23 Jul 20263 minutes to read

This section briefly explains how to include the ASP.NET Core Masked Textbox control in your ASP.NET Core application using Visual Studio.

Create an ASP.NET Core Web App with Razor pages

Create an ASP.NET Core Web App using Visual Studio via Microsoft Templates or the Syncfusion® ASP.NET Core Extension. For detailed instructions, refer to the ASP.NET Core Web App Getting Started documentation.

Install the required ASP.NET Core packages

To add ASP.NET Core Masked Textbox control in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for and install the Syncfusion.AspNetCore.Inputs and Syncfusion.AspNetCore.Themes packages. All Syncfusion ASP.NET Core packages are available on nuget.org. See the NuGet packages topic for details.

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

Install-Package Syncfusion.AspNetCore.Inputs -Version 34.1.29
Install-Package Syncfusion.AspNetCore.Themes -Version 34.1.29

Add ASP.NET Core Tag Helpers

After the packages are installed, open the ~/Pages/_ViewImports.cshtml file and import the Syncfusion.AspNetCore.Base and Syncfusion.AspNetCore.Inputs Tag Helpers.

@addTagHelper *, Syncfusion.AspNetCore.Base
@addTagHelper *, Syncfusion.AspNetCore.Inputs

Add stylesheet and script resources

The theme stylesheet and script can be referenced from CDN. Include the stylesheet and script references inside the <head> of ~/Pages/Shared/_Layout.cshtml file.

<head>
    ...
    @* ASP.NET Core controls styles *@
    <link rel="stylesheet" href="_content/Syncfusion.AspNetCore.Themes/styles/fluent2.css" />
    @* ASP.NET Core controls scripts *@
    <script src="_content/Syncfusion.AspNetCore.Inputs/scripts/sf-maskedtextbox.min.js"></script>
</head>

Register the Script Manager

Open the ~/Pages/Shared/_Layout.cshtml file and register the script manager <ejs-scripts> at the end of the <body> element as follows.

<body>
    ...
    @* ASP.NET Core Script Manager *@
    <ejs-scripts></ejs-scripts>
</body>

Add ASP.NET Core Masked Textbox control

Add the ASP.NET Core Masked Textbox control in the ~/Pages/Index.cshtml file.

<ejs-maskedtextbox id="mask1"></ejs-maskedtextbox>

Run the application

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. The ASP.NET Core Masked Textbox control will render in your default web browser.

Set the mask

You can set the mask to the Masked Textbox to validate the user input by using the mask property. To know more about the usage of mask and configuration, refer to this link.

The following example demonstrates the usage of mask element 0 that allows any single digit from 0 to 9.

<ejs-maskedtextbox id="mask1" mask="000-000-0000" placeholder="MaskedTextBox" floatLabelType="Always"></ejs-maskedtextbox>
