Setting the Mask in .NET MAUI MaskedEntry

The Telerik MaskedEntry for .NET MAUI exposes a Mask(string) property, which represents a string of characters restricting user input. The Mask property can contain literals and special mask characters depending on the used mask type (numeric, text, or regex).

Mask for the TextMaskedEntry

To allow users to enter only numbers inside the RadTextMaskedEntry, apply the Mask for numeric restriction:

<telerik:RadTextMaskedEntry Mask="[phone]" PromptChar=" " AutomationId="textMaskNumbersOnly"/>

To allow users to enter only literals inside the RadTextMaskedEntry, apply the Mask for letter characters restriction:

<telerik:RadTextMaskedEntry Mask="LLLLL" AutomationId="textMaskTextOnly"/>

Mask for RegexMaskedEntry

You can define an input pattern of your choice and set it to the Mask property of the RadRegexMaskedEntry:

<telerik:RadRegexMaskedEntry Mask="^(\+0?1\s)?\(?\d{3}\)?[\s.-]\d{3}[\s.-]\d{4}$" Placeholder="[phone]" AutomationId="regexMaskPhoneNumber"/>
