问题
I need a WPF Textbox that displays a phone number as "(555) 555-5555" but has a value of "5555555555".
All of the examples I'm seeing have the ability to mask the control on the UI but that affects the bound property of my view model so that the property value has the extraneous ()- characters.
回答1:
How about an IValueConverter?

I am thinking that you will probably have to roll-your-own. It shouldn't be too difficult, subclass and override to obtain the results you are looking for.
