Property Value

Type Description

A mask expression string.


A mask defines a pattern used for entered values. For example, when a text editor should accept a fixed-length string in a pre-defined format (for example, a phone number, zip code, etc).

DevExpress MAUI DataForm - MaskedEditor

Use the Mask property to specify the mask expression. It can include meta and literal characters.

  • A metacharacter is a user input placeholder (identified by the underscore character - _).
    The following table lists the available metacharacters:




    An alphabetic character. For example, A-Z, a-z for the USA.


    A numeric character.


    Any character.

  • A literal character is a fixed part of the mask that cannot be edited. To display a metacharacter as a literal, precede it with a backslash (\).

The following example shows how to specify a mask and apply it to a value of the PersonalInfo object’s Phone property:

using DevExpress.Maui.DataForm;
// ... 

namespace DataFormExample {
    public class PersonalInfo {
        // ...

        [DataFormMaskedEditor(Mask = "(000) 000-0000")]
        public string Phone { get; set; }
