Overview
The Telerik UI for ASP.NET Core MaskedTextBox component allows the input of controlled text or numbers based on a specific format. You can easily set its value and mask value, add custom mask rules, prompt characters and culture names. This comes in handy when you require the input of telephone numbers, credit cards, postal codes etc. The component comes with out-of-the-box support for globalization, RTL and validation.
-
Labels
The label enables you to associate the label HTML element with the MaskedTextBox and also makes it easier for users to understand what is asked from them. The component also supports floating labels, meaning that even when the person has started to type in their input, they would be able to see the label above the MaskedTextBox.
-
Validation
The component comes with a set of predefined mask rules, which you can modify to meet your project’s requirements. You can check out the list of predefined rules here or see how to create custom ones in our documentation.
-
Events
You can subscribe to all MaskedTextBox events, such as Change, presented in the demo’s console log after interaction with the component. To explore the available events, refer to the following demo:
-
Declarative Initialization
Declarative initialization—a feature that serializes the component declaration as an MVVM declarative configuration instead of an inline initialization script—is supported in Telerik UI for ASP.NET Core MaskedTextBox. It is beneficial in cases when the Content Security Policy (CSP) is enabled as it eliminates the requirement to call the methods that defer the initialization script generated after the component's HTML markup.

-
Globalization
The Core MaskedTextBox component facilitates quick set up for various culture settings. Take advantage of the globalization functionality to easily translate component messages and adapt to different cultures.
-
HTML and Tag Helpers
The Telerik UI for ASP.NET Core suite offers two approaches to declare the MaskedTextBox or any other component – choose HTML or Tag helpers based on your preference, practice, and technology background, and add this advanced input element to any new or existing form.
-
RTL Support
The MaskedTextBox right-to-left support is available for languages like Arabic and Hebrew, in which users read from right to left. You can satisfy any script preference and facilitate user interaction by toggling between left-to-right and right-to-left alignment with only a few settings.
-
Accessibility
The MaskedTextBox component is Section 508 and WCAG 2.1 guidelines compliant, thus you can rest assured that your application will meet the needs of all users.
