Importing Syncfusion Blazor component in the application

  • You can add the client-side resources through CDN or from NuGet package in the HEAD element of the ~/wwwroot/index.html page.

      <head>
              <link href="_content/Syncfusion.Blazor.Themes/bootstrap4.css" rel="stylesheet" />
              <!-- <link href="https://cdn.syncfusion.com/blazor//styles/.css" rel="stylesheet" /> -->
      </head>

    For Internet Explorer 11 kindly refer the polyfills. Refer the documentation for more information.

      <head>
          <link href="_content/Syncfusion.Blazor.Themes/bootstrap4.css" rel="stylesheet" />
          <script src="https://github.com/Daddoon/Blazor.Polyfill/releases/download/3.0.1/blazor.polyfill.min.js"></script>
      </head>

Adding component package to the application

Open ~/_Imports.razor file and import the Syncfusion.Blazor.Inputs package.

@using Syncfusion.Blazor.Inputs

Add SyncfusionBlazor service in Program.cs

Open the Program.cs file and add services required by Syncfusion components using builder.Services.AddSyncfusionBlazor() method.

using Syncfusion.Blazor;

namespace BlazorApplication
{
    public class Program
    {
        public static async Task Main(string[] args)
        {
            ....
            ....
            builder.Services.AddSyncfusionBlazor();
            await builder.Build().RunAsync();
        }
    }
}

To enable custom client side resource loading from CRG or CDN. You need to disable resource loading by AddSyncfusionBlazor(true) and load the scripts in the HEAD element of the ~/wwwroot/index.html page.

<head>
    <script src="https://cdn.syncfusion.com/blazor/19.3.43/syncfusion-blazor.min.js"></script>
</head>
