Register Syncfusion® Blazor Service
Open ~/_Imports.razor file and import the Syncfusion.Blazor namespace.
@using Syncfusion.BlazorNow, register the Syncfusion® Blazor Service in the ~/Program.cs file of your 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
The theme stylesheet can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section of 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 = "";
