.NET MAUI Text Mask

To validate the user input as text symbols, use the TextMaskedEntry. The resulting value is a string object.

The table below lists the mask characters that can be used with TextMaskedEntry. The characters can be set to the Mask property.

Mask Character	Description
0	(Required) Digit. This element will accept any single digit between 0 and 9.
9	(Optional) Digit or space.
#	(Optional) Digit or space. If this position is blank in the mask, it will be rendered as the character in the PromptChar property. For example, "$######.##" displays as a literal "$", accepts a numeric amount with six places and two places to the right of the decimal, that is, $123456.56.
L	(Required) Accepts letters only.
?	(Optional) Letter.
&	(Required) Character.
C	(Optional) Character.
A	(Required) Alphanumeric. Accepts any symbol.
a	(Optional) Alphanumeric.
.	Decimal placeholder.
,	Thousands placeholder.
:	Time separator.
/	Date separator.
$	Currency symbol.
<	Shifts down. Converts all characters that follow to lowercase.
>	Shifts up. Converts all characters that follow to uppercase.
\	Disables a previous shift up or shift down.
\\	Escape. Escapes a mask character, turning it into a literal. "\\" is the escape sequence for a backslash.
All other characters	All non-mask elements will appear as themselves within RadTextMaskedEntry. Literals always occupy a static position in the mask at run time, and cannot be moved or deleted by the user.

The following example demonstrates how to create a RadTextMaskedEntry:

xaml

<telerik:RadTextMaskedEntry x:Name="textMaskedEntry" Mask="aaaaaaaaaaaaaaaaaaaa" AutomationId="textMask" />

The image below shows the end result.

For the MaskedEntry Text Mask examples, go to the SDKBrowser Demo Application and navigate to MaskedEntry -> Mask Types category.
