You can use the NumericStepper component anywhere you want a user to select a numeric value. For example, you could use a NumericStepper component in a form to set the month, day, and year of a credit card expiration date. You could also use a NumericStepper component to allow a user to increase or decrease a font size.
The NumericStepper component handles only numeric data. Also, you must resize the stepper while authoring to display more than two numeric places (for example, the numbers 5246 or 1.34).
You can enable or disable a NumericStepper in an application. In the disabled state, a NumericStepper doesn't receive mouse or keyboard input. When it's enabled, the NumericStepper receives focus if you click it or tab to it, and its internal focus is set to the text box. When a NumericStepper instance has focus, you can use the following keys to control it:
|
