Description

TMaskEdit implements a generic masked edit control.

Use a TMaskEdit object to put a masked edit control on your form. Masked edit controls validate the text the user enters against a mask that encodes the valid forms the text can take. The mask can also format text that is displayed to the user.

Mask characters

#, 0, 9 Digit. If the mask is '9', the digit is not required. The ANSI range is ['0'; '9'].
A, a Alphanumeric character. If the mask is 'a', the alphanumeric character is not required. The following ANSI ranges are permitted: ['A'; 'Z'], ['a', 'z'], and ['0'; '9'].
C, c Printable character. If the mask is 'c', the character is not required. The permitted ANSI range is [32; 126].

Formatting characters

TMaskEdit implements the generic behavior introduced in TCustomMaskEdit. TMaskEdit publishes many of the properties and methods inherited from TCustomMaskEdit, but does not introduce any new behavior.
