# Valid MaskedTextBox

The MaskedTextBox provides options for indicating that the submitted input is not valid.

To indicate to the user that the typed character is not allowed, use the [`valid`](https://www.telerik.com/kendo-vue-ui-develop/components/inputs/api/maskedtextboxprops#valid) property of the MaskedTextBox.
