You can restrict the type and format of data that users enter into fields and other controls. For example, you can make sure that only valid telephone numbers are entered.
You can set the type of data such as string, integer, or date, and you can specify constraints such as an allowed range of numbers, or specify a template that the input must match. You can also set up a field to automatically show data in a format such as a date, a currency, or to match a custom pattern.
