The Wisej.NET MaskedTextBox enhances the TextBox control with declarative input validation. The Mask property enables specifying:
Required input characters
Optional input characters
Input type expected at each mask position (digit, alphabetic, alphanumeric)
Mask literals (characters appearing directly in the MaskedTextBox, like hyphens in phone numbers or currency symbols)
Special character processing (e.g., converting to uppercase)
The custom mask property editor provides selection from predefined, commonly used masks.
The InvalidMessage property sets a tooltip message for invalid entries.
The TypeValidationCompleted event handler enables custom validation behavior.
The TextMaskFormat property determines literal and prompt character processing in the formatted string, controlling their inclusion in the Text property. Excluded prompt characters convert to spaces.
ExcludePromptAndLiterals: Shows only user input text
IncludeLiterals: Shows user input and mask literal characters
IncludePrompt: Shows user input and prompt characters
IncludePromptAndLiterals: Shows user input, literal characters, and prompt characters
Customize text color using the ForeColor property.
