The Text field is a simple text box control. Max length (characters) option defines the maximum amount of characters that can be typed into the field.
For more information about validation, see Validation types.
Masked input is a template that applies a specific format of input. It helps users enter the data (phone numbers, dates, IP addresses, etc.) into the field in a predefined way.
An example of a phone number masked input:
You can use one of the predefined mask formats or create your own custom expression. The following mask definitions are predefined:
•S - Represents an alpha character (A-Z,a-z)
•0 - Represents a numeric character (0-9)
•9 - Represents a numeric character (0-9), optional
•A - Represents an alphanumeric character (A-Z,a-z,0-9)
A few examples of custom expressions:
•US social security number: 000-00-0000
•Date (mm/dd/yyyy): 00/00/0000
•Time (hh:mm:ss): 00:00:00
•Phone number: (000) 000-0000
