Questions tagged [maskedtextbox]

A useful .NET control that allows a user to display and edit values based on the mask defined.

The MaskedTextBox class is a .NET/Windows Forms enhanced TextBox control that supports a declarative syntax for accepting or rejecting user input.

For example, in order to get a phone number in the format (505) 55 555 555, MaskedTextBox is preferred.

Using the Mask property, you can specify the following input without writing any custom validation logic in your application:

  • Required input characters.

  • Optional input characters.

  • The type of input expected at a given position in the mask; for example, a digit, or an alphabetic or alphanumeric character.

  • Mask literals, or characters that should appear directly in the MaskedTextBox; for example, the hyphens (-) in a phone number, or the currency symbol in a price.

  • Special processing for input characters; for example, to convert alphabetic characters to uppercase.

For more information, see MaskedTextBox Class (MSDN).
