25 Jul 20244 minutes to read
This section briefly explains about how to include Blazor TextBox component in your Blazor Web App using Visual Studio.
Prerequisites
Create a new Blazor Web App
You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion Blazor Extension.
You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.
Install Syncfusion Blazor Inputs and Themes NuGet in the App
To add Blazor TextBox 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.Inputs and Syncfusion.Blazor.Themes.
If you utilize WebAssembly or Auto
render modes in the Blazor Web App need to be install Syncfusion Blazor components NuGet packages within the client project.
Alternatively, you can utilize the following package manager command to achieve the same.
Install-Package Syncfusion.Blazor.Inputs -Version 27.1.48
Install-Package Syncfusion.Blazor.Themes -Version 27.1.48
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
and Syncfusion.Blazor.Inputs
namespace .
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Inputs
Now, register the Syncfusion Blazor Service in the ~/Program.cs file of your Blazor Web App.
If you select an Interactive render mode as WebAssembly
or Auto
, you need to register the Syncfusion Blazor service in both ~/Program.cs files of your Blazor Web App.
....
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 reference in the <head>
section and the script reference at the end of the <body>
in the ~/Components/App.razor file as shown below:
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>
<body>
....
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>
NOTE
Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.
Add Syncfusion Blazor TextBox component
Add the Syncfusion Blazor TextBox component in the ~Pages/.razor file. If an interactivity location as Per page/component
in the web app, define a render mode at the top of the ~Pages/.razor
component, as follows:
@* desired render mode define here *@
@rendermode InteractiveAuto
<SfTextBox Placeholder='First Name'></SfTextBox>
- Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion Blazor TextBox component in your default web browser.
NOTE
Adding icons to the Blazor TextBox
You can add an icon to the TextBox component using the AddIconAsync method. Below is an example of how to implement this in your Blazor application:
@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 TextBox floats the label above the TextBox after focusing, or filled with value in the TextBox. The floating label TextBox can be created by using the FloatLabelType API.
<SfTextBox Placeholder='First Name' FloatLabelType='@FloatLabelType.Auto'></SfTextBox>
