Need custom control created that supports Phone Number entry. Basically, it will have one public property "PhoneNumber" that binds two ways and 3 text boxes that take input.
What important is that this control should work with validation, i.e. have validation tooltip and border, skinnable just like in regular textbox. So, if I have my VM support INotifyDataErrorInfo this control should support that.
I'm developer myself, ideally want to find Silverlight Guru to provide clean solutions to various UI challenges. I like clean code with no exatra dependencies, etc.
