Flex Examples
In a previous example, “Wrapping values on a Spark Spinner control in Flex 4″, we saw how you could wrap values in a Spark Spinner control in Flex 4 by setting the Boolean allowValueWrap property.
The following example shows how you can wrap values in a Spark NUmericStepper control in Flex 4 by setting the Boolean allowValueWrap property.
The following example(s) require Flash Player 10 and the Adobe Flex 4 SDK. To download the Adobe Flash Builder 4 trial, see http://www.adobe.com/products/flex/. To download the latest nightly build of the Flex 4 SDK, see http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.
For more information on getting started with Flex 4 and Flash Builder 4, see the official Adobe Flex Team blog.

Or you can set the allowValueWrap property using ActionScript, as seen in the following example:

This entry is based on a beta version of the Flex 4 SDK and therefore is very likely to change as development of the Flex SDK continues. The API can (and will) change causing examples to possibly not compile in newer versions of the Flex 4 SDK.
