="SpeedDialMode.Radial" OpenIconCss="e-icons e-edit">
        <SpeedDialRadialSettings OffSet="80px"/>
        <SpeedDialItems>
            <SpeedDialItem IconCss="e-icons e-cut"/>
            <SpeedDialItem IconCss="e-icons e-copy"/>
            <SpeedDialItem IconCss="e-icons e-paste"/>
        </SpeedDialItems>
    </SfSpeedDial>
    <SfSpeedDial Target="#target" Position="FabPosition.BottomRight" Mode="SpeedDialMode.Linear" OpenIconCss="e-icons e-edit">
        <SpeedDialItems>
            <SpeedDialItem IconCss="e-icons e-cut" Text="Cut"/>
            <SpeedDialItem IconCss="e-icons e-copy" Text="Copy"/>
            <SpeedDialItem IconCss="e-icons e-paste" Text="Paste"/>
        </SpeedDialItems>
    </SfSpeedDial>
</div>

Item clicked event

The speed dial control triggers the ItemClicked event with SpeedDialItemEventArgs argument when an action item is clicked. You can use this event to perform the required action.

<div id="target" style="min-height:200px; position:relative; width:300px; border:1px solid;">
    <SfSpeedDial Target="#target" OpenIconCss="e-icons e-edit" ItemClicked="ItemEventClick">
        <SpeedDialItems>
            <SpeedDialItem IconCss="e-icons e-cut" Text="Cut"/>
            <SpeedDialItem IconCss="e-icons e-copy" Text="Copy"/>
            <SpeedDialItem IconCss="e-icons e-paste" Text="Paste"/>
        </SpeedDialItems>
    </SfSpeedDial>
</div>

@code{
    public void ItemEventClick(SpeedDialItemEventArgs args)
    {
        // Here, you can call your desired action.
    }
}
