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

To get started quickly with the Blazor Media Query component, you can check out this video.

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 Core and Themes NuGet in the App

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

Install-Package Syncfusion.Blazor.Core  -Version 25.2.3
Install-Package Syncfusion.Blazor.Themes -Version 25.2.3

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 namespace.

@using Syncfusion.Blazor

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

The theme stylesheet can be accessed from NuGet through Static Web Assets. Reference the stylesheet 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" />
</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.

Add Syncfusion Blazor Media Query component

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

<SfMediaQuery @bind-ActiveBreakPoint="activeBreakpoint"></SfMediaQuery>
<br />
@if (activeBreakpoint == "Small")
{
    deviceSize = "small-device";
}
else if (activeBreakpoint == "Medium")
{
    deviceSize = "medium-device";
}
else
{
    deviceSize = "";
}

<div class="mediaquery-demo @deviceSize">
    <div class="header e-skeleton e-skeleton-text">
        <div class="search-box e-skeleton e-skeleton-text"></div>
    </div>
    <div class="banner e-skeleton e-skeleton-text e-shimmer-pulse"></div>
    <div class="main-container">
        <ul>
            <li>
                <div class="content e-skeleton e-skeleton-text e-shimmer-pulse"></div>
                <div class="title e-skeleton e-skeleton-text e-shimmer-pulse"></div>
                <p class="e-skeleton e-skeleton-text e-shimmer-pulse"></p>
            </li>
            <li>
                <div class="content e-skeleton e-skeleton-text e-shimmer-pulse"></div>
                <div class="title e-skeleton e-skeleton-text e-shimmer-pulse"></div>
                <p class="e-skeleton e-skeleton-text e-shimmer-pulse"></p>
            </li>
        </ul>
    </div>
    <div class="footer e-skeleton e-skeleton-text"></div>
