30 Jan 20246 minutes to read

This section briefly explains about how to include Blazor SpeedDial component in your Blazor Server App and Blazor WebAssembly App using Visual Studio.

To get start quickly with SpeedDial Component using Blazor, you can check on this video or GitHub sample.

Prerequisites

Create a new Blazor App in Visual Studio

You can create a Blazor Server App or Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Syncfusion Blazor Extension.

Install Syncfusion Blazor Buttons and Themes NuGet in the App

To add Blazor SpeedDial 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.Buttons and Syncfusion.Blazor.Themes. Alternatively, you can utilize the following package manager command to achieve the same.

Install-Package Syncfusion.Blazor.Buttons -Version 27.2.2
Install-Package Syncfusion.Blazor.Themes -Version 27.2.2

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.Buttons namespace.

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

Now, register the Syncfusion Blazor Service in the ~/Program.cs file of your Blazor Server App or Blazor WebAssembly App.

using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....
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 can be accessed from NuGet through Static Web Assets. Reference the stylesheet and script in the <head> of the main page as follows:

  • For .NET 6 Blazor Server app, include it in ~/Pages/_Layout.cshtml file.

  • For .NET 7 Blazor Server app, include it in the ~/Pages/_Host.cshtml file.

  • For Blazor WebAssembly app, include it in the ~/index.html file.

<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

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 Blazor SpeedDial component

Add the Syncfusion Blazor SpeedDial component in the ~/Pages/Index.razor file.

@using Syncfusion.Blazor.Buttons

<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 your 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.
    }
}
