InputMask component

The <InputMask> helps the user with the input by ensuring a predefined format. This can be useful for dates, numerics, phone numbers, ...

  • 9: numeric
  • a: alphabetical
  • *: alphanumeric

Basic Example

To start you only need to define the Mask parameter.
<InputMask Mask="99-9999999" />

Default masking definitions

Alias Example

Instead of masking an input element, it is also possible to use the inputmask for formatting given values.
<InputMask Alias="datetime" InputFormat="dd/mm/yyyy" OutputFormat="ddmmyyyy" />
