30 Jun 20266 minutes to read

This guide explains how to include the Blazor TextBox component in a Blazor WebAssembly App using Visual Studio, Visual Studio Code, and the .NET CLI.

Create a new Blazor WASM App

Create a Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Blazor Extension. For detailed instructions, refer to the Blazor WebAssembly App Getting Started documentation.

Run the following command to create a new Blazor WebAssembly App.

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

Alternatively, create a Blazor WebAssembly App using Visual Studio Code via Microsoft Templates, the Blazor Extension, or the C# Dev Kit extension.

Run the following command to create a new Blazor WebAssembly App.

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

Install the required Blazor packages

Install Syncfusion.Blazor.Inputs and Syncfusion.Blazor.Themes NuGet packages. All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details.

  1. Go to Tools → NuGet Package Manager → Manage NuGet Packages for Solution.
  2. Search the required NuGet packages (Syncfusion.Blazor.Inputs and Syncfusion.Blazor.Themes) and install them.

Alternatively, you can install the same packages using the Package Manager Console with the following commands.

Install-Package Syncfusion.Blazor.Inputs -Version 33.2.3
Install-Package Syncfusion.Blazor.Themes -Version 33.2.3

Open the terminal and run the following commands.

dotnet add package Syncfusion.Blazor.Inputs -v 33.2.3
dotnet add package Syncfusion.Blazor.Themes -v 33.2.3

Open the command prompt and run the following commands.

dotnet add package Syncfusion.Blazor.Inputs -v 33.2.3
dotnet add package Syncfusion.Blazor.Themes -v 33.2.3

Add import namespaces

After the packages are installed, open the ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Inputs namespaces.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Inputs

Register the Blazor service

Open the Program.cs file in Blazor WebAssembly App and register the Blazor service.

....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet and script references in the ~wwwroot/index.html file.

...
<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
...
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

Add Blazor TextBox component

Open a Razor file located in the ~/Pages/*.razor (for example, Home.razor) and add the Blazor TextBox component inside the razor file.

@using Syncfusion.Blazor.Inputs

<SfTextBox Placeholder='First Name'></SfTextBox>

Run the application

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. The Blazor TextBox component will render in your default web browser.

Open the terminal and run the following command.

dotnet run

Open the command prompt and run the following command.

dotnet run

Adding icons to the Blazor TextBox

Add an icon to the TextBox component using the AddIconAsync method. The following example shows how to implement this in a Blazor WebAssembly app.

@using Syncfusion.Blazor.Inputs

<div id="sample" style="margin:130px auto;width:300px">
    <SfTextBox @ref=@TextBoxDropDownObj
               Created="@AddDateIcon"
               Placeholder="Enter Date"
               FloatLabelType="@FloatLabelType.Auto">
    </SfTextBox>
</div>


@code {
    SfTextBox TextBoxDropDownObj { get; set; }

    private async void AddDateIcon()
    {
        if (TextBoxDropDownObj != null)
        {
            //Add icon to the TextBox
            await TextBoxDropDownObj.AddIconAsync("append", "e-icons e-date-icon");
}
    }
}

Floating label

The floating label lifts above the input when the TextBox is focused or contains a value. Configure it by setting the FloatLabelType API.

@using Syncfusion.Blazor.Inputs

<SfTextBox Placeholder='First Name' FloatLabelType='@FloatLabelType.Auto'></SfTextBox>
