Masked text box

The masked text box control lets you restrict input to certain types of characters, text, and numbers using mask characters or regex. This control is used to create a template for providing information such as telephone numbers, IP addresses, product IDs, and so on.


Special symbols like currency symbols, date separators, decimal separators, and more are applied based on the provided culture.

Custom prompt character

The masked text box control provides the flexibility to customize the prompt character.

Validation mode

The input validation can be done either during each key press or when the control loses its focus.


The watermark will prompt users with instructions or important information when it is not in focus and any valid characters are not entered.
