Importing Syncfusion Blazor component in the application

  • Install Syncfusion.Blazor.Inputs NuGet package to the application by using the NuGet Package Manager.

    Please ensure to check the Include prerelease option for the Beta release.

  • The client-side resources can be added 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 packages.

@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>

Adding icons to the TextBox

A TextBox can be created with icon as a group by creating the parent div element with the class e-input-group and add the icon element as span with the class e-input-group-icon.

<div class='e-input-group'>
    <input class='e-input' Placeholder='Date of Birth' type='text'>
    <span class='e-input-group-icon e-input-calendar'></span>
</div>

<style>
.e-input-group-icon:before {
  font-family: e-icons;
}

.e-input-group .e-input-group-icon.e-input-calendar {
  font-size: 16px;
}

.e-input-group-icon.e-input-calendar:before {
  content: "";
}
</style>
