us phone number format in blackberry [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and开发者_运维百科 cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 10 years ago.

I am using a BasicEditfield.Filter_phone field...in my app. and taking maximum 10 char in it ....but i want to enter the numbers in this field...in (###-###-####) format...

How can I achieve this ?

I'm not aware of any US format only phone number fields. Why not create your own component to store the data?

This could be made up of three text fields with label fields in between them to represent the dashes.
