MaskedTextBox HtmlHelper Overview

The Telerik UI MaskedTextBox HtmlHelper for ASP.NET Core is a server-side wrapper for the Kendo UI MaskedTextBox widget.

The MaskedTextBox enables a controlled text input that is based on a specific format. The helper enables you to define its value and mask value, and set custom mask rules, prompt characters, and culture names. Each mask can contain mask rules and mask literals. The mask literals are automatically entered for the user and cannot be removed. You can also use the MaskedTextBox predefined rules which specify the required or optional digit, letter, or character input.

Basic Configuration

The following example demonstrates the basic configuration for the MaskedTextBox.

    @(Html.Kendo().MaskedTextBox()
        .Name("maskedtextbox") // The name of the MaskedTextBox is mandatory. It specifies the "id" attribute of the MaskedTextBox.
        .Mask("(000) 000-0000") // Set the mask value of the MaskedTextBox.
        .Value("(123) 345-6789") // Set the value of the MaskedTextBox.
    )

Functionality and Features

Events

You can subscribe to all MaskedTextBox events. For a complete example on basic MaskedTextBox events, refer to the demo on using the events of the MaskedTextBox.

The following example demonstrates how to subscribe to events by a handler name.

  @(Html.Kendo().MaskedTextBox()
        .Name("maskedtextbox")
        .Events(e => e
            .Change("maskedtextbox_change")
        )
  )
  <script>
  function maskedtextbox_change() {
      // Handle the change event.
  }
  </script>

Referencing Existing Instances

To reference an existing Telerik UI MaskedTextBox instance, use the jQuery.data() method. Once a reference is established, use the MaskedTextBox client-side API to control its behavior.

The following example demonstrates how to access an existing MaskedTextBox instance.

  // Place the following after your Telerik UI MaskedTextBox for ASP.NET Core declaration.
  <script>
  $(function() {
      // The Name() of the MaskedTextBox is used to get its client-side instance.
      var maskedtextbox = $("#maskedtextbox").data("kendoMaskedTextBox");
  });
  </script>
