Property Value

Type	Description
String	A mask expression string.

Remarks

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).

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:

  Character	Description
  L	An alphabetic character. For example, A-Z, a-z for the USA.
  0	A numeric character.
  C	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 data object’s Phone property:

XAML

<dxdf:DataFormView x:Name="dataForm">
    <!--...-->
    <dxdf:DataFormMaskedItem FieldName="Phone" Mask="[phone]"/>
</dxdf:DataFormView>
